+
+1. Easy Build Instructions
+
+This quick summary is no substitute for reading the full build instruc-
+tions later in this document.
+
+Edit xc/config/cf/site.def for local preferences. If you want to build
+with gcc uncomment the HasGcc2 line. If you want to install somewhere
+other than /usr/X11R6.3, change ProjectRoot. (Do not use DESTDIR.)
+
+If any fixes have been released by the X Consortium, stop here and fol-
+low the instructions at the top of each patch, but don't do any of the
+make commands suggested in the patches. Then continue here.
+
+Check the appropriate vendor-specific .cf file in xc/config/cf/ to make
+sure that OSMajorVersion and OSMinorVersion are set correctly for your
+system. Override them in site.def if necessary.
+
+See if there is a BootstrapCFlags mentioned in the comments in the
+vendor-specific .cf file. If there isn't one, cd to the xc directory
+and type:
+
+ % make World >& world.log
+
+
+If there is a BootstrapCFlags, take its value and type:
+
+ % make World BOOTSTRAPCFLAGS="value" >& world.log
+
+
+Do not call the output file "make.log" when doing "make World". After a
+successful build, you can install with:
+
+ % make install >& install.log
+
+
+You can install manual pages with:
+
+ % make install.man >& man.log
+
+
+While the system is building (or if things fail), read the rest of these
+installation instructions.
+
+
+
+2. Building X
+
+
+This document gives detailed instructions for building Release 6: get-
+ting it off the distribution medium, configuring, compiling, installing,
+running, and updating.
+
+Release Notes are in xc/RELNOTES.* (various formats) in the distribu-
+tion.
+
+More recent information about newly-discovered problems may be found in
+the Frequently Asked Questions posting appearing monthly on the
+comp.windows.x newsgroup and xpert mailing list. It is also available
+via anonymous FTP on ftp.x.org in the file contrib/faqs/FAQ.Z, or on
+your local X mirror site.
+
+
+2.1. Preparing the Site
+
+
+If you are unpacking tar files, you will need about 130 Mb to hold the
+xc/ part. To install requires 30-50 Mb assuming you have shared
+libraries (80-100 Mb without). You will need an equivalent amount of
+extra space to build, since you also need room for all the object files.
+
+Distributed as tar files, Release 6.3 core is divided into parts as fol-
+lows:
+
+
+ xc-1.tar contains everything in xc/ that isn't in the other tar files
+ xc-2.tar contains xc/fonts, xc/doc/specs, xc/util
+ xc-3.tar contains xc/doc/hardcopy
+
+
+If you define BuildFonts to NO, you only need to unpack xc-1.tar to
+build. If you build fonts, then you will also need xc-2.tar to build.
+
+
+2.2. Unpacking the Distribution
+
+
+The distribution normally comes as multiple tar files, either on tape or
+across a network, or as a CD-ROM.
+
+
+2.2.1. Unpacking a Compressed FTP Distribution
+
+
+If you have obtained compressed tar files over the network, create a
+directory to hold the sources and cd into it:
+
+ mkdir sourcedir
+ cd sourcedir
+
+Then for each tar file xc-*.tar.Z, execute this:
+
+ zcat ftp-dir/xc-N.tar.Z | tar xf -
+
+
+
+2.2.2. Unpacking a gzipped FTP Distribution
+
+
+If you have obtained gzipped tar files over the network, create a direc-
+tory to hold the sources and cd into it:
+
+ mkdir sourcedir
+ cd sourcedir
+
+Then for each tar file xc-*.tar.gz, execute this:
+
+ gunzip -c ftp-dir/xc-N.tar.gz | tar xf -
+
+
+
+2.2.3. Unpacking a Split Compressed FTP Distribution
+
+
+If you have obtained compressed and split tar files over the network,
+create a directory to hold the sources:
+
+ mkdir sourcedir
+
+Then for each directory xc-*:
+
+ cd ftp-dir/xc-N
+ cat xc-N.?? | uncompress | (cd sourcedir; tar xf -)
+
+
+
+2.2.4. Unpacking the Tape Distribution
+
+
+If you have obtained a tape, create a directory to hold the sources and
+untar everything into that directory:
+
+ mkdir sourcedir
+ cd sourcedir
+ tar xf tape-device
+
+
+
+2.2.5. Using the CD-ROM
+
+
+If you have obtained a CD-ROM, you don't have to do anything to unpack
+it. However, you will have to create a symbolic link tree to build X.
+See the next section.
+
+To mount the CD-ROM, see the mount(8) manual page on your system or the
+liner notes that came with the CD-ROM. Some systems, e.g., Solaris 2,
+can automatically mount the CD-ROM for you.
+
+
+2.3. Apply Patches
+
+
+If there are fixes released that are more recent than your distribution,
+apply them now. Follow the instructions at the top of each patch, but
+don't do any make commands. See the section "Public Patches" later in
+this document. Then continue here.
+
+
+2.4. Symbolic Link Trees
+
+
+If you expect to build the distribution on more than one machine using a
+shared source tree, or you are building from CD-ROM, or you just want to
+keep the source tree pure, you may want to use the program
+xc/config/util/lndir.c to create a symbolic link tree on each build
+machine. The links may use an additional 10 megabytes, but it is
+cheaper than having multiple copies of the source tree.
+
+It may be tricky to compile lndir before the distribution is built. If
+you have a copy from a previous release, use that. Makefile.ini can be
+used for building lndir the first time. You may have to specify
+OSFLAGS=-Dsomething to get it to compile. What you would pass as
+BOOTSTRAPCFLAGS might work. The command line looks something like this:
+
+ make -f Makefile.ini OSFLAGS=-Dflag
+
+
+To use a symbolic link tree, create a directory for the build, cd to it,
+and type this:
+
+ lndir sourcedir
+
+
+where sourcedir is the pathname of the directory where you stored the
+sources. All of the build instructions given below should then be done
+in the build directory on each machine, rather than in the source direc-
+tory.
+
+xc/config/util/mkshadow/ contains mkshadow, an alternative program to
+lndir.
+
+
+2.5. Configuration Parameters
+
+
+Build information for each source directory is in files called
+Imakefile. An Imakefile, along with local configuration information in
+xc/config/cf/, is used by the program imake to generate a Makefile.
+
+Most of the configuration work prior to building the release is to set
+parameters so that imake will generate correct files. Most of those
+parameters are set in xc/config/cf/site.def. You will also need to
+check the appropriate vendor-specific .cf file in xc/config/cf/ to make
+sure that OSMajorVersion, OSMinorVersion, and OsTeenyVersion are set
+correctly for your system. Override them in site.def if necessary.
+
+The site.def file has two parts, one protected with "#ifdef BeforeVen-
+dorCF" and one with "#ifdef AfterVendorCF". The file is actually pro-
+cessed twice, once before the .cf file and once after. About the only
+thing you need to set in the "before" section is HasGcc2; just about
+everything else can be set in the "after" section.
+
+The sample site.def also has commented out support to include another
+file, host.def. This scheme may be useful if you want to set most
+parameters site-wide, but some parameters vary from machine to machine.
+If you use a symbolic link tree, you can share site.def across all
+machines, and give each machine its own copy of host.def.
+
+The config parameters are listed in xc/config/cf/README, but here are
+some of the more common parameters that you may wish to set in site.def.
+
+ProjectRoot
+ The destination where X will be installed. This variable needs to
+ be set before you build, as some programs that read files at run-
+ time have the installation directory compiled in to them. Assuming
+ you have set the variable to some value /path, files will be
+ installed into /path/bin, /path/include/X11, /path/lib, and
+ /path/man.
+
+HasGccSet to YES to build with gcc version 1.
+
+HasGcc2
+ Set to YES to build with gcc version 2. Both this option and
+ HasGcc look for a compiler named gcc, but HasGcc2 will cause the
+ build to use more features of gcc 2, such as the ability to compile
+ shared libraries.
+
+BuildXInputExt
+ Set to YES to build the X Input Extension. This extension requires
+ device-dependent support in the X server, which exists only in Xhp
+ in our implementation.
+
+BuildPexExt
+ Set to NO to not build the PEX server extension and fonts.
+
+DefaultUsrBin
+ This is a directory where programs will be found even if PATH is
+ not set in the environment. It is independent of ProjectRoot and
+ defaults to /usr/bin. It is used, for example, when connecting
+ from a remote system via rsh. The rstart program installs its
+ server in this directory.
+
+InstallServerSetUID
+ Some systems require the X server to run as root to access the dev-
+ ices it needs. If you are on such a system and will not be using
+ xdm, you can set this variable to YES to install the X server
+ setuid to root. Note that the X server has not been analyzed by
+ the X Consortium for security in such an installation; talk to your
+ system manager before setting this variable.
+
+InstallXdmConfig
+ By default set to NO, which suppresses installing xdm config files
+ over existing ones. Leave it set to NO if your site has customized
+ the files in /usr/X11R6.3/lib/X11/xdm, as many sites do. If you
+ don't install the new files, merge any changes present in the new
+ files.
+
+MotifBC
+ Causes Xlib and Xt to work around some bugs in older versions of
+ Motif. Set to YES only if you will be linking with Motif version
+ 1.1.1, 1.1.2, or 1.1.3.
+
+GetValuesBC
+ Setting this variable to YES allows illegal XtGetValues requests
+ with NULL ArgVal to usually succeed, as R5 did. Some applications
+ erroneously rely on this behavior. Support for this will be
+ removed in a future release.
+
+The following vendor-specific .cf files are in the release but have not
+been tested recently and hence probably need changes to work:
+apollo.cf, bsd.cf, convex.cf, DGUX.cf, luna.cf, macII.cf, Mips.cf,
+moto.cf, Oki.cf, pegasus.cf, x386.cf. Amoeba.cf is known to require
+additional patches.
+
+The file xc/lib/Xdmcp/Wraphelp.c, for XDM-AUTHORIZATION-1, is not
+included in this release.
+
+
+2.6. System Build Notes
+
+
+This section contains hints on building X with specific compilers and
+operating systems.
+
+If the build isn't finding things right, make sure you are using a com-
+piler for your operating system. For example, a pre-compiled gcc for a
+different OS will not have right symbols defined, so imake will not work
+correctly.
+
+
+2.6.1. gcc
+
+gcc version 2 is in regular use at the X Consortium on Sparc platforms.
+Set the variable HasGcc2. X will not compile on some systems with gcc
+version 2.5, 2.5.1, or 2.5.2 because of an incorrect declaration of mem-
+move() in a gcc include file.
+
+If you are using a gcc version older than 2.7 on Solaris x86, you need
+to specify BOOTSTRAPCFLAGS="-Dsun" in the "make World" command.
+
+
+2.6.2. Other GNU tools
+
+Use of the GNU assembler, as, or linker, ld, is not supported. GNU make
+is not supported.
+
+
+2.6.3. SparcWorks 2.0
+
+
+If you have a non-threaded program and want to debug it with the old
+SparcWorks 2.0 dbx, you will need to use the thread stubs library in
+xc/util/misc/thr_stubs.c. Compile it as follows:
+
+ cc -c thr_stubs.c
+ ar cq libthr_stubs.a thr_stubs.o
+ ranlib libthr_stubs.a
+
+Install libthr_stubs.a in the same directory with your X libraries
+(e.g., /usr/X11R6.3/lib/libthr_stubs.a). Add the following line to
+site.def:
+
+ #define ExtraLibraries -lsocket -lnsl $(CDEBUGFLAGS:-g=-lthr_stubs)
+
+This example uses a make macro substitution; not all make implementa-
+tions support this feature.
+
+
+2.6.4. CenterLine C under Solaris 2
+
+
+If you are using the CenterLine C compiler to compile the distribution
+under Solaris 2, place the following line in your site.def:
+
+ #define HasCenterLineC YES
+
+If clcc is not in your default search path, add this line to site.def:
+
+ #define CcCmd /path/to/your/clcc
+
+
+If you are using CodeCenter 4.0.4 or earlier, the following files
+trigger bugs in the clcc optimizer:
+
+ xc/programs/Xserver/cfb16/cfbgetsp.c
+ xc/programs/Xserver/cfb16/cfbfillsp.c
+ xc/programs/Xserver/cfb/cfbgetsp.c
+
+
+Thus to build the server, you will have to compile these files by hand
+with the -g flag:
+
+ % cd xc/programs/Xserver/cfb16
+ % make CDEBUGFLAGS="-g" cfbgetsp.o cfbfillsp.o
+ % cd ../cfb
+ % make CDEBUGFLAGS="-g" cfbgetsp.o
+
+This optimizer bug appears to be fixed in CodeCenter 4.0.6.
+
+
+2.6.5. IBM AIX 4.1.4
+
+
+On AIX 4.1.4, the file lib/font/Type1/objects.c must be compiled without
+optimization (-O) else the X server will exit when Type 1 fonts are
+used.
+
+
+2.6.6. SunOS 4
+
+
+SunOS 4.0 and earlier need BOOTSTRAPCFLAGS=-DNOSTDHDRS because they do
+not have unistd.h nor stdlib.h. Do not supply a BOOTSTRAPCFLAGS when
+building any SunOS 4.1 version.
+
+
+2.6.7. Microsoft Windows NT
+
+
+All of the base libraries are supported, including multi-threading in
+Xlib and Xt, but some of the more complicated applications, specifically
+xterm and xdm, are not supported.
+
+There are also some other rough edges in the implementation, such as
+lack of support for non-socket file descriptors as Xt alternate inputs
+and not using the registry for configurable parameters like the system
+filenames and search paths.
+
+The Xnest server has been made to run on NT. It requires a real X
+server for output still.
+
+
+2.6.8. Omron Luna
+
+
+The Omron Luna platform is no longer supported. The Luna version of the
+make program doesn't define the standard macro MAKE, so you must run it
+as "make MAKE=make" at top level, e.g., "make MAKE=make World".
+
+
+2.7. The Build
+
+
+On NT, type
+
+ nmake World.Win32 > world.log
+
+On other systems, find the BootstrapCFlags line, if any, in the vendor-
+specific .cf file. If there isn't one, type
+
+ % make World >& world.log
+
+otherwise type
+
+ % make World BOOTSTRAPCFLAGS="value" >& world.log
+
+
+You can call the output file something other than "world.log", but do
+not call it "make.log" because files with this name are automatically
+deleted during the "cleaning" stage of the build.
+
+Because the build can take several hours to complete, you will probably
+want to run it in the background and keep a watch on the output. For
+example:
+
+ % make World >& world.log &
+ % tail -f world.log
+
+
+If something goes wrong, the easiest thing is to just start over (typing
+"make World" again) once you have corrected the problem.
+
+
+2.8. Installing X
+
+
+If everything is built successfully, you can install the software by
+typing the following as root:
+
+ % make install >& install.log
+
+
+Again, you might want to run this in the background and use tail to
+watch the progress.
+
+You can install the manual pages by typing the following as root:
+
+ % make install.man >& man.log
+
+
+
+2.8.1. System Installation Notes
+
+
+This section contains hints on installing and using X with specific com-
+pilers and operating systems.
+
+
+2.8.1.1. The X Server on AIX 4
+
+
+For IBM's AIX 4, you need to make sure the LFT device is associated with
+the correct graphics adapter. It's a one-time setup that does not hap-
+pen automatically, even if there's only one graphics adapter in the sys-
+tem. To configure the LFT device properly, become root and start SMIT.
+Go to the "Devices" category, choose "LFT", then "Displays", then "Move
+the LFT to Another Display".
+
+Select "Both" for when the change should take effect, then select the
+display adapter where you want to run the X server. Confirm the changes
+and exit SMIT; from now on, you should be able to run the server just
+fine.
+
+To run Xibm from xdm, you must provide the "-force" flag on the server
+command line in the Xservers file.
+
+
+2.9. Shared Libraries
+
+
+The version number of some of the the shared libraries has been changed.
+On SunOS 4, which supports minor version numbers for shared libraries,
+programs linked with the R6 libraries will use the new libraries with no
+special action required. On other platforms you have the following
+choices:
+
+1. Keep the old versions of the libraries around.
+
+2. Relink all applications with the new libraries.
+
+3. Create a link from the old name to the new name.
+
+ For example, to have programs that were linked against
+ libX11.so.6.0 use libX11.so.6.3, make this link:
+
+ ln -s libX11.so.6.3 libX11.so.6.0
+
+
+
+2.10. Setting Up xterm
+
+
+If your /etc/termcap and /usr/lib/terminfo databases do not have correct
+entries for xterm, use the sample entries provided in the directory
+xc/programs/xterm/. System V users may need to compile and install the
+terminfo entry with the tic utility.
+
+Since each xterm will need a separate pseudoterminal, you need a reason-
+able number of them for normal execution. You probably will want at
+least 32 on a small, multiuser system. On most systems, each pty has
+two devices, a master and a slave, which are usually named
+/dev/tty[pqrstu][0-f] and /dev/pty[pqrstu][0-f]. If you don't have at
+least the "p" and "q" sets configured (try typing "ls /dev/?ty??"), you
+should have your system administrator add them. This is commonly done
+by running the MAKEDEV script in the /dev directory with appropriate ar-
+guments.
+
+
+2.11. Starting Servers at System Boot
+
+
+The xfs and xdm programs are designed to be run automatically at system
+startup. Please read the manual pages for details on setting up confi-
+guration files; reasonable sample files are in xc/programs/xdm/config/
+and xc/programs/xfs/.
+
+
+2.11.1. On BSD-based systems using /etc/rc
+
+
+If your system uses an /etc/rc file at boot time, you can usually enable
+these programs by placing the following at or near the end of the file:
+
+ if [ -f /usr/X11R6.3/bin/xfs ]; then
+ /usr/X11R6.3/bin/xfs & echo -n ' xfs'
+ fi
+
+ if [ -f /usr/X11R6.3/bin/xdm ]; then
+ /usr/X11R6.3/bin/xdm; echo -n ' xdm'
+ fi
+
+
+Since xfs can serve fonts over the network, you do not need to run a
+font server on every machine with an X display. You should start xfs
+before xdm, since xdm may start an X server which is a client of the
+font server.
+
+The examples here use /usr/X11R6.3/bin, but if you have installed into a
+different directory by setting (or unsetting) ProjectRoot then you need
+to substitute the correct directory.
+
+If you are unsure about how system boot works, or if your system does
+not use /etc/rc, consult your system administrator for help.
+
+
+2.11.2. On SystemV-based systems
+
+
+There are two ways you can get On systems with a /etc/inittab file, you
+can edit this file to add the lines
+
+ xfs:3:once:/usr/X11R6.3/bin/xfs
+ xdm:3:once:/usr/X11R6.3/bin/xdm
+
+
+On some systems, you can edit a file in /etc/init.d to run the X Consor-
+tium xdm instead of the vendor's product xdm. On Sony this file is
+/etc/init.d/consxdm. On IRIX edit /etc/init.d/xdm.
+
+
+2.12. Using OPEN LOOK applications
+
+
+You can use the X11R6 Xsun server with OPEN LOOK applications, but you
+must pass the -swapLkeys flag to the server on startup, or the OPEN LOOK
+Undo, Copy, Paste, Find, and Cut keys may not work correctly. For exam-
+ple, to run Sun's OpenWindows 3.3 desktop environment with an X11R6
+server, use the command:
+
+ % openwin -server /usr/X11R6.3/bin/Xsun -swapLkeys
+
+
+The keysyms reported by keys on the numeric keypad have also changed
+since X11R5; if you find that OpenWindows applications do not respond to
+keypad keys and cursor control keys when using the R6 server, you can
+remap the keypad to generate R5 style keysyms using the following xmod-
+map commands:
+
+ keysym Pause = F21
+ keysym Print = F22
+ keysym Break = F23
+ keysym KP_Equal = F24
+ keysym KP_Divide = F25
+ keysym KP_Multiply = F26
+ keysym KP_Home = F27
+ keysym KP_Up = Up
+ keysym KP_Prior = F29
+ keysym KP_Left = Left
+ keycode 100 = F31
+ keysym KP_Right = Right
+ keysym KP_End = F33
+ keysym KP_Down = Down
+ keysym KP_Next = F35
+ keysym KP_Insert = Insert
+ keysym KP_Delete = Delete
+
+
+
+2.13. Rebuilding after Patches
+
+
+You shouldn't need this right away, but eventually you are probably go-
+ing to make changes to the sources, for example by applying any public
+patches that may be released.
+
+Each patch comes with explicit instructions at the top of it saying what
+to do. Thus the procedure here is only an overview of the types of com-
+mands that might be necessary to rebuild X after changing it.
+
+If you are building from CD-ROM, apply the patches to the symbolic link
+tree. The links to changed files will be replaced with local files con-
+taining the new contents.
+
+If only source files are changed, you should be able to rebuild just by
+going to the xc directory in your build tree and typing:
+
+ % make >& make.log
+
+
+If configuration files are changed, the safest thing to do is type:
+
+ % make Everything >& every.log
+
+
+"Everything" is similar to "World" in that it rebuilds every Makefile,
+but unlike "World" it does not delete the existing objects, libraries,
+and executables, and only rebuilds what is out of date.
+
+
+2.14. Formatting the Documentation
+
+
+The PostScript files in xc/doc/hardcopy can be generated from the
+sources in xc/doc/specs. Most of the documentation is in troff using
+the -ms macros. The easiest way to format it is to use the Imakefiles
+provided.
+
+Set the name of your local troff program by setting the variable
+TroffCmd in xc/config/cf/site.def. Then build the Makefiles:
+
+ cd xc/doc
+ make SUBDIRS=specs Makefiles
+
+
+Finally, go to the directory you are interested in and type "make"
+there. This command will generate .PS files. You can also generate
+text files by specifying the document name with a .txt extension as a
+make target, e.g., "make icccm.txt".

+=======================
+Xvnc - the VNC X server
+=======================
+
+This is the top level directory for Xvnc, the VNC X server (or the X VNC
+server, depending on how you look at it).
+
+It is based on the XFree86 3.3.2 "server only" distribution, which in turn is
+based on the X11R6.3 distribution from the X consortium.
+
+To build Xvnc, simply do "make World" in this directory (make sure you have run
+./configure in the directory above this one first - this generates the file
+config/cf/vnclibs.def which is needed for the build). If the build is
+successful, the binary will be left in programs/Xserver.
+
+If you have trouble building you may need to play around with the imake
+configuration files in the directory config/cf. Read the X consortium files
+RELNOTES.TXT and INSTALL.TXT. Also see the file config/cf/vnc.def for
+information specific to Xvnc.
+
+The code specific to the VNC X server is in programs/Xserver/hw/vnc. The rest
+of the code is a cut-down version of the standard XFree86 distribution without
+many of the later X extensions or hardware-specific code.

+
+
+
+1. What Is Release 6.3
+
+
+This is the last X Consortium implementation of the X Window System. X
+is a vendor-neutral, system-architecture neutral network-transparent
+window system and user interface standard. X runs on a wide range of
+computing and graphics machines. For an overview of X, see the X manual
+page.
+
+R6.3 is an update to R6.1. It is compatible with R6 and R6.1 at the
+source and protocol levels in all respects, and binaries are upward-
+compatible.
+
+What about Release 6.2? Release 6.2 is a proper subset of Release 6.3
+produced at the request of the OSF Common Desktop Environment program.
+It was produced by the X Consortium and is being released by OSF simul-
+taneously with CDE 2.1. Release 6.2 contains only the print extension
+and the Xlib implementation of vertical writing and user-defined charac-
+ter support.
+
+The X Consortium was an independent, not-for-profit membership corpora-
+tion formed in 1993 as the successor to the MIT X Consortium and dis-
+solved at the end of 1996. Refer to the Consortium man page for addi-
+tional details about the X Consortium.
+
+See xc/INSTALL.PS (PostScript) or xc/INSTALL.TXT (plain text) for
+instructions on how to build and install this software.
+
+
+1.1. Overview of the X Consortium Release
+
+
+The X Consortium software and documentation in Release 6.3 is in direc-
+tory xc/ and contains the following:
+
+X Consortium Standards
+ The X Consortium produced standards: documents which define net-
+ work protocols, programming interfaces, and other aspects of the X
+ environment. See the XStandards manual page for a list of stan-
+ dards.
+
+Implementations
+ For most of our standards, we provide high-quality implementations
+ to demonstrate proof of concept and to give early adopters and ven-
+ dors a base to use. These are not reference implementations; the
+ written specifications define the standards.
+
+Fonts
+ A collection of bitmap and outline fonts are included in the dis-
+ tribution, contributed by various individuals and companies.
+
+Utility Libraries
+ A number of libraries, such as Xmu and the Athena Widget Set, are
+ included. These are not standards, but are used in building X Con-
+ sortium applications and may be useful in building other applica-
+ tions.
+
+Programs
+ We also provide a number of application programs. A few of these
+ programs, such as xdm (or its equivalent), should be considered
+ essential in almost all environments. The rest of the applications
+ carry no special status; they are simply programs that have been
+ developed and/or maintained by X Consortium staff. In some cases,
+ you will find better substitutes for these programs contributed by
+ others.
+
+
+1.2. Supported Systems
+
+
+We built and tested this release on the following systems:
+
+
+ AIX 4.2
+ Digital Unix 4.0A
+ HP-UX 10.01
+ IRIX 6.2
+ Solaris 2.5
+ UNIX System V/386 Release 4.2 (Novell UnixWare) Version 2.02
+
+We also built this release on the following and did some minimal test-
+ing:
+
+ FreeBSD 2.1.6
+ Linux 1.2.13 (Yggdrasil) and 2.0.0 (Slackware 3.1)
+ SCO Open Server 5.0
+ SunOS 4.1.4
+ Windows NT 4.0
+
+
+In all cases except SunOS we have used the vendor's compiler. On SunOS
+we build with gcc.
+
+
+1.2.1. Supported Display Devices
+
+
+This release includes the necessary device-dependent support to build a
+native X server for the following platforms:
+
+ XFree86: See the XF_* man pages for supported video cards
+
+ AIX: Xibm with Skyway display adapter
+ HP-UX: Xhp
+ Digital Unix: Xdec on Alpha AXP with PMAG-B frame buffer
+ SunOS/Solaris: Xsun -- see the Xsun man page for supported frame buffers
+ Ultrix[1] :Xdec
+
+In addition to the above, the Xvfb and Xnest servers can be built on
+most platforms.
+
+Native servers are not built on IRIX or Microsoft Windows NT.
+
+
+1.3. The XC Tree
+
+
+The general layout under xc/ is as follows:
+
+
+config/ config files, imake, makedepend, build utilities
+doc/ all documentation other than per-program manual pages
+fonts/ BDF, Speedo, Type1 fonts
+include/ include files shared by multiple directories
+lib/ all libraries
+nls/ national language support files
+programs/ all programs, including the X server and rgb
+util/ patch, compress, other utilities
+bug-report bug reporting template
+registry X Registry
+
+
+This file is xc/RELNOTES.*, in various formats. The documentation
+source files RELNOTES.ms and INSTALL.ms are in the xc/doc/misc/ direc-
+tory.
+
+
+1.4. X Registry
+
+
+The X Consortium maintained a registry of certain X-related items to aid
+in avoiding conflicts and to aid in sharing of such items.
+
+The registry is in the file xc/registry in the distribution. The latest
+version may also be available by sending a message to xstuff@x.org. The
+message can have a subject line and no body, or a single-line body and
+no subject; in either case the line should look like this:
+
+ send docs registry
+
+
+
+1.5. Extensions Supported
+
+
+The core distribution includes the following extensions: BIG-REQUESTS,
+DOUBLE-BUFFER, LBX, MIT-SHM, MIT-SUNDRY-NONSTANDARD, Multi-Buffering,
+RECORD, SECURITY, SHAPE, SYNC, X3D-PEX, XC-APPGROUP, XC-MISC, XFree86-
+VidModeExtension, XIE, XInputExtension, XKEYBOARD, XpExtension (print-
+ing), XTEST, and XTestExtension1.
+
+Not all of these extensions are standards; see the XStandards manual
+page. Some of these extensions are not supported on all platforms.
+
+
+1.6. Implementation Parameters
+
+
+Some of the specifications define some behavior as implementation-
+dependent. Implementations of X Consortium standards need to document
+how those parameters are implemented; this section does so.
+
+XFILESEARCHPATH default
+ This default can be set at build time by setting the imake vari-
+ ables XFileSearchPathDefault, XAppLoadDir, XFileSearchPathBase, and
+ ProjectRoot in site.def. See xc/config/cf/README for instructions
+ and xc/config/cf/X11.tmpl[2] for details of how these configuration
+ variables are used.
+
+ By default ProjectRoot is /usr/X11R6.3 and XFILESEARCHPATH has
+ these components:
+
+ /usr/X11R6.3/lib/X11/%L/%T/%N%C%S
+ /usr/X11R6.3/lib/X11/%l/%T/%N%C%S
+ /usr/X11R6.3/lib/X11/%T/%N%C%S
+ /usr/X11R6.3/lib/X11/%L/%T/%N%S
+ /usr/X11R6.3/lib/X11/%l/%T/%N%S
+ /usr/X11R6.3/lib/X11/%T/%N%S
+
+
+XUSERFILESEARCHPATH default
+ If the environment variable XAPPLRESDIR is defined, the default
+ value of XUSERFILESEARCHPATH has the following components:
+
+ $XAPPLRESDIR/%L/%N%C
+ $XAPPLRESDIR/%l/%N%C
+ $XAPPLRESDIR/%N%C
+ $HOME/%N%C
+ $XAPPLRESDIR/%L/%N
+ $XAPPLRESDIR/%l/%N
+ $XAPPLRESDIR/%N
+ $HOME/%N
+
+ Otherwise it has these components:
+
+ $HOME/%L/%N%C
+ $HOME/%l/%N%C
+ $HOME/%N%C
+ $HOME/%L/%N
+ $HOME/%l/%N
+ $HOME/%N
+
+
+XKEYSYMDB default
+ Defaults to /usr/X11R6.3/lib/X11/XKeysymDB, assuming ProjectRoot is
+ set to /usr/X11R6.3.
+
+XCMSDB default
+ Defaults to /usr/X11R6.3/lib/X11/Xcms.txt, assuming ProjectRoot is
+ set to /usr/X11R6.3.
+
+XLOCALEDIR default
+ Defaults to the directory /usr/X11R6.3/lib/X11/locale, assuming
+ ProjectRoot is set to /usr/X11R6.3. The XLOCALEDIR variable can
+ contain multiple colon-separated pathnames.
+
+XErrorDB location
+ The Xlib error database file is /usr/X11R6.3/lib/X11/XErrorDB,
+ assuming ProjectRoot is set to /usr/X11R6.3.
+
+XtErrorDB location
+ The Xt error database file is /usr/X11R6.3/lib/X11/XtErrorDB,
+ assuming ProjectRoot is set to /usr/X11R6.3.
+
+Supported Locales
+ X locales supported are in locale.dir; the mapping between various
+ system locale names and X locale names is in locale.alias. Both
+ files are shipped in the xc/nls/X11/locale/ directory and installed
+ in the XLocaleDir directory (e.g. /usr/X11R6.3/lib/X11/locale/).
+
+Input Methods supported
+ The core distribution does not include any input method servers.
+ However, Xlib supplies a default built-in input method that sup-
+ ports compose processing in 8-bit locales. Compose files are pro-
+ vided for Latin-1 and Latin-2. The built-in input method can sup-
+ port other locales, given suitable compose files. See
+ xc/nls/X11/locale/Compose/iso8859-* for the supported compositions.
+
+There are input method servers available on the net.
+
+
+
+2. What is Unchanged in Release 6.3
+
+
+As this is an update release, there is a great deal of stability in the
+standards, libraries, and clients. No existing standards other than the
+ICE library specification have changed in a material way, though several
+documents have been updated with editorial improvements. There is one
+new interface added to the ICE library libICE; see below. The extension
+library, libXext, is updated to include the LBX, security, and applica-
+tion group extension interfaces. All previous interfaces in these and
+all other libraries are unchanged.
+
+
+
+3. What Is New in Release 6.3
+
+
+This section describes changes in the X Consortium distribution since
+Release 6.1.
+
+All libraries, protocols, and servers are compatible with Release 6 and
+Release 6.1. That is, R6 and R6.1 clients and applications will work
+with R6.3 libraries and servers. Most R6.3 clients will work with R6.1
+and R6 libraries except those that use the new interfaces in libICE,
+libXext, and libXp.
+
+The major new functionality in R6.3 is support for World Wide Web
+integration, protection of data from ``untrusted'' client connections, a
+bandwidth- and latency-optimized protocol for using X across the Inter-
+net, a print protocol following the Xlib API, and support for vertical
+text writing and user-defined characters in the Xlib implementation.
+
+
+3.1. OS Support
+
+
+The following platforms have a newer operating system version supported:
+
+
+System R6.1 R6.3
+
+AIX 4.1.4 4.2
+Digital Unix 3.2C 4.0A
+HP-UX 10.01
+IRIX 5.3 6.2
+Solaris 2.4 2.5
+UnixWare 2.02
+
+
+We also built on the following platforms, however full support is not
+guaranteed:
+
+
+System R6.1 R6.3
+
+FreeBSD 2.1.0 2.1.6
+Linux 1.2.13 2.0
+SCO Open Server 5.0
+SunOS 4.1.3 4.1.4
+Windows NT 3.5 4.0
+
+
+
+3.2. New Standards
+
+
+The following are new X Consortium standards in Release 6.3. Each is
+described in its own section below.
+
+ Low Bandwidth X Extension
+ RX: X Remote Execution MIME type
+ Security Extension
+ Application Group Extension
+ Print Extension
+ Proxy Management Protocol
+
+
+
+3.3. Low Bandwidth X Extension
+
+
+The Low Bandwidth X extension (LBX) defines several compression and
+local caching techniques to improve performance on wide area networks
+and also on slower-speed connections. These reduce the amount of proto-
+col data transported over the network and reduce the number of client-
+to-server roundtrips required for common application startup operations.
+
+LBX was referred to as X.fast in some materials but we elected to not go
+through the implementation and change all the names. To avoid any con-
+fusion with an external name different from the internal name in the
+implementation, we elected to drop the ``X.fast'' moniker.
+
+LBX is implemented in two pieces; an X server extension and a proxy
+application. The X server extension provides the new optimized proto-
+col. The proxy application, lbxproxy, translates a normal client X pro-
+tocol stream into an LBX stream. This permits any existing application
+to gain the benefit of the optimized protocol with no changes. The
+proxy is especially useful when multiple applications are running on the
+same local area network separated from the X server by a slower network.
+In this case the full benefit of the local cache is shared by each
+application using the same proxy process.
+
+The specification for LBX is in xc/doc/specs/Xext/lbx.mif (FrameMaker
+interchange source) and xc/doc/hardcopy/Xext/lbx.PS.Z (compressed
+PostScript).
+
+
+3.4. RX: X Remote eXecution
+
+
+The remote execution (RX) service specifies a MIME format for invoking
+applications remotely, for example via a World Wide Web browser. This
+RX format specifies a syntax for listing network services required by
+the application, for example an X display server. The requesting Web
+browser must identify specific instances of the services in the request
+to invoke the application.
+
+The distribution contains a helper program (xrx) and a Netscape Naviga-
+tor plug-in (libxrx) that demonstrate this protocol. The plug-in
+requires Navigator 3.0.
+
+We have only been able to test the plug-in on HP-UX, IRIX, Digital Unix,
+and Solaris2. Netscape Navigator binaries for other platforms are
+either not available at all or were not available in time to be included
+in the testing for this release.
+
+The specification for the RX mime type is in xc/doc/specs/RX/RX.mif
+(FrameMaker interchange source) and xc/doc/hardcopy/RX/RX.PS.Z
+(compressed PostScript).
+
+The following section describes the procedure to set up your environment
+and try the examples provided in this distribution.
+
+
+3.4.1. Preparing Your Web Server
+
+
+In order to demonstrate the RX helper program and the RX Netscape plug-
+in you need to have access to an HTTP server to install ``common gateway
+interface'' (CGI) scripts. While CGI programs can be written in any
+compiled or interpreted language, the sample CGI programs in the distri-
+bution are written in perl.
+
+If you don't currently have a web server the NCSA server is a good one
+to try. Binaries for various systems are available at:
+
+ http://hoohoo.ncsa.uiuc.edu/docs/setup/PreExec.html
+
+If you don't have perl you can get the source code from:
+ ftp://prep.ai.mit.edu/pub/gnu/perl-4.036.tar.gz
+
+You need to install the HTML, RX, and CGI sample files into your
+server's HTML and CGI directories. The process can be partially
+automated by adding the following definitions to your site.def or
+host.def file:
+
+
+WebServer defines the hostname and port of your web server, for
+ example
+
+ #define WebServer www.myorg.org:8001
+
+HtmlDir defines the path at which HTML and RX documents are
+ installed, for example
+
+ #define HtmlDir /usr/local/etc/httpd/htdocs
+
+CgiBinDir defines the path at which CGI programs are installed, for
+ example
+
+ #define CgiBinDir /usr/local/etc/httpd/cgi-bin
+
+ProxyManager defines the transport scheme, hostname, and port for CGI
+ programs to contact the Proxy Manager. See the proxymngr
+ man pages for further details. Typically the proxy
+ manager host will be the same as your web server, for
+ example:
+
+ #define ProxyManager tcp/www.myorg.org:6500
+
+Then make the Makefiles and build the directories with the following
+command sequence:
+
+cd xc/programs/xrx/htdocs
+xmkmf ../../.. programs/xrx/htdocs
+make
+make install
+cd ../cgi-bin
+xmkmf ../../.. programs/xrx/cgi-bin
+make
+make install
+
+
+These directories are not automatically built or installed by the top
+level Makefile because they install outside the ProjectRoot.
+
+You also need to configure your web server so that files with the exten-
+sion name ``rx'' are of the MIME type ``application/x-rx''. See your
+HTTP server's configuration documentation for the right procedure to do
+so.
+
+
+3.4.2. The RX Helper Program
+
+
+The helper program, xrx, may be used with any Web browser to interpret
+the new RX document type.
+
+The RX helper program is installed in <ProjectRoot>/bin (e.g.
+/usr/X11R6.3/bin/). You will need to configure your web browser to use
+it for RX documents by adding a line to your $HOME/.mailcap:
+
+ application/x-rx; /X11/bin/xrx %s
+
+You may need to refer to your web browser's documentation for exact
+instructions on configuring helper applications.
+
+The helper program is activated by your browser as soon as you retrieve
+any document of the MIME type application/x-rx. All you need to do is to
+point your browser at the URL:
+ http://your.web.server/xload.rx
+
+The application (i.e. xload) should appear on your DISPLAY as a new
+top-level client. The client will be running on your web server host
+and connected to your X server. If your X server supports the SECURITY
+extension the client will be running as an untrusted client.
+
+
+3.4.3. The RX Netscape Navigator Plug-in
+
+
+The Navigator plug-in supports all the functions of xrx and in addition
+uses the new XC-APPGROUP extension, if your X server provides it, to
+cause the remotely launched application to be embedded within the
+browser page from which it was launched.
+
+The HTML page links to an RX document via the EMBED tag, a Netscape
+extension to HTML. The RX document provides the plug-in with the list
+of services the application wants to use. Based on this information,
+the plug-in sets the various requested services, including creating
+authorization keys, and passes the relevant data to the application
+through an HTTP GET request of the associated CGI script. The Web
+server then executes the CGI script to start the application.
+
+To be able to use the RX plug-in you need Netscape Navigator 3.0.
+Binaries for various systems can be found at:
+
+ http://home.netscape.com/comprod/mirror/client_download.html
+
+To complete the installation of the Netscape plug-in, find the file
+named libxrx.so.6.3 or libxrx.sl.6.3 (or similar, depending on your
+platform) in <ProjectRoot>/lib (e.g. /usr/X11R6.3/lib) and copy it to
+either /usr/local/lib/netscape/plugins or $HOME/.netscape/plugins. Do
+not install the symlinks libxrx.so or libxrx.sl; they may confuse
+Netscape.
+
+You should remove or comment out the line you may have previously added
+in your mailcap file to use the RX helper program, otherwise the plug-in
+will not be enabled. (The usual comment character for mailcap is
+``#''.)
+
+If you are already running Netscape Navigator, you need to exit and res-
+tart it after copying the plug-in library so the new plug-in will be
+found. Once this is done you can check that Navigator has successfully
+loaded the plug-in by checking the ``About Plug-ins'' page from the Help
+menu. This should show something like:
+
+
+ RX Plug-in
+
+ File name: /usr/guest/netscape/plugins/libxrx.sl.6.3
+
+ X Remote Activation Plug-in
+
+ Mime Type Description Suffixes Enabled
+ application/x-rx X Remote Activation Plug-inxrxYes
+
+
+The plug-in will be activated by Netscape Navigator as soon as you
+retrieve any document of the MIME type application/x-rx. Several sam-
+ples are included in the distribution. The most basic one is xload. All
+you need to do is point your browser at the page:
+ http://your.web.server/xload.html
+
+If something goes wrong check on the all the previous steps listed above
+and try again. Once xload is working you can try some of the other
+examples in the distribution such as bitmap.html or dtcm.html.

+
+3.4.4. Trying Embedding With an Old X Server
+
+
+The Netscape Navigator plug-in, libxrx, will work with an X server that
+does not contain the application group or security extensions. The
+application will be started as a separate top-level client.
+
+If you wish to try out the embedding facilities without replacing your
+desktop X server, you may use the Xnest server.
+
+A typical Xnest session would look like the following:
+
+% Xnest :11
+% xterm -display :11
+
+
+These two commands start a ``nested'' server and a terminal emulator
+within that server. Your favorite window manager and Netscape Navigator
+can now be executed from the nested xterm window. You may wish to first
+disable access control in the nested server by running ``xhost +'' in
+the nested xterm.
+
+
+3.4.5. Setting Up Your Own Applications To Run Over The Web
+
+
+Based on the examples provided in the distribution it should be easy to
+set up your web server to run your own applications. Every application
+requires 3 additional files to identify it to Web browsers:
+
+myapp.htmlAn HTML page to present the application embedded
+myapp.rx The RX document describing the application
+myapp.pl The CGI script to start the application
+
+Note that the separate ``.rx'' file could be omitted by implementing the
+CGI script such that if it is invoked without a QUERY_STRING it will
+return the RX content. We decided not to do so in the distributed exam-
+ples for purpose of clarity.
+
+The xload demo provides a good starting point. Simply make a copy of
+each of the files xload.rx, xload.html, and xload.pl. Then look inside
+them for every instance of ``xload'' and change it to whatever is
+appropriate for your application.
+
+You will not be able to run the dtcm demo unless you have dtcm (a CDE
+component) installed on your web server host. This example shows how a
+CGI script would look when an X Print server is requested. The script
+dtcm.pl is, for that reason, slightly more complicated than other exam-
+ples.
+
+
+3.5. Security Extension
+
+
+The SECURITY extension contains new protocol needed to provide enhanced
+X server security. This extension adds to the X protocol the concepts
+of ``trusted'' and ``untrusted'' clients. The trust status of a client
+is determined by the authorization used at connection setup. All
+clients using host-based authorization are considered ``trusted''.
+Clients using other authorization protocols may be either trusted or
+untrusted depending on the data included in the connection authorization
+phase.
+
+The requests in the security extension permit a trusted client to create
+multiple authorization entries for a single authorization protocol.
+Each entry is tagged with the trust status to be associated with any
+client presenting that authorization.
+
+When a connection identifying an ``untrusted'' client is accepted, the
+client is restricted from performing certain operations that would steal
+or modify data that is held by the server for trusted clients. An
+untrusted client performing a disallowed operation will receive protocol
+errors. Such a client may be written to catch these errors and continue
+operation.
+
+When a client is untrusted, the server will also limit the extensions
+that are available to the client. Each X protocol extension is respon-
+sible for defining what operations are permitted to untrusted clients;
+by default, the entire extension is hidden.
+
+The specification for the SECURITY extension is in
+xc/doc/specs/Xext/security.tex (LaTeX source) and
+xc/doc/hardcopy/Xext/security.PS.Z (compressed PostScript).
+
+
+3.5.1. Untrusted Application Behavior
+
+
+Most applications work normally when run as untrusted clients, but since
+the security extension changes the semantics of certain parts of the X
+protocol, it is no surprise that some clients behave differently when
+untrusted. We note the following significant behavior changes,
+separated into two categories: changes that we expect could disappear or
+mutate if the implementation were improved in a future release, and
+changes we expect are permanent, legitimate defenses against data loss
+or leakage.
+
+
+3.5.1.1. Behaviors That Are Implementation-Dependent
+
+
+The following behaviors when running the respective applications as
+untrusted are not mandated by the security design but are side effects
+of limitations in the current implementation.
+
+oclock is square because the SHAPE extension hasn't been marked secure
+yet. Similarly, Xaw applications that use oval buttons will have rec-
+tangular buttons instead.
+
+Any application that depends on an extension other than XC-MISC, LBX, or
+BIG-REQUESTS will have different behavior, as no other extensions are
+currently marked secure. The core clients affected are xieperf and all
+the xkb utilities.
+
+emacs exits with a Window error when trying to use the QueryPointer
+request on the root window when you click in a buffer.
+
+FrameMaker, and xwd -root both exit with a Window error when trying to
+use the GetWindowAttributes request on a window manager frame window.
+
+All the remaining changes are involved in some way with window proper-
+ties. Some of these behaviors can be modified with changes to the Secu-
+rityPolicy file; see the Xserver man page.
+
+Several clients exit with a Window error when trying to use the
+DeleteProperty request on various properties on the root window. These
+include xcmsdb -remove, xprop -root -remove, and xstdcmap -delete.
+
+xprop exits with an Atom error when attempting to access protected pro-
+perties.
+
+The following two changes require, in addition, a ``trusted selection
+intermediary'' to provide selection transfer from untrusted to trusted
+clients (and vice-versa). R6.3 does not include such a trusted
+intermediary.
+
+xterm exits with an Atom error when it tries to store the property value
+during a selection transfer (paste) to a trusted selection requester.
+
+The ``copy 0 to PRIMARY'' button of xcutsel does not work.
+
+Selection transfer from untrusted clients to trusted clients fails when
+the untrusted client attempts to use SendEvent to generate the Selec-
+tionNotify event for the requester. Most requesters will treat this as
+a transfer timeout and continue. Xt-based applications will create an
+additional Atom each time such a transfer is attempted.
+
+
+3.5.1.2. Behaviors That Are Not Likely To Change
+
+
+The following behaviors represent actions performed by the applications
+that are disallowed by design.
+
+editres will fail when pointed at a trusted client when it tries to read
+window properties on a window owned by that client.
+
+Xnest exits on startup with an Access error as it tries to use the
+ChangeKeyboardControl request.
+
+The new generate option to xauth fails because untrusted applications
+are not allowed to create additional authorizations.
+
+xhost cannot be used to modify the host access list.
+
+xmag gets an unending stream of Drawable errors as it tries to use the
+PolyRectangle request on the root window. If you click to select a
+location to magnify, xmag gets a Drawable error as it tries to use the
+GetImage request on the root window. xmag could be modified to exit
+gracefully under these conditions.
+
+netscape exits on startup with a Drawable error when trying to use the
+GetImage request on the root window.
+
+xmodmap exits with an Access error when trying to use the ChangeKey-
+boardMapping request.
+
+xset with the b, c, led, or r options exits with an Access error when
+trying to use the ChangeKeyboardControl request. With the bc option, it
+can't find the MIT-SUNDRY-NONSTANDARD extension and exits gracefully.
+
+xsetroot exits with a Window error when trying to use the ChangeWin-
+dowAttributes request on the root window.
+
+
+3.6. Application Group Extension
+
+
+The application group extension (XC-APPGROUP) provides new protocol to
+implement Application Groups (``AppGroups''). The AppGroup facility
+allows other clients to share the SubstructureRedirect mechanism with
+the window manager. This allows another client called the ``application
+group leader'', such as a web browser, to intercept a MapRequest made by
+a third application and reparent its window into the web browser before
+the window manager takes control. The AppGroup leader may also limit
+the screens and visuals available to the applications in the group.
+
+Users who have an XC-APPGROUP enhanced X server and an RX plug-in for
+their Netscape Navigator web browser can run programs remotely over the
+web and have the output appear as part of the presentation in their web
+browser.
+
+The only way for an application to become a member of an AppGroup is by
+using an authorization generated using the new security extension.
+Whenever an application connects to the server, the authorization that
+it used to connect is tested to see if it belongs to an AppGroup. This
+means that the Authorization data must be transmitted to the remote host
+where the application will be run. In the case of RX, HTTP is used to
+send the Authorization. Sites who have concerns about sending unen-
+crypted authorization data such as MIT-MAGIC-COOKIE-1 via HTTP should
+configure their web servers and web browsers to use SHTTP or SSL.
+
+The specification for the XC-APPGROUP extension is in
+xc/doc/specs/Xext/AppGroup.mif (FrameMaker interchange source) and
+xc/doc/hardcopy/Xext/AppGroup.PS.Z (compressed PostScript).
+
+
+3.7. Print Extension
+
+
+The print extension supports output to hardcopy devices using the core X
+drawing requests. The print extension adds requests for job and page
+control and defines how specific printer attributes are communicated
+between the server and printing clients. Printer attribute specifica-
+tions are modeled after the ISO 10175 specification.
+
+An X client that wants to produce hardcopy output will typically open a
+second connection to an X print server, produce a print job, and then
+close the print server connection. The print server may be the same
+process as the display server (the term ``video server'' is sometimes
+used) although the implementation provided in R6.3 does not completely
+support video and print servers in the same binary.
+
+The specification for the print extension is in
+xc/doc/specs/XPRINT/xp_proto.mif (FrameMaker interchange source) and
+xc/doc/hardcopy/XPRINT/xp_proto.PS.Z (compressed PostScript). The
+library API specification is in xc/doc/specs/XPRINT/xp_library.mif
+(FrameMaker interchange source) and
+xc/doc/hardcopy/XPRINT/xp_library.PS.Z (compressed PostScript).
+
+
+3.7.1. Running an X Print Server
+
+
+The print server is simply an X server with the print extension and spe-
+cial DDX implementations. The X Print Server is started like any other
+X server.
+
+Here is a sample command line for use with a typical configuration:
+
+% Xprt :1 -ac
+
+
+The options used in the example are:
+
+:1 On a host that is running a video display server you will need
+ to specify a different display from the default.
+
+-ac Disable access control, since no simple mechanism for sharing
+ keys is provided.
+
+The X print server supports the following additional options:
+
+-XpFile Points to the directory containing the print server configura-
+ tion files.
+
+XPCONFIGDIREnvironment variable specifying alternative location of the
+ print server configuration files.
+
+The print server, Xprt, is built only if the config option XprtServer is
+YES. Four printer DDXen are provided, each with a separate config
+option to control whether or not it will be included: XpRasterDDX,
+XpColorPclDDX, XpMonoPclDDX, XpPostScriptDDX; see xc/config/cf/README.
+XprtServer defaults to the value of BuildServer (i.e. Xprt will be built
+by default on all platforms that build a full X server). XpRasterDDX
+and XpMonoPclDDX default to NO. XpColorPclDDX and XpPostScriptDDX
+default to YES.
+
+The print server is configured through a directory of configuration
+files that define printer model types and instances of printer models.
+An example configuration tree is provided in
+xc/programs/Xserver/XpConfig/. See also xc/doc/specs/Xserver/Xprt.mif
+(FrameMaker interchange source) and xc/doc/hardcopy/Xserver/Xprt.PS.Z
+(compressed PostScript) for further instructions on configuring Xprt.
+
+
+3.7.2. Specifying The Print Server To A Client
+
+
+By convention, clients locate the print server using the environment
+variable XPRINTER. The syntax of XPRINTER is an augmented DISPLAY; i.e.
+
+ printerName@host:display
+
+where ``printerName'' is one of the printer instances listed in the
+print server configuration files. The use of XPRINTER and its syntax is
+an application convention only; there is nothing in the supplied
+libraries that uses (or parses) this environment variable.
+
+
+3.8. Proxy Management Protocol
+
+
+The Proxy Management Protocol is an ICE based protocol that provides a
+way for application servers to easily locate proxy services such as the
+LBX proxy and the X firewall proxy.
+
+Typically, a service called a ``proxy manager'' is responsible for
+resolving requests for proxy services, starting new proxies when
+appropriate, and keeping track of all of the available proxy services.
+The proxy manager strives to reuse existing proxy processes whenever
+possible.
+
+The Proxy Management Protocol is described in xc/doc/specs/PM/PM_spec.
+
+
+3.9. Configuration
+
+
+As in R6.1, the top-level Makefile is no longer over-ridden by the first
+build. Instead a new file xmakefile is created. Thus is it not neces-
+sary to take any additional steps to reset the builds.
+
+The file xc/config/cf/README provides more guidance on how to write an
+Imakefile, including a list of variables that may be set in an
+Imakefile. This file is strongly recommended reading for Imakefile
+authors.
+
+The LaTeX text processor is supported as of R6.1. If you have LaTeX on
+your system, turn on HasLatex to have the MakeLatexDoc rule use it.
+
+Also since R6.1, with System V Release 4 (SVR4) compilers we now use the
+-Xa (ANSI C with native extensions) compiler flag rather than -Xc (limit
+environment to that specified in the standard). This provides access to
+the full richness of the platform. Unfortunately, it also defines the
+preprocessor symbol __STDC__ to 0, instead of 1 as specified by the
+standard. Therefore we use "#ifdef __STDC__" in our sources rather than
+"#if __STDC__". On HP-UX systems we use the -Ae compiler option instead
+of -Aa, also to access the full environment offered by the platform.
+
+As in R6.1, the imake variables InstallXdmConfig, InstallXinitConfig,
+and InstallAppDefFiles suppress overwriting existing files; if the files
+didn't previously exist, the files are always installed. This interpre-
+tation makes bootstrapping a new system easier than in R6 and earlier
+releases.
+
+A new configuration build option, GzipFontCompression, has been added to
+use gzip rather than compress for font compression. It defaults to NO.
+
+The build creates a new directory xc/exports into which the header
+files, libraries, and certain build utility binaries are symlinked.
+This greatly simplifies Imakefile construction and supports multiple
+development projects (such as X, Motif, and CDE) on a single system.
+
+Imake rules and template files for building Motif and CDE were contri-
+buted by the OSF CDE/Motif project and are included in R6.3.
+
+
+3.10. Documentation
+
+
+Additional X server internals documentation is provided in the
+/xc/doc/specs/Xserver/ directory for the XC-APPGROUP and SECURITY exten-
+sions. An analysis and rationale for the SECURITY extension will also
+be found in that directory. Specifications for the other new standards
+are in /xc/doc/specs/RX/, /xc/doc/specs/XPRINT/, and
+/xc/doc/specs/Xext/.
+
+
+3.11. Header Files
+
+
+xc/include/Xos_r.h is a new header file to promote portable source code
+using thread-safe implementations of getpwnam, getpwuid, gethostbyname,
+gethostbyaddr, and getservbyname. It is not required by any X Consor-
+tium standard.
+
+
+3.12. X Server
+
+
+The security, LBX, printing, and AppGroup extensions are all new. In
+R6.3 only MIT-MAGIC-COOKIE-1 is supported in the security extension.
+Parts of the security policy are configured at run-time from the file
+/usr/X11R6.3/lib/X11/xserver/SecurityPolicy. Site-defined policy
+strings used by xfwp and rules for property access by untrusted clients
+are defined there. See the Xserver man page for full details.
+
+
+3.12.1. New Device Support
+
+
+Support has been added for the Sun TCX frame buffer as a dumb 8-bit
+frame buffer on Solaris 2.5.
+
+New XFree86 servers based on XFree86 3.2 are included.
+
+
+3.12.2. Internal Changes
+
+
+The security extension provides new internal resource ID lookup inter-
+faces that incorporate the access control lookup. In order to be
+declared secure and therefore be made available to untrusted clients,
+other extensions should, at a minimum, be changed to use these inter-
+faces. Depending on what the extension does, more may need to be done
+in its implementation before it can appropriately be labeled ``secure''.
+
+Refer to the documents xc/doc/specs/Xserver/appgroup.ms and
+xc/doc/specs/Xserver/secint.tex for implementation details of the appli-
+cation group and security extensions, respectively.
+
+
+3.13. ICE Library Addition
+
+
+To support proxy managers and firewall proxies using ICE on well-known
+TCP ports, an additional interface has been added to the ICE library.
+This new interface, IceListenForWellKnownConnections, has equivalent
+calling parameters to IceListenForConnections plus an ICE network id
+parameter.
+
+
+3.14. Xlib Vertical Writing and User-Defined Characters
+
+
+The Xlib output method implementation has been enhanced to support the
+XOM value drawing direction XOMOrientation_TTB_RTL. Vertical writing
+information and other locale specific information is read from the file
+<XLocaleDir>/%L/XLC_LOCALE where the XLocaleDir configuration option
+defaults to /usr/X11R6.3/lib/X11/locale.
+
+The X[mb|wc]TextEscapement functions now return the text escapement in
+pixels for the vertical or horizontal direction depending on the
+XNOrientation XOCValue.
+
+The X[mb|wc]DrawString functions will now render a character string in
+the vertical or horizontal direction depending on the XNOrientation
+XOCValue.
+
+The Xlib NLS database implementation has been enhanced to support
+extended segments used for interchanging non-standard code sets. Sup-
+port has been added for control sequences and encoding names used in
+extended segments and conversion of glyph indexes when interchanging
+data in extended segments.
+
+
+3.15. Xt Geometry Management Debugger
+
+
+Daniel Dardailler's ``GeoTattler'' code has been merged into the Xt
+Intrinsics library implementation. This is not a standard. If libXt is
+compiled with the XT_GEO_TATTLER symbol defined (currently there is no
+build configuration support to do this) then a ``geoTattler'' resource
+may be specified for any widget in an application. If the geoTattler
+resource for a widget instance is True then libXt will generate debug-
+ging information to stdout when the widget makes geometry change
+requests.
+
+For example, if the resources specify:
+
+myapp*draw.XmScale.geoTattler: ON
+*XmScrollBar.geoTattler:ON
+*XmRowColumn.exit_button.geoTattler:ON
+
+then geometry management debugging information will be generated for all
+the XmScale children of the widget named draw, all the XmScrollBars, and
+the widget named exit_button in any XmRowColumn.
+
+3.16. New Programs
+
+
+There are new core programs lbxproxy, proxymngr, xfindproxy, xfwp, Xprt,
+and xrx.
+
+
+lbxproxy The lbxproxy program is used to ``translate'' X protocol to
+ LBX protocol. It should be executed on the same host as the
+ client application or on a host connected to the client host
+ by a fast network. lbxproxy appears to the clients using it
+ as another X server; that is, the clients connect through it
+ using the conventional DISPLAY syntax, specifying the proxy
+ host in place of the server. lbxproxy can be used stand-
+ alone or in conjunction with proxymngr and xfindproxy. See
+ the lbxproxy man page for further details.
+
+proxymngr proxymngr is a process that runs continuously to control
+ other proxy applications, such as lbxproxy and xfwp. It
+ maintains a list of active proxy processes and responds to
+ queries from xfindproxy. See the proxymngr man pages for
+ further details.
+
+xfindproxy xfindproxy is used to locate a running proxy process for a
+ given network service, such as lbxproxy or xfwp, or to
+ request that a proxy be started if one is not already run-
+ ning. xfindproxy communicates with proxymngr to perform the
+ actual work.
+
+xfwp xfwp is the X firewall application proxy. It is designed to
+ run on a network firewall host and relay X protocol between
+ applications (typically outside the firewall) and the X
+ server (inside the firewall). xfwp appears to the clients
+ using it as another X server; that is, clients connect
+ through it using the conventional DISPLAY syntax. xfwp will
+ not do anything useful without proxymngr and xfindproxy or
+ xrx. See the xfwp man page for further details.
+
+Xprt Xprt is the print server, built as part of the Xserver build
+ if the XprtServer config option is YES. The print server
+ supports printing to PostScript and PCL devices, as well as
+ raster output to an xwd format file (and thence to any
+ printer that xpr supports). The print extension was
+ designed to be integrated with the ``video'' server in a
+ single process but the R6.3 implementation does not support
+ a combined video and print server. Details of configuration
+ for Xprt are in xc/doc/specs/Xserver/Xprt.mif (FrameMaker
+ interchange source) and xc/doc/hardcopy/Xserver/Xprt.PS.Z
+ (compressed PostScript).
+
+xrx, libxrx xrx is the Web browser helper application that interprets
+ documents in the RX MIME type to remotely launch applica-
+ tions via the Web. Its companion libxrx is a plug-in for
+ Netscape Navigator 3.0 that supports in addition the capa-
+ bility to visually embed the remote applications in the
+ associated browser Web page window. See the xrx man page
+ for further details.
+
+
+3.16.1. Using The LBX Proxy
+
+
+The implementation of lbxproxy provided here will support an arbitrary
+number of clients connecting to the same X server. A separate lbxproxy
+process is required for each separate X server process. A typical com-
+mand line to invoke lbxproxy is
+lbxproxy :22 -display myhost:0
+
+
+This command runs a proxy with the X server ``myhost:0'' as the target.
+Clients must connect to the proxy using ``proxyhost:22'' as the DISPLAY.
+The .Xauthority file for these clients must contain an entry for server
+``proxyhost:22'' with the same MIT-MAGIC-COOKIE as ``myhost:0'', or the
+X server must be configured to permit connections from any host on the
+network.
+
+Here is an example showing how to setup the appropriate .Xauthority
+entries:
+
+% lbxproxy :22 -display myws:0
+% xauth list
+myws:0 MIT-MAGIC-COOKIE-1 7fd231ccdce2
+myws/unix:0 MIT-MAGIC-COOKIE-1 7fd231ccdce2
+% xauth -f $HOME/proxyauth add proxyhost:22 . 7fd231ccdce2
+xauth: creating new authority file /usr/myself/proxyauth
+% xauth -f $HOME/proxyauth add proxyhost/unix:22 . 7fd231ccdce2
+% setenv XAUTHORITY $HOME/proxyauth
+
+
+In this example, the authorization token for display 0 is copied into a
+new file ``proxyauth'' and associated with the LBX proxy server display
+number (22). The new authority file may then be copied to another host
+and used as the value of the XAUTHORITY environment variable.
+
+The proxymngr daemon is usually configured to invoke lbxproxy automati-
+cally when a user or a CGI script runs xfindproxy -name LBX.
+
+See the lbxproxy man page for further details.
+
+
+3.17. Major Additions to Existing Programs
+
+
+The generate option of xauth is used to obtain additional authorization
+tokens for client connections. These authorization tokens may specify
+that the client using them is to be restricted in the operations that
+may be performed in the X server. The authorization tokens may be
+independently revoked. Refer to the SECURITY extension for further
+details on authorizations.
+
+The xauth man page gives full details on the new generate command. Here
+is an example use:
+
+xauth -f untrusted-auth-file g :0 . timeout 0
+setenv XAUTHORITY untrusted-auth-file
+
+This will cause xauth to contact server ``:0'' to get a long-lasting
+untrusted cookie which it then stores in untrusted-auth-file. By set-
+ting XAUTHORITY to point to untrusted-auth-file, subsequent applications
+run from this shell to server :0 will be untrusted. The ``g'' is short
+for ``generate'', and the ``.'' is short for ``MIT-MAGIC-COOKIE-1''. If
+you omit the -f argument, xauth will use $XAUTHORITY (or ~/.Xauthority),
+which may not be what you want, especially if you are creating an
+untrusted auth. This is because xauth will replace the trusted auth in
+~/.Xauthority (put there by xdm) with the untrusted one, preventing you
+from making any further trusted connections to the server.
+
+The xterm terminal emulator now supports the active icon mode that was
+in X version 10 Release 4. See the xterm man page for further details.
+There is support in the xterm source to build xterm without the active
+icon mode for those who may care for some reason to not provide it.
+
+
+3.18. ANSIfication
+
+
+As noted previously under "Configuration Files", for pragmatic reasons
+we changed the way we use __STDC__ to test for standard C compilers.
+R6.1 was officially the last release that supported traditional K&R C.
+R6.3 assumes a standard C compiler and environment. We have not inten-
+tionally removed any K&R C support from old code; most of the release
+will continue to build on older platforms.
+
+
+
+4. Known Bugs
+
+
+There are no examples in this release showing how to use the print
+extension. CDE 2.1 has several such applications.
+
+lbxproxy fails to start on SCO Open Server.
+
+x11perf running through lbxproxy will tickle a drawing bug in cfb-based
+X servers that causes some lines and curves to be drawn to the wrong
+coordinates and outside the window boundaries. Use the -nogfx option to
+lbxproxy as a workaround on affected servers.
+
+If proxymngr exits abnormally all managed proxies die.
+
+Documentation is missing on how to use the vertical writing and user-
+defined character support.
+
+Documentation is sparse on how to configure Xprt.
+
+There are no example fonts in the release with vertical text escapement
+(``vertical writing fonts'').

+hard to make this release a reality, and our thanks go out to them. You
+will find many of them listed in the acknowledgements in the individual
+specifications.
+
+Ken Raeburn of XFree86 and Cygnus Support contributed the gzip font
+compression support.
+
+The Common Desktop Environment sponsors Digital Equipment Corp, Fujitsu,
+Hewlett-Packard, Hitachi, IBM, Novell, and SunSoft jointly contributed
+the print extension and the Xlib vertical writing and user-defined char-
+acter support. Axel Deininger, Harry Phinney, Tom Gilg, Charles Prince,
+and Jim Miller all from Hewlett-Packard did the print extension and PCL
+and raster drivers. Fujitsu did the Xlib vertical writing and user-
+defined character support.

+
+ VERSION:
+
+R6.3, public-patch-2
+[X Consortium public patches edit this line to indicate the patch level]
+
+ CLIENT MACHINE and OPERATING SYSTEM:
+
+[e.g. Sparc/SunOS 5.3, DECstation 5000/Ultrix 4.3, HP 9000-730/HP-UX 9.1]
+
+ DISPLAY TYPE:
+
+[e.g. Sun GX, 8-bit framebuffer, IBM Skyway ...]
+
+ WINDOW MANAGER:
+
+[e.g. twm, mwm, gwm, olwm, ...]
+
+ COMPILER:
+
+[e.g. native ANSI cc, native cc, gcc 2.5.8, ...]
+
+ AREA:
+
+[Area of the source tree affected,
+e.g., Xserver, Xlib, Xt, Xaw, PEX, twm, xterm, xmh, config, ....
+Please only one area per bug report.]
+
+ SYNOPSIS:
+
+[Brief description of the problem and where it is located]
+
+ DESCRIPTION:
+
+[Detailed description of problem. Don't just say "<blah>
+doesn't work, here's a fix," explain what your program does
+to get to the <blah> state. If this is a request for an
+enhancement, justify it.]
+
+ REPEAT BY:
+
+[What you did to get the error; include test program or session
+transcript if at all possible. If you include a program, make
+sure it depends only on libraries in the X distribution, not
+on any vendor or third-party libraries. Be specific; if we can't
+reproduce it, we can't fix it. Don't just say "run this program
+and it will be obvious," tell us exactly what we should see when
+the program is run. Bug reports without a clear, deterministic
+way of reproducing them will be fixed only after all bug reports
+that do.]
+
+ SAMPLE FIX:
+
+[Preferred, but not necessary. Please send context diffs (`diff
+-c original-file fixed-file`). Be sure to include our "XConsortium"
+ident line in any diffs. The best way to do this is to add your
+own versioning line immediately after ours.]
+
+[PLEASE make your Subject: line as descriptive as possible.
+Subjects like "xterm bug" or "bug report" are not helpful!]
+[Remove all the explanatory text in brackets before mailing.]
+[Send to xbugs@x.org, as shown in the sample message header above]

+ * This doesn't work the way it does on every other system. On FreeBSD it's

+ * what it says in the ld and ld.so man pages, which are rather vague on the
+ * matter.
+ *
+ * But we do know that if a) you do what the X Project team does and set your
+ * ProjectRoot to something like "/X11", and b) you have other X libraries,
+ * e.g. in /usr/X11R6/lib, and you have added /usr/X11R6/lib to your
+ * ld.so.cache with ldconfig, then any programs linked with this "hint" will
+ * find that ld.so ignores the "hint" at runtime and loads the libraries in
+ * the ld.so.cache, i.e.the wrong ones, instead! Empirically we find that
+ * the run-path is only used as a last resort to find the libraries, after
+ * the LD_LIBRARY_PATH and ld.so.cache.
+ *
+ * N. B. to FreeBSD users who are not familiar with the semantics of the run-
+ * path on other systems. The run-path is akin to a per-program ld.so.cache.
+ * If a program is linked with a run-path, that run-path should take
+ * precedence over _everything_ else! In my opinion ldconfig and the
+ * ld.so.cache should be deprecated immediately now that FreeBSD has run-
+ * paths. Any program that needs libraries that are outside the "well known"
+ * locations should be linked with a run-path.
+ *
+ * All of which begs the question: If this option doesn't work in any useful
+ * way, why did they (FreeBSD) bother to add it? It would be nice if FreeBSD
+ * would fix ld.so so that run-paths are truly useful.
+ *
+ * Using run-paths is added with the intent that vendors who ship X for
+ * FreeBSD should use it too. Once everyone uses it then there will be no
+ * reason for FreeBSD to assume that it knows where X libraries are installed
+ * and they can remove it from the list of directories they add to ld.so.cache
+ * in their /etc/rc file.

+ * and Shell.h files; or Motif's XmStrDefs.c and XmStrDefs.h files.
+ *
+ * The 'files' argument is the list of files that will be produced by
+ * this rule, e.g., for Xt they would be "Shell.h StringDefs.c StringDefs.h"
+ * and for Motif they would be "XmStrDefs.c XmStrDefs.h".
+ *
+ * The 'source' argument is the string-list file to be parsed, e.g., in
+ * Xt that would be "util/string.list". For Motif 2.0 it would be
+ * "../../tools/makestr/xmstring.list", and for Motif-CDE1 it would be
+ * "util/xmstring.list".
+ *
+ * The 'options' argument is passed by the library's Imakefile, see the
+ * Xt Imakefile for an example. Typically this would be nothing, -intelabi,
+ * or -sparcabi; there are other choices, but these are typical.
+ *
+ * The 'depends' argument names additional files the target files
+ * depend on. It should name the #ctmpl and #htmpl files from the
+ * 'source' file.
+ *
+ * The 'dest' argument is the C source output file. For Xt this should
+ * be "StringDefs.c", and for all versions of Motif it would be "XmStrDefs.c"
+ *
+ * Headers are generated and named according to data in the 'source'
+ * file.

+Make Variables
+
+The following make variables are used by imake rules and may be set in
+an individual Imakefile.
+
+DEFINES program-specific -D flags and other arguments
+ to pass to the C compiler, lint, and makedepend.
+DEPEND_DEFINES program-specific flags in addition to
+ $(DEFINES) to pass to lint and makedepend.
+ This is usually used when there are special
+ compilation rules for individual files, and
+ the defines passed to those files affect
+ makedepend results. If they can be passed to
+ all files during the makedepend step without
+ affecting the results for other files,
+ DEPEND_DEFINES is used to do that. Example is
+ the Xlib Imakefile.
+INCLUDES program-specific -I flags.
+HEADERS .h files to install with "make includes" and
+ "make install". If this Imakefile includes
+ Library.tmpl there are no headers, include
+ this line instead of a HEADERS definition:
+ #define LibHeaders NO
+REQUIREDLIBS when building a shared library, other libraries used
+ by this library that should be referenced at
+ link time.
+LINTLIBS program-specific libraries for lint.
+LOCAL_LDFLAGS program-specific flags for the linker.
+LOCAL_LIBRARIES project libraries (usually specified
+ as -lname) needed by this program.
+ For example, "-lXt -lXext -lX11".
+ Used by SimpleProgramTarget and
+ ComplexProgramTarget* rules.
+ Do not include any system-specific libraries here.
+SYS_LIBRARIES system libraries (usually specified
+ as -lname) needed by this program.
+ For example "MathLibrary".
+ Do not include any system-specific libraries
+ such as "-lnsl" here; they are automatically
+ added to the link command by the
+ vendor-specific .cf file.
+SUBDIRS for an Imakefile in a directory containing
+ subdirectories, this names the subdirectories.
+ Such an Imakefile also needs to #define IHaveSubdirs
+ and call MakeSubdirs() and DependSubdirs().
+MANSUFFIX suffix used by InstallManPage* rules.
+ May be set to $(LIBMANSUFFIX) or $(FILEMANSUFFIX) in
+ directories for libraries or data files.
+
+
+Rule-specific variables that may be set in an individual Imakefile.
+If you aren't using these rules, you may need variables with a similar
+function, but you need not use these names. However, following these
+conventions may make your Imakefile easier to read and maintain.
+
+DEPLIBS library dependencies for ComplexProgramTarget
+SRCS source files used by ComplexProgramTarget and
+ DependTarget.
+OBJS object files used by ComplexProgramTarget

+
+Variables that can be set on the make command line:
+
+DESTDIR directory under which "make install" should
+ install instead of "/"; used only for testing
+ "make install" rules.
+FILE file for "lint1" target to run lint on.
+CDEBUGFLAGS -g and/or -O flag to control C compiler optimization.
+CXXDEBUGFLAGS -g and/or -O flag to control C++ optimization.
+LDSTRIPFLAGS flag to have linker strip objects (typically -x).
+ Typically set to the empty string to prevent
+ the linker from stripping objects; use this
+ way when setting CDEBUGFLAGS to "-g".
+
+These variables are set in project-specific files such as X11.tmpl.
+They should NOT be set in an Imakefile. These variables are sometimes
+misused; they are included here to remind Imakefile writers NOT to use
+them:
+
+EXTRA_DEFINES project-specific -D flags
+EXTRA_INCLUDES project-specific -I flags
+EXTRA_ICONFIGFILES Additional project-specific imake config files
+ to add to ICONFIGFILES.
+ This is a list of files that define variables
+ that might affect compilation of some files.
+
+Many other make variables are set up by the imake config files and can
+be used in an Imakefile. The easiest way to discover them is to look
+at the Makefile generated by an empty Imakefile.
+
+
+Comments
+
+Use C comment syntax in an Imakefile for comments that should not
+appear in the resulting Makefile.
+Use "XCOMM" at the start of each
+line to produce a comment that will appear in the Makefile.
+(The "XCOMM" will
+be translated into the Makefile comment character "#" by imake.)
+Do NOT use "#" as a comment character in Imakefiles; it confuses the C
+preprocessor used by imake on some systems.
+
+
+Imake variables
+
+Don't abuse the variables in X11.tmpl that describe
+particular pieces of X by using them to describe your own subsystems.
+Instead, create new variables that are defaulted using
+Imake.tmpl variables.
+
+
+Examples
+
+Since the easiest way to write an Imakefile is to start with one that
+works, here are some short, easy-to-read Imakefile examples in the X
+distribution:
+
+with subdirs: config/Imakefile
+library: lib/Xau/Imakefile
+simple program: programs/xdpyinfo/Imakefile
+complex progs: programs/xclipboard/Imakefile
+complex prog: programs/xmodmap/Imakefile
+
+Common Rules
+
+Here are some of the common rules for building programs. How to use
+them is described in Imake.rules and in the O'Reilly book "Software
+Portability with imake."
+
+Basic program-building rules
+
+All of these except NormalProgramTarget also generate rules to install
+the program and its manual page, and to generate dependencies.
+
+SimpleProgramTarget Use if there is only one program to be made
+ and it has only one source file.
+
+ComplexProgramTarget Use if there is only one program to be made
+ and it has multiple source files. Set SRCS to
+ the names of the source files, set OBJS to
+ the names of the object files, and set DEPLIBS
+ to the libraries that this program depends on.
+
+ComplexProgramTarget_1 Like ComplexProgramTarget, but uses SRCS1,
+ OBJS1, and DEPLIBS1 and can be used with
+ ComplexProgramTarget_2 and ComplexProgramTarget_3
+ to build up to three programs in the same directory.
+ Set PROGRAMS to the programs built by all of
+ these rules. For more than 3 programs, use
+ NormalProgramTarget for each.
+ComplexProgramTarget_2 Use after ComplexProgramTarget_1 for the
+ second program in a directory. Uses SRCS2,
+ OBJS2, and DEPLIBS2.
+ComplexProgramTarget_3 Use after ComplexProgramTarget_2 for the
+ third program in a directory. Uses SRCS3,
+ OBJS3, and DEPLIBS3.
+
+NormalProgramTarget Build a program. Can be used multiple times
+ with different arguments in the same Imakefile.
+
+Lower level rules, often used with NormalProgramTarget
+
+InstallProgram install a program.
+
+InstallManPage install a manual page.
+
+DependTarget() include once at end of Imakefile with
+ NormalProgramTarget rules or that uses Library.tmpl.
+ Generates dependencies for files named in SRCS.
+
+Manual page rules, commonly used only in special documentation directories:
+
+InstallManPage
+InstallManPageLong
+InstallManPageAliases
+
+Other rules:
+
+SpecialCObjectRule Compile a C file with special flags.
+AllTarget Declare additional targets to build.
+InstallAppDefaults Install X application defaults file.
+
+Imakefile for directory with subdirectories
+
+XCOMM this is a sample Imakefile for a directory containing subdirectories
+#define IHaveSubdirs
+#define PassCDebugFlags CDEBUGFLAGS="$(CDEBUGFLAGS)"
+SUBDIRS = list of subdirs ...
+MakeSubdirs($(SUBDIRS))
+DependSubdirs($(SUBDIRS))
+
+
+Common Targets
+
+These targets are typically NOT defined explicitly by the Imakefile
+writer; rather they are generated automatically by imake rules.
+They are listed here for the convenience of people using the resulting
+Makefile, not people writing the original Imakefile.
+
+all Default rule; builds whatever is in this directory.
+Makefile Remake the Makefile (use after changing Imakefile).
+ Run "make depend" after.
+Makefiles Remake all Makefiles in subdirectories. (Does
+ nothing if no subdirectories.)
+ Run "make depend" after.
+includes Generate and install in the tree any necessary
+ header files.
+depend Update dependencies in the Makefile calculated
+ by examining the source files.
+install Install what "make all" built on the system.
+install.man Install manual pages.
+clean Remove built objects and other derived files.
+lint Run lint.
+tags Create a tags file.

+ * These definitions are now extended to work with the X sources and
+ * external sources wishing to build shared libs.
+ *
+ * A library can create it's own shlibs (.so) or can be incorporated into
+ * another "host" lib. All libraries generate stub (.sa) files.
+ * A "host" lib does all the work to generate the stubs for itself and its
+ * "guests", invoking the "guest" Makefiles to create the objects for
+ * inclusion into the "host" shlib. A "guest" lib will ask the "host" to
+ * create the stubfiles, then copy its own into its directory.
+ * Most external libs are "host" libs; the concept of "guest" is a holdover
+ * from older libs during the days of scarce shared library address space.
+ *
+ * To create a simple "host" shared lib, Xfoo, define:
+ *
+ * JUMP_ROOT_Xfoo = <source directory>
+ * JUMP_IS_HOST_Xfoo = YES
+ * JUMP_STUBLIBS_Xfoo = libXfoo.sa
+ * JUMP_DIR_Xfoo = $(JUMP_ROOT_Xfoo)/shared <work directory>
+ * JUMP_DEFS_Xfoo = -DFOO <defs for jump files>
+ * JUMP_VARS_Xfoo = $(JUMP_ROOT_Xfoo)/jump_vars <see DLL docs>
+ * JUMP_FUNCS_Xfoo = $(JUMP_ROOT_Xfoo)/jump_funcs <see DLL docs>
+ * JUMP_IGNORE_Xfoo = $(JUMP_ROOT_Xfoo)/jump_ignore <see DLL docs>
+ * JUMP_EXPORT_Xfoo = $(JUMP_DIR_Xfoo)/jump.vars <exported symbols>
+ * JUMP_IMPORT_Xfoo = $(JUMP_EXPORT_Xbar) <imported symbols>
+ * JUMP_ADDRESS_Xfoo = 0xXXXXXXXX <fill in with address>
+ * JUMP_JUMPTABLESIZE_Xfoo = 0x4000 <adjust if necessary>
+ * JUMP_GOTSIZE_Xfoo = 4096 <adjust if necessary>
+ * JUMP_STUBNAMES_Xfoo = libXfoo <and others>
+ * JUMP_STUBS_IMPORT_Xfoo = /usr/lib/libc.sa <and others>
+ * JUMP_LDLIBS_Xfoo = `$(CC) --print-libgcc-file-name` -lc <and others>
+ *
+ * To create a complex "host", you need to add
+ * JUMP_SIBARS_Xt = jump/libXbar.a~ <and others>
+ * These are the archives of the shared objects of the "guest" libs. They
+ * need to be added to the JUMP_LDLIBS_Xfoo lines.
+ *
+ * For further clarification, study the definitions of libXaw, a simple "host"

+ * === C Compiler Setup ==========================================
+ *
+ * For SunPro C, define HasSunC to YES in site.def.
+ * For CenterLine C, define HasCenterLineC to YES in site.def
+ * For gcc or gcc2, define HasGcc or HasGcc2 to YES in site.def
+ * For other compilers, define HasSunC to NO in site.def, then
+ * provide appropriate values for the various compiler related
+ * configuration varibles used here.
+ *
+ * If you say you have the SunPro C compiler, we assume you have
+ * version 2.0.x of the compiler. If you have version 3.0.x instead,
+ * define CCompilerMajorVersion as 3 in site.def
+ *
+ * If you don't tell us which C compiler you have, we assume you have
+ * the SunPro C compiler under Solaris 2.x, and the bundled /bin/cc
+ * under SunOS 4.1.x
+ *
+ * === C++ Compiler Setup ==========================================
+ *
+ * For SunPro C++, define HasSunCplusplus to YES in site.def
+ * For CenterLine C++, define HasCenterLineCplusplus to YES in site.def
+ * For Gnu g++ 2.6.x, define HasGcc2ForCplusplus to YES in site.def
+ * For other compilers, define HasCplusplus to YES in site.def, and
+ * check to see if you need to provide values for CplusplusOptions
+ * and/or DefaultCplusplusOptions.
+ *
+ * In any case, you may also need to set CplusplusDependIncludes.
+ *
+ * If you say you have the SunPro C++ compiler, we assume you have
+ * version 3.0.x of the compiler. If you have version 4.0.x instead,
+ * define CplusplusCompilerMajorVersion as 4 in site.def.

+ *
+ * imake: the include-make program.
+ *
+ * Usage: imake [-Idir] [-Ddefine] [-T template] [-f imakefile ] [-C Imakefile.c ] [-s] [-e] [-v] [make flags]
+ *
+ * Imake takes a template file (Imake.tmpl) and a prototype (Imakefile)
+ * and runs cpp on them producing a Makefile. It then optionally runs make
+ * on the Makefile.
+ * Options:
+ * -D define. Same as cpp -D argument.
+ * -I Include directory. Same as cpp -I argument.
+ * -T template. Designate a template other
+ * than Imake.tmpl
+ * -f specify the Imakefile file
+ * -C specify the name to use instead of Imakefile.c
+ * -s[F] show. Show the produced makefile on the standard
+ * output. Make is not run is this case. If a file
+ * argument is provided, the output is placed there.
+ * -e[F] execute instead of show; optionally name Makefile F
+ * -v verbose. Show the make command line executed.
+ *
+ * Environment variables:
+ *
+ * IMAKEINCLUDE Include directory to use in addition to "."
+ * IMAKECPP Cpp to use instead of /lib/cpp
+ * IMAKEMAKE make program to use other than what is
+ * found by searching the $PATH variable.
+ * Other features:
+ * imake reads the entire cpp output into memory and then scans it
+ * for occurences of "@@". If it encounters them, it replaces it with
+ * a newline. It also trims any trailing white space on output lines
+ * (because make gets upset at them). This helps when cpp expands
+ * multi-line macros but you want them to appear on multiple lines.
+ * It also changes occurences of "XCOMM" to "#", to avoid problems
+ * with treating commands as invalid preprocessor commands.
+ *
+ * The macros MAKEFILE and MAKE are provided as macros
+ * to make. MAKEFILE is set to imake's makefile (not the constructed,
+ * preprocessed one) and MAKE is set to argv[0], i.e. the name of
+ * the imake program.
+ *
+ * Theory of operation:
+ * 1. Determine the name of the imakefile from the command line (-f)
+ * or from the content of the current directory (Imakefile or imakefile).
+ * Call this <imakefile>. This gets added to the arguments for
+ * make as MAKEFILE=<imakefile>.
+ * 2. Determine the name of the template from the command line (-T)
+ * or the default, Imake.tmpl. Call this <template>
+ * 3. Determine the name of the imakeCfile from the command line (-C)
+ * or the default, Imakefile.c. Call this <imakeCfile>
+ * 4. Store lines of input into <imakeCfile>:
+ * - A c-style comment header (see ImakefileCHeader below), used
+ * to recognize temporary files generated by imake.
+ * - If DEFAULT_OS_NAME is defined, format the utsname struct and
+ * call the result <defaultOsName>. Add:
+ * #define DefaultOSName <defaultOsName>
+ * - If DEFAULT_OS_MAJOR_REV is defined, format the utsname struct
+ * and call the result <defaultOsMajorVersion>. Add:
+ * #define DefaultOSMajorVersion <defaultOsMajorVersion>
+ * - If DEFAULT_OS_MINOR_REV is defined, format the utsname struct
+ * and call the result <defaultOsMinorVersion>. Add:
+ * #define DefaultOSMinorVersion <defaultOsMinorVersion>
+ * - If DEFAULT_OS_TEENY_REV is defined, format the utsname struct
+ * and call the result <defaultOsTeenyVersion>. Add:
+ * #define DefaultOSTeenyVersion <defaultOsTeenyVersion>
+ * - If DEFAULT_MACHINE_ARCITECTURE is defined, format the utsname struct
+ * and define the corresponding macro. (For example on the amiga,
+ * this will define amiga in addition to m68k).
+ * - If the file "localdefines" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_LOCAL_DEFINES "localdefines"
+ * #include IMAKE_LOCAL_DEFINES
+ * - If the file "admindefines" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_ADMIN_DEFINES "admindefines"
+ * #include IMAKE_ADMIN_DEFINES
+ * - The following lines:
+ * #define INCLUDE_IMAKEFILE < <imakefile> >
+ * #define IMAKE_TEMPLATE " <template> "
+ * #include IMAKE_TEMPLATE
+ * - If the file "adminmacros" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_ADMIN_MACROS "adminmacros"
+ * #include IMAKE_ADMIN_MACROS
+ * - If the file "localmacros" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_LOCAL_MACROS "localmacros"
+ * #include IMAKE_LOCAL_MACROS
+ * 5. Start up cpp and provide it with this file.
+ * Note that the define for INCLUDE_IMAKEFILE is intended for
+ * use in the template file. This implies that the imake is
+ * useless unless the template file contains at least the line
+ * #include INCLUDE_IMAKEFILE
+ * 6. Gather the output from cpp, and clean it up, expanding @@ to
+ * newlines, stripping trailing white space, cpp control lines,
+ * and extra blank lines, and changing XCOMM to #. This cleaned
+ * output is placed in a new file, default "Makefile", but can
+ * be specified with -s or -e options.
+ * 7. Optionally start up make on the resulting file.
+ *
+ * The design of the template makefile should therefore be:
+ * <set global macros like CFLAGS, etc.>
+ * <include machine dependent additions>
+ * #include INCLUDE_IMAKEFILE
+ * <add any global targets like 'clean' and long dependencies>

+.TH IMAKE 1 "Release 6.1" "X Version 11"
+.SH NAME
+imake \- C preprocessor interface to the make utility
+.SH SYNOPSIS
+\fBimake\fP [ \fB\-D\fP\fIdefine\fP ] [ \fB\-I\fP\fIdir\fP ]
+[ \fB\-T\fP\fItemplate\fP ]
+[ \fB\-f\fP \fIfilename\fP ] [ \fB\-C\fP \fIfilename\fP ]
+[ \fB\-s\fP \fIfilename\fP ] [ \fB\-e\fP ]
+[ \fB\-v\fP ]
+.SH DESCRIPTION
+.I Imake
+is used to
+generate \fIMakefiles\fP from a template, a set of \fIcpp\fP macro functions,
+and a per-directory input file called an \fIImakefile\fP. This allows machine
+dependencies (such as compiler options, alternate command names, and special
+\fImake\fP rules) to be kept separate from the descriptions of the
+various items to be built.
+.SH OPTIONS
+The following command line options may be passed to \fIimake\fP:
+.TP 8
+.B \-D\fIdefine\fP
+This option is passed directly to \fIcpp\fP. It is typically used to set
+directory-specific variables. For example, the X Window System uses this
+flag to set \fITOPDIR\fP to the name of the directory containing the top
+of the core distribution and \fICURDIR\fP to the name of the current
+directory, relative to the top.
+.TP 8
+.B \-I\fIdirectory\fP
+This option is passed directly to \fIcpp\fP. It is typically used to
+indicate the directory in which the \fIimake\fP template and configuration
+files may be found.
+.TP 8
+.B \-T\fItemplate\fP
+This option specifies the name of the master template file (which is usually
+located in the directory specified with \fI\-I\fP) used by \fIcpp\fP.
+The default is \fIImake.tmpl\fP.
+.TP 8
+.B \-f \fIfilename\fP
+This option specifies the name of the per-directory input file. The default
+is \fIImakefile\fP.
+.TP 8
+.B \-C \fIfilename\fP
+This option specifies the name of the .c file that is constructed in the
+current directory. The default is \fIImakefile.c\fP.
+.TP 8
+.B \-s \fIfilename\fP
+This option specifies the name of the \fImake\fP description file to be
+generated but \fImake\fP should not be invoked.
+If the \fIfilename\fP is a dash (\-), the
+output is written to \fIstdout\fP. The default is to generate, but
+not execute, a \fIMakefile\fP.
+.TP 8
+.B \-e
+This option indicates the \fIimake\fP should execute the generated
+\fIMakefile\fP. The default is to leave this to the user.
+.TP 8
+.B \-v
+This option indicates that \fIimake\fP should print the \fIcpp\fP command line
+that it is using to generate the \fIMakefile\fP.
+.SH "HOW IT WORKS"
+\fIImake\fP invokes \fIcpp\fP with any \fI\-I\fP or \fI\-D\fP flags passed
+on the command line and passes the name of a file containing the
+following 3 lines:
+.sp
+.nf
+ #define IMAKE_TEMPLATE "Imake.tmpl"
+ #define INCLUDE_IMAKEFILE <Imakefile>
+ #include IMAKE_TEMPLATE
+.fi
+.sp
+where \fIImake.tmpl\fP and \fIImakefile\fP may be overridden by the
+\fI\-T\fP and \fI\-f\fP command options, respectively.
+.PP
+The IMAKE_TEMPLATE typically
+reads in a file containing machine-dependent parameters
+(specified as \fIcpp\fP symbols), a site-specific parameters file,
+a file defining variables,
+a file
+containing \fIcpp\fP macro functions for generating \fImake\fP rules, and
+finally the \fIImakefile\fP (specified by INCLUDE_IMAKEFILE) in the current
+directory. The \fIImakefile\fP uses the macro functions to indicate what
+targets should be built; \fIimake\fP takes care of generating the appropriate
+rules.
+.PP
+.I Imake
+configuration files contain two types of variables, imake variables
+and make variables. The imake variables are interpreted by cpp when
+.I imake
+is run. By convention they are mixed case. The make variables are
+written into the
+.I Makefile
+for later interpretation by
+.I make.
+By convention make variables are upper case.
+.PP
+The rules file (usually named \fIImake.rules\fP in the configuration
+directory) contains a variety of \fIcpp\fP macro functions that are
+configured according to the current platform. \fIImake\fP replaces
+any occurrences of the string ``@@'' with a newline to allow macros that
+generate more than one line of \fImake\fP rules.
+For example, the macro
+.ta 1i 1.6i 5i
+.nf
+
+#define program_target(program, objlist) @@\e
+program: objlist @@\e
+ $(CC) \-o $@ objlist $(LDFLAGS)
+
+.fi
+when called with
+.I "program_target(foo, foo1.o foo2.o)"
+will expand to
+.nf
+
+foo: foo1.o foo2.o
+ $(CC) \-o $@ foo1.o foo2.o $(LDFLAGS)
+
+.fi
+.PP
+\fIImake\fP also replaces any occurrences of the word ``XCOMM'' with
+the character ``#'' to permit placing comments in the Makefile without
+causing ``invalid directive'' errors from the preprocessor.
+.PP
+Some complex \fIimake\fP macros require generated \fImake\fP variables
+local to each invocation of the macro, often because their value
+depends on parameters passed to the macro.
+Such variables can be created by using an \fIimake\fP variable
+of the form \fBXVARdef\fP\fIn\fP, where \fIn\fP is a single digit.
+A unique \fImake\fP variable will be substituted. Later occurrences
+of the variable \fBXVARuse\fP\fIn\fP will
+be replaced by the variable created by the corresponding
+\fBXVARdef\fP\fIn\fP.
+.PP
+On systems whose \fIcpp\fP reduces multiple tabs and spaces to a single
+space, \fIimake\fP attempts to put back any necessary tabs (\fImake\fP is
+very picky about the difference between tabs and spaces). For this reason,
+colons (:) in command lines must be preceded by a backslash (\\).
+.SH "USE WITH THE X WINDOW SYSTEM"
+The X Window System uses \fIimake\fP extensively, for both full builds within
+the source tree and external software. As mentioned above, two special
+variables, \fITOPDIR\fP and \fICURDIR,\fP are set to make referencing files
+using relative path names easier. For example, the following command is
+generated automatically to build the \fIMakefile\fP in the directory
+\fIlib/X/\fP (relative to the top of the sources):
+.sp
+.nf
+ % ../.././config/imake \-I../.././config \\
+ \-DTOPDIR=../../. \-DCURDIR=./lib/X
+.fi
+.sp
+When building X programs outside the source tree, a special symbol
+\fIUseInstalled\fP is defined and \fITOPDIR\fP and
+\fICURDIR\fP are omitted. If the configuration files have been
+properly installed, the script \fIxmkmf\fP(1) may be used.
+.SH "INPUT FILES"
+Here is a summary of the files read by
+.I imake
+as used by X.
+The indentation shows what files include what other files.
+.nf
+.sp
+.ta 3i
+ Imake.tmpl generic variables
+ site.def site-specific, BeforeVendorCF defined
+ *.cf machine-specific
+ *Lib.rules shared library rules
+ site.def site-specific, AfterVendorCF defined
+ Imake.rules rules
+ Project.tmpl X-specific variables
+ *Lib.tmpl shared library variables
+ Imakefile
+ Library.tmpl library rules
+ Server.tmpl server rules
+ Threads.tmpl multi-threaded rules
+.fi
+.LP
+Note that \fIsite.def\fP gets included twice, once before the
+\fI*.cf\fP file and once after. Although most site customizations
+should be specified after the \fI*.cf\fP file, some, such as the
+choice of compiler, need to be specified before, because other
+variable settings may depend on them.
+.LP
+The first time \fIsite.def\fP is included, the variable BeforeVendorCF
+is defined, and the second time, the variable AfterVendorCF is
+defined. All code in \fIsite.def\fP should be inside an #ifdef for
+one of these symbols.
+.SH FILES
+.ta 3i
+Imakefile.c temporary input file for cpp
+.br
+/tmp/Imf.XXXXXX temporary Makefile for -s
+.br
+/tmp/IIf.XXXXXX temporary Imakefile if specified Imakefile uses # comments
+.br
+/lib/cpp default C preprocessor
+.DT
+.SH "SEE ALSO"
+make(1), xmkmf(1)
+.br
+S. I. Feldman,
+.I
+Make \(em A Program for Maintaining Computer Programs
+.SH "ENVIRONMENT VARIABLES"
+The following environment variables may be set, however their use is not
+recommended as they introduce dependencies that are not readily apparent
+when \fIimake\fP is run:
+.TP 5
+.B IMAKEINCLUDE
+If defined, this specifies a ``\-I'' include argument to pass to the
+C preprocessor. E.g., ``\-I/usr/X11/config''.
+.TP 5
+.B IMAKECPP
+If defined, this should be a valid path to a preprocessor program.
+E.g., ``/usr/local/cpp''.
+By default,
+.I imake
+will use /lib/cpp.
+.TP 5
+.B IMAKEMAKE
+If defined, this should be a valid path to a make program,
+such as ``/usr/local/make''.
+By default,
+.I imake
+will use whatever
+.I make
+program is found using
+.I execvp(3).
+This variable is only used if the ``\-e'' option is specified.

+\-\^\-
+]
+.I sourcefile
+\&.\|.\|.
+.br
+.SH DESCRIPTION
+The
+.B makedepend
+program reads each
+.I sourcefile
+in sequence and parses it like a C-preprocessor,
+processing all
+.I #include,
+.I #define,
+.I #undef,
+.I #ifdef,
+.I #ifndef,
+.I #endif,
+.I #if,
+.I #elif
+and
+.I #else
+directives so that it can correctly tell which
+.I #include,
+directives would be used in a compilation.
+Any
+.I #include,
+directives can reference files having other
+.I #include
+directives, and parsing will occur in these files as well.
+.PP
+Every file that a
+.I sourcefile
+includes,
+directly or indirectly,
+is what
+.B makedepend
+calls a \fIdependency.\fP
+These dependencies are then written to a
+.I makefile
+in such a way that
+.B make(1)
+will know which object files must be recompiled when a dependency has changed.
+.PP
+By default,
+.B makedepend
+places its output in the file named
+.I makefile
+if it exists, otherwise
+.I Makefile.
+An alternate makefile may be specified with the
+.B \-f
+option.
+It first searches the makefile for
+the line
+.sp
+ # DO NOT DELETE THIS LINE \-\^\- make depend depends on it.
+.sp
+or one provided with the
+.B \-s
+option,
+as a delimiter for the dependency output.
+If it finds it, it will delete everything
+following this to the end of the makefile
+and put the output after this line.
+If it doesn't find it, the program
+will append the string to the end of the makefile
+and place the output following that.
+For each
+.I sourcefile
+appearing on the command line,
+.B makedepend
+puts lines in the makefile of the form
+.sp
+ sourcefile.o:\0dfile .\|.\|.
+.sp
+Where \fIsourcefile.o\fP is the name from the command
+line with its suffix replaced with ``.o'',
+and \fIdfile\fP is a dependency discovered in a
+.I #include
+directive while parsing
+.I sourcefile
+or one of the files it included.
+.SH EXAMPLE
+Normally,
+.B makedepend
+will be used in a makefile target so that typing ``make depend'' will
+bring the dependencies up to date for the makefile.
+For example,
+.nf
+ SRCS\0=\0file1.c\0file2.c\0.\|.\|.
+ CFLAGS\0=\0\-O\0\-DHACK\0\-I\^.\^.\^/foobar\0\-xyz
+ depend:
+ makedepend\0\-\^\-\0$(CFLAGS)\0\-\^\-\0$(SRCS)
+.fi
+.SH OPTIONS
+The program
+will ignore any option that it does not understand so that you may use
+the same arguments that you would for
+.B cc(1).
+.TP 5
+.B \-D\fIname\fP=\fIdef\fP \fRor\fP \-D\fIname\fP
+Define.
+This places a definition for
+.I name
+in
+.B makedepend's
+symbol table.
+Without
+.I =def\|
+the symbol becomes defined as ``1''.
+.TP 5
+.B \-I\fIincludedir\fP
+Include directory.
+This option tells
+.B makedepend
+to prepend
+.I includedir
+to its list of directories to search when it encounters
+a
+.I #include
+directive.
+By default,
+.B makedepend
+only searches the standard include directories (usually /usr/include
+and possibly a compiler-dependent directory).
+.TP 5
+.B \-Y\fIincludedir\fP
+Replace all of the standard include directories with the single specified
+include directory; you can omit the
+.I includedir
+to simply prevent searching the standard include directories.
+.TP 5
+.B \-a
+Append the dependencies to the end of the file instead of replacing them.
+.TP 5
+.B \-f\fImakefile\fP
+Filename.
+This allows you to specify an alternate makefile in which
+.B makedepend
+can place its output.
+Specifying ``\-'' as the file name (i.e., \fB\-f\-\fP) sends the
+output to standard output instead of modifying an existing file.
+.TP 5
+.B \-o\fIobjsuffix\fP
+Object file suffix.
+Some systems may have object files whose suffix is something other
+than ``.o''.
+This option allows you to specify another suffix, such as
+``.b'' with
+.I \-o.b
+or ``:obj''
+with
+.I \-o:obj
+and so forth.
+.TP 5
+.B \-p\fIobjprefix\fP
+Object file prefix.
+The prefix is prepended to the name of the object file. This is
+usually used to designate a different directory for the object file.
+The default is the empty string.
+.TP 5
+.B \-s\fIstring\fP
+Starting string delimiter.
+This option permits you to specify
+a different string for
+.B makedepend
+to look for in the makefile.
+.TP 5
+.B \-w\fIwidth\fP
+Line width.
+Normally,
+.B makedepend
+will ensure that every output line that it writes will be no wider than
+78 characters for the sake of readability.
+This option enables you to change this width.
+.TP 5
+.B \-v
+Verbose operation.
+This option causes
+.B makedepend
+to emit the list of files included by each input file on standard output.
+.TP 5
+.B \-m
+Warn about multiple inclusion.
+This option causes
+.B makedepend
+to produce a warning if any input file includes another file more than
+once. In previous versions of
+.B makedepend
+this was the default behavior; the default has been changed to better
+match the behavior of the C compiler, which does not consider multiple
+inclusion to be an error. This option is provided for backward
+compatibility, and to aid in debugging problems related to multiple
+inclusion.
+.TP 5
+.B "\-\^\- \fIoptions\fP \-\^\-"
+If
+.B makedepend
+encounters a double hyphen (\-\^\-) in the argument list,
+then any unrecognized argument following it
+will be silently ignored; a second double hyphen terminates this
+special treatment.
+In this way,
+.B makedepend
+can be made to safely ignore esoteric compiler arguments that might
+normally be found in a CFLAGS
+.B make
+macro (see the
+.B EXAMPLE
+section above).
+All options that
+.B makedepend
+recognizes and appear between the pair of double hyphens
+are processed normally.
+.SH ALGORITHM
+The approach used in this program enables it to run an order of magnitude
+faster than any other ``dependency generator'' I have ever seen.
+Central to this performance are two assumptions:
+that all files compiled by a single
+makefile will be compiled with roughly the same
+.I \-I
+and
+.I \-D
+options;
+and that most files in a single directory will include largely the
+same files.
+.PP
+Given these assumptions,
+.B makedepend
+expects to be called once for each makefile, with
+all source files that are maintained by the
+makefile appearing on the command line.
+It parses each source and include
+file exactly once, maintaining an internal symbol table
+for each.
+Thus, the first file on the command line will take an amount of time
+proportional to the amount of time that a normal C preprocessor takes.
+But on subsequent files, if it encounters an include file
+that it has already parsed, it does not parse it again.
+.PP
+For example,
+imagine you are compiling two files,
+.I file1.c
+and
+.I file2.c,
+they each include the header file
+.I header.h,
+and the file
+.I header.h
+in turn includes the files
+.I def1.h
+and
+.I def2.h.
+When you run the command
+.sp
+ makedepend\0file1.c\0file2.c
+.sp
+.B makedepend
+will parse
+.I file1.c
+and consequently,
+.I header.h
+and then
+.I def1.h
+and
+.I def2.h.
+It then decides that the dependencies for this file are
+.sp
+ file1.o:\0header.h\0def1.h\0def2.h
+.sp
+But when the program parses
+.I file2.c
+and discovers that it, too, includes
+.I header.h,
+it does not parse the file,
+but simply adds
+.I header.h,
+.I def1.h
+and
+.I def2.h
+to the list of dependencies for
+.I file2.o.
+.SH "SEE ALSO"
+cc(1), make(1)
+.SH BUGS
+.B makedepend
+parses, but does not currently evaluate, the SVR4
+#predicate(token-list) preprocessor expression;
+such expressions are simply assumed to be true.
+This may cause the wrong
+.I #include
+directives to be evaluated.
+.PP
+Imagine you are parsing two files,
+say
+.I file1.c
+and
+.I file2.c,
+each includes the file
+.I def.h.
+The list of files that
+.I def.h
+includes might truly be different when
+.I def.h
+is included by
+.I file1.c
+than when it is included by
+.I file2.c.
+But once
+.B makedepend
+arrives at a list of dependencies for a file,
+it is cast in concrete.

+.TH LNDIR 1 "Release 6.1" "X Version 11"
+.SH NAME
+lndir \- create a shadow directory of symbolic links to another directory tree
+.SH SYNOPSIS
+.B lndir
+[
+.B \-silent
+] [
+.B \-ignorelinks
+]
+.I \|fromdir\|
+[
+.I todir
+]
+.SH DESCRIPTION
+The
+.I lndir
+program makes a shadow copy
+.I todir
+of a directory tree
+.I fromdir,
+except that the shadow is not
+populated with real files but instead with symbolic links pointing at
+the real files in the
+.I fromdir
+directory tree. This is usually useful for maintaining source code for
+different machine architectures. You create a shadow directory
+containing links to the real source, which you will have usually
+mounted from a remote machine. You can build in the shadow tree, and
+the object files will be in the shadow directory, while the
+source files in the shadow directory are just symlinks to the real
+files.
+.PP
+This scheme has the advantage that if you update the source, you need not
+propagate the change to the other architectures by hand, since all
+source in all shadow directories are symlinks to the real thing: just cd
+to the shadow directory and recompile away.
+.PP
+The
+.I todir
+argument is optional and defaults to the current directory. The
+.I fromdir
+argument may be relative (e.g., ../src) and is relative to
+.I todir
+(not the current directory).
+.PP
+.\" CVS.adm is used by the Concurrent Versions System.
+Note that RCS, SCCS, CVS and CVS.adm directories are not shadowed.
+.PP
+If you add files, simply run
+.I lndir
+again. New files will be silently added. Old files will be
+checked that they have the correct link.
+.PP
+Deleting files is a more painful problem; the symlinks will
+just point into never never land.
+.PP
+If a file in \fIfromdir\fP is a symbolic link, \fIlndir\fP will make
+the same link in \fItodir\fP rather than making a link back to the
+(symbolic link) entry in \fIfromdir.\fP The \fB\-ignorelinks\fP flag
+changes this behavior.
+.SH OPTIONS
+.IP \-silent
+Normally \fIlndir\fP outputs the name of each subdirectory as it
+descends into it. The \fB\-silent\fP option suppresses these status
+messages.
+.IP \-ignorelinks
+Causes the program to not treat symbolic links in \fIfromdir\fP
+specially. The link created in \fItodir\fP will point back to the
+corresponding (symbolic link) file in \fIfromdir\fP.
+If the link is to a directory, this is almost certainly the wrong thing.
+.IP
+This option exists mostly to emulate the behavior the C version of
+\fIlndir\fP had in X11R6. Its use is not recommended.
+.SH DIAGNOSTICS
+The program displays the name of each subdirectory it enters, followed
+by a colon. The \fB\-silent\fP option suppresses these messages.
+.PP
+A warning message is displayed if the symbolic link cannot be created.
+The usual problem is that a regular file of the same name already
+exists.
+.PP
+If the link already exists but doesn't point to the correct file, the
+program prints the link name and the location where it does point.
+.SH BUGS
+The
+.I patch
+program gets upset if it cannot change the files. You should never run
+.I patch
+from a shadow directory anyway.
+.PP
+You need to use something like
+.nf
+ find todir \|\-type l \|\-print \||\| xargs rm
+.fi
+to clear out all files before you can relink (if fromdir moved, for instance).
+Something like
+.nf
+ find . \|\\! \|\-type d \|\-print
+.fi
+will find all files that are not directories.

+makestrs \- makes string table C source and header(s)
+.SH SYNOPSIS
+.B makestrs [-f source] [-abioptions ...]
+.SH DESCRIPTION
+The
+.I makestrs
+command creates string table C source files and headers.
+If
+.I -f
+.I source
+is not specified
+.I makestrs
+will read from
+.I stdin.
+The C source file is always written to
+.I stdout.
+.I makestrs
+creates one or more C header files as specified in the source file.
+The following options may be specified:
+.I -sparcabi,
+.I -intelabi,
+.I -functionabi,
+.I -arrayperabi,
+and
+.I -defaultabi.
+.LP
+.I -sparcabi
+is used on SPARC platforms conforming to the SPARC
+Compliance Definition, i.e. SVR4/Solaris.
+.LP
+.I -intelabi
+is used on Intel platforms conforming to the System
+V Application Binary Interface, i.e. SVR4.
+.LP
+.I -earlyR6abi
+may be used in addition to
+.I -intelabi
+for situations
+where the vendor wishes to maintain binary compatiblity between
+X11R6 public-patch 11 (and earlier) and X11R6 public-patch 12 (and later).
+.LP
+.I -functionabi
+generates a functional abi to the string table. This
+mechanism imposes a severe performance penalty and it's recommended
+that you not use it.
+.LP
+.I -arrayperabi
+results in a separate array for each string. This is
+the default behavior if makestrs was compiled with -DARRAYPERSTR
+(it almost never is).
+.LP
+.I -defaultabi
+forces the generation of the "normal" string table even
+if makestrs was compiled with -DARRAYPERSTR. Since makestrs is almost
+never compiled with -DARRAYPERSTR this is the default behavior if
+no abioptions are specified.

+.LP
+In words you may have one or more #file directives. Each #file may have
+one or more #table directives.
+.LP
+The #prefix directive determines the string that makestr will prefix
+to each definition.
+.LP
+The #feature directive determines the string that makestr will use
+for the feature-test macro, e.g. X[TM]STRINGDEFINES.
+.LP
+The #externref directive determines the string that makestr will use
+for the extern clause, typically this will be "extern" but Motif wants
+it to be "externalref"
+.LP
+The #externdef directive determines the string that makestr will use
+for the declaration, typically this will be the null string (note that
+makestrs requires a trailing space in this case, i.e. "#externdef "),
+and Motif will use "externaldef(_xmstrings).
+.LP
+The #ctmpl directive determines the name of the file used as a template
+for the C source file that is generated
+.LP
+Each #file <filename> directive will result in a corresponding header
+file by that name containing the appropriate definitions as specified
+by command line options. A single C source file containing the
+declarations for the definitions in all the headers will be printed
+to stdout.
+.LP
+The #htmpl directive determines the name of the file used as a template
+for the C header file that is generated.
+.LP
+Each #table <tablename> directive will be processed in accordance with
+the ABI. On most platforms all tables will be catenated into a single
+table with the name of the first table for that file. To conform to
+the Intel ABI separate tables will be generated with the names indicated.
+.LP
+The template files specified by the #ctmpl and #htmpl directives
+are processed by copying line for line from the template file to
+the appropriate output file. The line containing the string
+.I <<<STRING_TABLE_GOES_HERE>>>
+is not copied to the output file. The appropriate data is then
+copied to the output file and then the remainder of the template
+file is copied to the output file.
+.SH BUGS
+makestrs is not very forgiving of syntax errors. Sometimes you need
+a trailing space after # directives, other times they will mess you
+up. No warning messages are emitted.

+XCOMM Do the equivalent of the 'makedepend' program, but do it right.
+XCOMM
+XCOMM Usage:
+XCOMM
+XCOMM makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
+XCOMM [-o object-suffix]
+XCOMM
+XCOMM Notes:
+XCOMM
+XCOMM The C compiler used can be overridden with the environment
+XCOMM variable "CC".
+XCOMM
+XCOMM The "-v" switch of the "makedepend" program is not supported.
+XCOMM
+XCOMM
+XCOMM This script should
+XCOMM work on both USG and BSD systems. However, when System V.4 comes out,
+XCOMM USG users will probably have to change "silent" to "-s" instead of
+XCOMM "-" (at least, that is what the documentation implies).

+The mkshadow programs makes a "shadow tree" of a directory tree.
+It logically copies all of the "MASTER" directory into ".".
+However, ordinary files, and RCS/SCCS directories are "copied"
+by creating a sybolic link to the corresponding file in MASTER.
+
+The wildmat.c file is by Rich Salz, and from comp.sources.misc, volume 17.
+The savedir.c file is lightly modified from the version written
+by David MacKenzie for GNU fileutils; the Free Software Foundation
+has graciously agreed to waive their usual copyright so this
+program can be distributed by the X Consortium.
+
+If you have problems compiling savedir.c, try setting the DIRENT make
+variable as suggested in the Makefile.
+
+ * Usage: mkshadow [-X exclude_file] [-x exclude_pattern] ... MASTER
+ * Makes the current directory be a "shadow copy" of MASTER.
+ * Sort of like a recursive copy of MASTER to .
+ * However, symbolic links are used instead of actually
+ * copying (non-directory) files.
+ * Also, directories named RCS or SCCS are shared (with a symbolic link).
+ * Warning messages are printed for files (and directories) in .
+ * that don't match a corresponding file in MASTER (though
+ * symbolic links are silently removed).
+ * Also, a warning message is printed for non-directory files
+ * under . that are not symbolic links.
+ *
+ * Files and directories can be excluded from the sharing
+ * with the -X and -x flags. The flag `-x pattern' (or `-xpattern')
+ * means that mkshadow should ignore any file whose name matches
+ * the pattern. The pattern is a "globbing" pattern, i.e. the
+ * characters *?[^-] are interpreted as by the shell.
+ * If the pattern contains a '/' is is matched against the complete
+ * current path (relative to '.'); otherwise, it is matched
+ * against the last component of the path.
+ * A `-X filename' flag means to read a set of exclusion patterns
+ * from the named file, one pattern to a line.

+ * However, symbolic links are used instead of actually
+ * copying (non-directory) files.
+ * Also, directories named RCS or SCCS are shared (with a symbolic link).
+ * Warning messages are printed for files (and directories) in .
+ * that don't match a corresponding file in MASTER (though
+ * symbolic links are silently removed).
+ * Also, a warning message is printed for non-directory files
+ * under SHADOW that are not symbolic links.
+ *
+ * Files and directories can be excluded from the sharing
+ * with the -X and -x flags. The flag `-x pattern' (or `-xpattern')
+ * means that mkshadow should ignore any file whose name matches
+ * the pattern. The pattern is a "globbing" pattern, i.e. the
+ * characters *?[^-] are interpreted as by the shell.
+ * If the pattern contains a '/' is is matched against the complete
+ * current path (relative to '.'); otherwise, it is matched
+ * against the last component of the path.
+ * A `-X filename' flag means to read a set of exclusion patterns
+ * from the named file, one pattern to a line.
+ *

+** April, 1991: Replaced mutually-recursive calls with in-line code
+** for the star character.
+**
+** Special thanks to Lars Mathiesen <thorinn@diku.dk> for the ABORT code.
+** This can greatly speed up failing wildcard patterns. For example:
+** pattern: -*-*-*-*-*-*-12-*-*-*-m-*-*-*
+** text 1: -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1
+** text 2: -adobe-courier-bold-o-normal--12-120-75-75-X-70-iso8859-1
+** Text 1 matches with 51 calls, while text 2 fails with 54 calls. Without
+** the ABORT, then it takes 22310 calls to fail. Ugh. The following
+** explanation is from Lars:
+** The precondition that must be fulfilled is that DoMatch will consume
+** at least one character in text. This is true if *p is neither '*' nor
+** '\0'.) The last return has ABORT instead of FALSE to avoid quadratic
+** behaviour in cases like pattern "*a*b*c*d" with text "abcxxxxx". With
+** FALSE, each star-loop has to run to the end of the text; with ABORT
+** only the last one does.
+**
+** Once the control of one instance of DoMatch enters the star-loop, that
+** instance will return either TRUE or ABORT, and any calling instance
+** will therefore return immediately after (without calling recursively
+** again). In effect, only one star-loop is ever active. It would be
+** possible to modify the code to maintain this context explicitly,
+** eliminating all recursive calls at the cost of some complication and
+** loss of clarity (and the ABORT stuff seems to be unclear enough by
+** itself). I think it would be unwise to try to get this into a
+** released version unless you have a good test data base to try it out

+.SH NAME
+xmkmf \- create a Makefile from an Imakefile
+.SH SYNOPSIS
+.B xmkmf
+[ -a ] [
+.I topdir
+[
+.I curdir
+] ]
+.SH DESCRIPTION
+The
+.I xmkmf
+command is the normal way to create a
+.I Makefile
+from an
+.I Imakefile
+shipped with third-party software.
+.PP
+When invoked with no arguments in a directory containing an
+.I Imakefile,
+the
+.I imake
+program is run with arguments appropriate for your system
+(configured into
+.I xmkmf
+when X was built) and generates a
+.I Makefile.
+.PP
+When invoked with the
+.I \-a
+option,
+.I xmkmf
+builds the
+.I Makefile
+in the current directory, and then automatically executes
+``make Makefiles'' (in case there are subdirectories),
+``make includes'',
+and ``make depend'' for you.
+This is the normal way to configure software that is outside
+the X Consortium build tree.
+.PP
+If working inside the X Consortium build tree (unlikely unless you
+are an X developer, and even then this option is never really used), the
+.I topdir
+argument should be specified as the relative pathname from the
+current directory to the top of the build tree. Optionally,
+.I curdir
+may be specified as a relative pathname from the top of the build
+tree to the current directory. It is necessary to supply
+.I curdir
+if the current directory has subdirectories, or the
+.I Makefile
+will not be able to build the subdirectories.
+If a
+.I topdir
+is given,
+.I xmkmf
+assumes nothing is installed on your system and looks for files in
+the build tree instead of using the installed versions.

+ * The purpose of this header is to define the macros ALLOCATE_LOCAL and
+ * DEALLOCATE_LOCAL appropriately for the platform being compiled on.
+ * These macros are used to make fast, function-local memory allocations.
+ * Their characteristics are as follows:
+ *
+ * void *ALLOCATE_LOCAL(int size)
+ * Returns a pointer to size bytes of memory, or NULL if the allocation
+ * failed. The memory must be freed with DEALLOCATE_LOCAL before the
+ * function that made the allocation returns. You should not ask for
+ * large blocks of memory with this function, since on many platforms
+ * the memory comes from the stack, which may have limited size.
+ *
+ * void DEALLOCATE_LOCAL(void *)
+ * Frees the memory allocated by ALLOCATE_LOCAL. Omission of this
+ * step may be harmless on some platforms, but will result in
+ * memory leaks or worse on others.
+ *
+ * Before including this file, you should define two macros,
+ * ALLOCATE_LOCAL_FALLBACK and DEALLOCATE_LOCAL_FALLBACK, that have the
+ * same characteristics as ALLOCATE_LOCAL and DEALLOCATE_LOCAL. The
+ * header uses the fallbacks if it doesn't know a "better" way to define
+ * ALLOCATE_LOCAL and DEALLOCATE_LOCAL. Typical usage would be:
+ *
+ * #define ALLOCATE_LOCAL_FALLBACK(_size) malloc(_size)
+ * #define DEALLOCATE_LOCAL_FALLBACK(_ptr) free(_ptr)

+
+ A Sample Authorization Protocol for X
+
+
+Overview
+
+The following note describes a very simple mechanism for providing individual
+access to an X Window System display. It uses existing core protocol and
+library hooks for specifying authorization data in the connection setup block
+to restrict use of the display to only those clients that show that they
+know a server-specific key called a "magic cookie". This mechanism is *not*
+being proposed as an addition to the Xlib standard; among other reasons, a
+protocol extension is needed to support more flexible mechanisms. We have
+implemented this mechanism already; if you have comments, please send them
+to us.
+
+This scheme involves changes to the following parts of the sample release:
+
+ o xdm
+ - generate random magic cookie and store in protected file
+ - pass name of magic cookie file to server
+ - when user logs in, add magic cookie to user's auth file
+ - when user logs out, generate a new cookie for server
+
+ o server
+ - a new command line option to specify cookie file
+ - check client authorization data against magic cookie
+ - read in cookie whenever the server resets
+ - do not add local machine to host list if magic cookie given
+
+ o Xlib
+ - read in authorization data from file
+ - find data for appropriate server
+ - send authorization data if found
+
+ o xauth [new program to manage user auth file]
+ - add entries to user's auth file
+ - remove entries from user's auth file
+
+This mechanism assumes that the superuser and the transport layer between
+the client and the server is secure. Organizations that desire stricter
+security are encouraged to look at systems such as Kerberos (at Project
+Athena).
+
+
+Description
+
+The sample implementation will use the xdm Display Manager to set up and
+control the server's authorization file. Sites that do not run xdm will
+need to build their own mechanisms.
+
+Xdm uses a random key (seeded by the system time and check sum of /dev/kmem)
+to generate a unique sequence of characters at 16 bytes long. This sequence
+will be written to a file which is made readable only by the server. The
+server will then be started with a command line option instructing it to use
+the contents of the file as the magic cookie for connections that include
+authorization data. This will also disable the server from adding the local
+machine's address to the initial host list. Note that the actual cookie must
+not be stored on the command line or in an environment variable, to prevent
+it from being publicly obtainable by the "ps" command.
+
+If a client presents an authorization name of "MIT-MAGIC-COOKIE-1" and
+authorization data that matches the magic cookie, that client is allowed
+access. If the name or data does not match and the host list is empty,
+that client will be denied access. Otherwise, the existing host-based access
+control will be used. Since any client that is making a connection from a
+machine on the host list will be granted access even if their authorization
+data is incorrect, sites are strongly urged not to set up any default hosts
+using the /etc/X*.hosts files. Granting access to other machines should be
+done by the user's session manager instead.
+
+Assuming the server is configured with an empty host list, the existence of the
+cookie is sufficient to ensure there will be no unauthorized access to the
+display. However, xdm will (continue to) work to minimize the chances of
+spoofing on servers that do not support this authorization mechanism. This
+will be done by grabbing the server and the keyboard after opening the display.
+This action will be surrounded by a timer which will kill the server if the
+grabs cannot be done within several seconds. [This level of security is now
+implemented in patches already sent out.]
+
+After the user logs in, xdm will add authorization entries for each of the
+server machine's network addresses to the user's authorization file (the format
+of which is described below). This file will usually be named .Xauthority in
+the users's home directory; will be owned by the user (as specified by the
+pw_uid and pw_gid fields in the user's password entry), and will be accessible
+only to the user (no group access). This file will contain authorization data
+for all of the displays opened by the user.
+
+When the session terminates, xdm will generate and store a new magic cookie
+for the server. Then, xdm will shutdown its own connection and send a
+SIGHUP to the server process, which should cause the server to reset. The
+server will then read in the new magic cookie.
+
+To support accesses (both read and write) from multiple machines (for use in
+environments that use distributed file systems), file locking is done using
+hard links. This is done by creat'ing (sic) a lock file and then linking it
+to another name in the same directory. If the link-target already exists,
+the link will fail, indicating failure to obtain the lock. Linking is used
+instead of just creating the file read-only since link will fail even for
+the superuser.
+
+Problems and Solutions
+
+There are a few problems with .Xauthority as described. If no home directory
+exists, or if xdm cannot create a file there (disk full), xdm stores the
+cookie in a file in a resource-specified back-up directory, and sets an
+environment variable in the user's session (called XAUTHORITY) naming this
+file. There is also the problem that the locking attempts will need to be
+timed out, due to a leftover lock. Xdm, again, creates a file and set an
+environment variable. Finally, the back-up directory might be full. Xdm,
+as a last resort, provides a function key binding that allows a user to log
+in without having the authorization data stored, and with host-based access
+control disabled.
+
+Xlib
+
+XOpenDisplay in Xlib was enhanced to allow specification of authorization
+information. As implied above, Xlib looks for the data in the
+.Xauthority file of the home directory, or in the file pointed at by the
+XAUTHORITY environment variable instead if that is defined. This required
+no programmatic interface change to Xlib. In addition, a new Xlib routine
+is provided to explicitly specify authorization.
+
+ XSetAuthorization(name, namelen, data, datalen)
+ int namelen, datalen;
+ char *name, *data;
+
+There are three types of input:
+
+ name NULL, data don't care - use default authorization mechanism.
+ name non-NULL, data NULL - use the named authorization; get
+ data from that mechanism's default.
+ name non-NULL, data non-NULL - use the given authorization and data.
+
+This interface is used by xdm and might also be used by any other
+applications that wish to explicitly set the authorization information.
+
+Authorization File
+
+The .Xauthority file is a binary file consisting of a sequence of entries
+in the following format:
+
+ 2 bytes Family value (second byte is as in protocol HOST)
+ 2 bytes address length (always MSB first)
+ A bytes host address (as in protocol HOST)
+ 2 bytes display "number" length (always MSB first)
+ S bytes display "number" string
+ 2 bytes name length (always MSB first)
+ N bytes authorization name string
+ 2 bytes data length (always MSB first)
+ D bytes authorization data string
+
+The format is binary for easy processing, since authorization information
+usually consists of arbitrary data. Host addresses are used instead of
+names to eliminate potentially time-consuming name resolutions in
+XOpenDisplay. Programs, such as xdm, that initialize the user's
+authorization file will have to do the same work as the server in finding
+addresses for all network interfaces. If more than one entry matches the
+desired address, the entry that is chosen is implementation-dependent. In
+our implementation, it is always the first in the file.
+
+The Family is specified in two bytes to allow out-of-band values
+(i.e. values not in the Protocol) to be used. In particular,
+two new values "FamilyLocal" and "FamilyWild" are defined. FamilyLocal
+refers to any connections using a non-network method of connetion from the
+local machine (Unix domain sockets, shared memory, loopback serial line).
+In this case the host address is specified by the data returned from
+gethostname() and better be unique in a collection of machines
+which share NFS directories. FamilyWild is currently used only
+by xdm to communicate authorization data to the server. It matches
+any family/host address pair.
+
+For FamilyInternet, the host address is the 4 byte internet address, for
+FamilyDecnet, the host address is the byte decnet address, for FamilyChaos
+the address is also two bytes.
+
+The Display Number is the ascii representation of the display number
+portion of the display name. It is in ascii to allow future expansion
+to PseudoRoots or anything else that might happen.
+
+A utility called "xauth" will be provided for editing and viewing the
+contents of authorization files. Note that the user's authorization file is
+not the same as the server's magic cookie file.

+:h1.ARITH Module - Portable Module for Multiple Precision Fixed Point Arithmetic
+
+This module provides division and multiplication of 64-bit fixed point
+numbers. (To be more precise, the module works on numbers that take
+two 'longs' to store. That is almost always equivalent to saying 64-bit
+numbers.)
+
+Note: it is frequently easy and desirable to recode these functions in
+assembly language for the particular processor being used, because
+assembly language, unlike C, will have 64-bit multiply products and
+64-bit dividends. This module is offered as a portable version.

+(no intervening move segments) when the interior of the path was
+calculated. Here we use the term "edge" to mean every edge list
+that was created in between changes of direction.
+
+The subpath chains are singly-linked circular chains. For the convenience
+of building them, they direction of the list (from edge to edge) is the
+reverse of the order in which they were built. Within any single edge,
+the subpath chain goes from top-to-bottom. (There might be a violation
+of this because of the way the user started the first chain; see

+:h3.The "pointer" Macro - Define a Generic Pointer
+
+Sadly, many compilers will give a warning message when a pointer to
+one structure is assigned to a pointer to another. We've even seen
+some that give severe errors (when the wrong pointer type is used as
+an initializer or returned from a function). TYPE1IMAGER has routines
+like Dup and Allocate that are perfectly willing to duplicate or
+allocate any of a number of different types of structures. How to
+declare them in a truely portable way?
+
+Well, there is no single good answer that I've found. You can always
+beg the question and "cast" everything. I find this distracting and the
+resulting code ugly. On the other hand, we have found at least one
+compiler that will accept "void *" as a generic pointer that can
+assigned to any other pointer type without error or warning (apparently
+this is also the ANSI standard). So, we define "void *" to be a generic
+pointer. (You might have to change this for your compiler; the "ifndef"
+allows the change to be made on the command line if you want.)

+
+Copying arbitrary bytes in C is a bit of a problem. "strcpy" can't be

+zero bytes. Sadly, there is no standard on the name of such a routine,
+which makes it impossible to write truely portable code to use it.
+
+It turns out that TYPE1IMAGER, when it wants to copy data, frequently
+knows that both the source and destination are aligned on "long"
+boundaries. This allows us to copy by using "long *" pointers. This
+is usually very efficient on almost all processors. Frequently, it
+is more efficient than using general-purpose assembly language routines.
+So, we define a macro to do this in a portable way. "dest" and "source"

+(It might be better to reset the "absolute" coordinates every time a

+the "big error" where our fixed point arithmetic "wraps". However, I
+think I'll keep it this way until something happens to convince me
+otherwise.)

+:eol.
+In general the REGIONS is not smart enough to answer those questions
+itself. (For example, determining if and when a curve changes direction
+may need detailed curve knowledge.) Yet, this must be done efficiently.
+We provide a macro "GOING_TO" where the invoker tells us where it is

+region under construction, and the macro answers the questions above.

+:h3 id=edgelist.The "edgelist" Structure
+
+Regions are represented by a linked list of 'edgelist' structures.
+When a region is complete, the structures are paired, one for the
+left and one for the right edge. While a region is being built,
+this rule may be violated temporarily.
+
+An 'edgelist' structure contains the X values for a given span
+of Y values. The (X,Y) pairs define an edge. We use the crack
+and edge coordinate system, so that integer values of X and Y
+go between pels. The edge is defined between the minimum Y and
+maximum Y.
+
+The linked list is kept sorted from top to bottom, that is, in
+increasing y. Also, if 'e1' is an edgelist structure and 'e2' is the
+next one in the list, they must have exactly the same ymin,ymax values
+or be totally disjoint. These two requirements mean that if e2's ymin
+is less than e1's ymax, it must be exactly equal to e1's ymin. A
+sublist of structures with identical ymin and ymax values is called a
+'swath'.
+
+In addition, edgelist structures are separately linked together based
+on what subpath originally created them; each subpath is kept as a
+separate circular linked list. This information is ignored unless
+continuity checking is invoked. See :hdref refid=subpath. for a
+complete description of this.
+*/

+
+/*SHARED LINE(S) ORIGINATED HERE*/

+/*
+The "edgelist" structure follows the convention of TYPE1IMAGER user
+objects, having a type field and a flag field as the first two
+elements. However, the user never sees "edgelist" structures
+directly; he is given handles to "region" structures only.
+
+By having a type field, we can use the "copy" feature of Allocate()
+to duplicate edge lists quickly.
+
+We also define two flag bits for this structure. The ISDOWN bit is set
+if the edge is going in the direction of increasing Y. The ISAMBIGUOUS
+bit is set if the edge is identical to its neighbor (edge->link); such
+edges may be "left" when they should be "right", or vice versa,
+unnecessarily confusing the continuity checking logic. The FixSubPaths()
+routine in HINTS will swap ambiguous edges if that avoids crossing edges;

+
+:h3.The "freeblock" Structure
+
+The list of available memory blocks is a doubly-linked list. Each
+block begins with the following structure:
+*/
+
+struct freeblock {
+ long size; /* number of 'longs' in block,
+ including this header */
+ struct freeblock *fore; /* forward in doubly-linked list */
+ struct freeblock *back; /* backward in doubly-linked list */
+} ;
+/*
+In addition, each free block has a TRAILER that is simply the 'size'
+repeated. Thus 'size' is found at the beginning of the block and at the
+end of the block (size-1 longs away). 'size' includes both the header
+and the trailer.
+
+When a block is allocated, its 'size' is turned negative (both at the
+beginning and at the end). Thus, checking whether two blocks may be
+combined is very simple. We merely examine both neighboring blocks'
+size to see if they are positive (and hence available for combination).
+
+The memory address returned to the user is therefore one "long" below the
+size, and one extra "long" is added to the end of the block (beyond what
+the user requested) to store the trailing size.
+
+:h3."firstfree" and "lastfree", the Anchors to the Free List

+XCOMM just a hack because of the Sun version of make and nfs.
+XCOMM
+.c.o:
+
+/* Build rule blocks, add one for each server
+ *
+ * If a server needs mfb, its build block should have a line like:
+ * MFBDIR = mfb
+ * Similarly, its build block should have:
+ * CFB4DIR = cfb4 (if the server needs 4 bit cfb)
+ * CFB8DIR = cfb (8 bit cfb)
+ * CFB16DIR = cfb16 (16 bit cfb)
+ * CFB24DIR = cfb24 (24 bit cfb)
+ * CFB32DIR = cfb32 (32 bit cfb)
+ *
+ * If a server does not need all of the above components, simply
+ * omit the relevant lines from the build block.
+ *
+ * Additional ddx directories can be split across three variables:
+ * DDXDIR1, DDXDIR2, and DDXDIR3. Most servers only use DDXDIR1,
+ * but if two servers can be built on a platform then DDXDIR1 is
+ * typically set to the ddx directories that are shared by both
+ * servers, DDXDIR2 is the directories unique to one of the servers,
+ * and DDXDIR3 is the directories unique to the other server.
+ *
+ * If these guidelines are followed, a make at the top of the server
+ * tree should result in each subdirectory being built only once,
+ * even if multiple servers that share subdirectories are being built.

+Support for doublebuffer hardare
+
+This code is designed to support doublebuffer hardware where the
+displayed buffer is selected on a per-pixel basis by an additional bit
+plane, called the select plane. It could probably be easily modified
+to work with systems that use window-id planes.
+
+This is done by creating a new drawable type, DRAWABLE_BUFFER. The
+type has the same exact layout as a window drawable. Your code should
+treat a DRAWABLE_BUFFER the same as it would tread a DRAWABLE_WINDOW
+when handling the gc drawing functions. In addition, PaintWindowBackground,
+CopyWindow, and all of the gc drawing functions to be able to draw into both
+framebuffers. Which framebuffer to draw into is selected by the contents of
+ pWin->devPrivates[frameWindowPrivateIndex].
+The content of the devPrivate is either from frameBuffer[0] or
+frameBuffer[1], depending on which buffer is being drawn into. When
+ pWin->devPrivates[frameWindowPrivateIndex] == frameBuffer[0],
+the functions should draw into the front framebuffer. When
+ pWin->devPrivates[frameWindowPrivateIndex] == frameBuffer[1],
+the functions should draw into the back framebuffer.
+
+In addition, you need to provide a function that allows you to copy
+bits between the buffers (optional since CopyArea can be used) and a
+function that draws into the select plane. Then, you need to register
+your functions and other information, by calling:
+
+void
+RegisterDoubleBufferHardware(pScreen, nInfo, pInfo, frameBuffer, selectPlane,
+ CopyBufferBitsFunc, DrawSelectPlaneFunc)
+ int nInfo;
+ xMbufBufferInfo *pInfo;
+ DevUnion *frameBuffer;
+ DevUnion selectPlane;
+
+"pInfo" is an array indicating which visuals and depths that double
+buffering is supported on. "nInfo" is the length of the array.
+
+"frameBuffer" is array of length 2. The contents of the array element
+is ddx-specific. The content of frameBuffer[0] should, when placed in
+the window private, indicate that framebuffer 0 should be drawn into.
+The contents of frameBuffer[1], when placed into the window private,
+should indicate that framebuffer 1 should be drawn into.
+
+"selectPlane" is ddx-specific. It should contain information
+neccessary for your displayProc to access the select plane.
+It is passed to DrawSelectPlaneFunc.
+
+"CopyBufferBitsFunc" is a ddx-specific function that copies from one
+buffer of a multibuffered window to another buffer. If the CopyBufferBitsFunc
+is NULL, a default function will be used that calls pScreen->CopyArea.
+
+ void CopyBufferBitsFunc(pMBWindow, srcBufferNum, dstBufferNum)
+ mbufWindowPtr pMBWindow;
+ int srcBufferNum, dstBufferNum;
+
+"DrawSelectPlaneFunc" is a ddx-specific function that fills the
+regions "prgn" of select plane with the value "bufferNum". If
+selectPlane is a DrawablePtr (such as a PixmapPtr), you can pass
+NULL for DrawSelectPlaneFunc, a default function will be used that
+calls FillRectangle on the selectPlane.
+
+ void DrawSelectPlaneFunc(pScreen, selectPlane, prgn, bufferNum)
+ ScreenPtr pScreen;
+ DevUnion selectPlane;
+ RegionPtr prgn;
+ long bufferNum;

+.SH NAME
+Xserver \- X Window System display server
+.SH SYNOPSIS
+.B X
+[option ...]
+.SH DESCRIPTION
+.I X
+is the generic name for the X Window System display server. It is
+frequently a link or a copy of the appropriate server binary for
+driving the most frequently used server on a given machine.
+.SH "STARTING THE SERVER"
+The X server is usually started from the X Display Manager program \fIxdm(1)\fP.
+This utility is run from the system boot files and takes care of keeping
+the server running, prompting for usernames and passwords, and starting up
+the user sessions.
+.PP
+Installations that run more than one window system may need to use the
+\fIxinit(1)\fP utility instead of \fIxdm\fP. However, \fIxinit\fP is
+to be considered a tool for building startup scripts and is not
+intended for use by end users. Site administrators are \fBstrongly\fP
+urged to use \fIxdm\fP, or build other interfaces for novice users.
+.PP
+The X server may also be started directly by the user, though this
+method is usually reserved for testing and is not recommended for
+normal operation. On some platforms, the user must have special
+permission to start the X server, often because access to certain
+devices (e.g. /dev/mouse) is restricted.
+.PP
+When the X server starts up, it typically takes over the display. If
+you are running on a workstation whose console is the display, you may
+not be able to log into the console while the server is running.
+.SH OPTIONS
+All of the X servers accept the following command line options:
+.TP 8
+.B :\fIdisplaynumber\fP
+the X server runs as the given \fIdisplaynumber\fP, which by default is 0.
+If multiple X servers are to run simultaneously on a host, each must have
+a unique display number. See the DISPLAY
+NAMES section of the \fIX(1)\fP manual page to learn how to specify
+which display number clients should try to use.
+.TP 8
+.B \-a \fInumber\fP
+sets pointer acceleration (i.e. the ratio of how much is reported to how much
+the user actually moved the pointer).
+.TP 8
+.B \-ac
+disables host-based access control mechanisms. Enables access by any host,
+and permits any host to modify the access control list.
+Use with extreme caution.
+This option exists primarily for running test suites remotely.
+.TP 8
+.B \-audit \fIlevel\fP
+Sets the audit trail level. The default level is 1, meaning only connection
+rejections are reported. Level 2 additionally reports all successful
+connections and disconnects. Level 4 enables messages from the
+SECURITY extension, if present, including generation and revocation of
+authorizations and violations of the security policy.
+Level 0 turns off the audit trail.
+Audit lines are sent as standard error output.
+.TP 8
+.B \-auth \fIauthorization-file\fP
+Specifies a file which contains a collection of authorization records used
+to authenticate access. See also the \fIxdm\fP and \fIXsecurity\fP manual
+pages.
+.TP 8
+.B bc
+disables certain kinds of error checking, for bug compatibility with
+previous releases (e.g., to work around bugs in R2 and R3 xterms and toolkits).
+Deprecated.
+.TP 8
+.B \-bs
+disables backing store support on all screens.
+.TP 8
+.B \-c
+turns off key-click.
+.TP 8
+.B c \fIvolume\fP
+sets key-click volume (allowable range: 0-100).
+.TP 8
+.B \-cc \fIclass\fP
+sets the visual class for the root window of color screens.
+The class numbers are as specified in the X protocol.
+Not obeyed by all servers.
+.TP 8
+.B \-co \fIfilename\fP
+sets name of RGB color database. The default is <XRoot>/lib/X11/rgb,
+where <XRoot> refers to the root of the X11 install tree.
+.ig
+.TP 8
+.B \-config \fIfilename\fP
+reads more options from the given file. Options in the file may be separated
+by newlines if desired. If a '#' character appears on a line, all characters
+between it and the next newline are ignored, providing a simple commenting
+facility. The \fB\-config\fP option itself may appear in the file.
+..
+.TP 8
+.B \-core
+causes the server to generate a core dump on fatal errors.
+.TP 8
+.B \-dpi \fIresolution\fP
+sets the resolution of the screen, in dots per inch.
+To be used when the server cannot determine the screen size from the hardware.
+.TP 8
+.B dpms
+Enable DPMS (when supported).
+.TP 8
+.B \-dpms
+Disable DPMS.
+.TP 8
+.B \-deferglyphs \fIwhichfonts\fP
+specifies the types of fonts for which the server should attempt to use
+deferred glyph loading. \fIwhichfonts\fP can be all (all fonts),
+none (no fonts), or 16 (16 bit fonts only).
+.TP 8
+.B \-f \fIvolume\fP
+sets feep (bell) volume (allowable range: 0-100).
+.TP 8
+.B \-fc \fIcursorFont\fP
+sets default cursor font.
+.TP 8
+.B \-fn \fIfont\fP
+sets the default font.
+.TP 8
+.B \-fp \fIfontPath\fP
+sets the search path for fonts. This path is a comma separated list
+of directories which the X server searches for font databases.
+.TP 8
+.B \-help
+prints a usage message.
+.TP 8
+.B \-I
+causes all remaining command line arguments to be ignored.
+.TP 8
+.B \-kb
+disables the XKEYBOARD extension if present.
+.TP 8
+.B \-nolisten \fItrans-type\fP
+Disable a transport type. For example, TCP/IP connections can be disabled
+with
+.B \-nolisten tcp
+.TP 8
+.B \-nolock
+Disable the use of an X server lock file.
+.TP 8
+.B \-p \fIminutes\fP
+sets screen-saver pattern cycle time in minutes.
+.TP 8
+.B \-pn
+permits the server to continue running if it fails to establish all of
+its well-known sockets (connection points for clients), but
+establishes at least one.
+.TP 8
+.B \-r
+turns off auto-repeat.
+.TP 8
+.B r
+turns on auto-repeat.
+.TP 8
+.B \-s \fIminutes\fP
+sets screen-saver timeout time in minutes.
+.TP 8
+.B \-su
+disables save under support on all screens.
+.TP 8
+.B \-t \fInumber\fP
+sets pointer acceleration threshold in pixels (i.e. after how many pixels
+pointer acceleration should take effect).
+.TP 8
+.B \-terminate
+causes the server to terminate at server reset, instead of continuing to run.
+.TP 8
+.B \-to \fIseconds\fP
+sets default connection timeout in seconds.
+.TP 8
+.B \-tst
+disables all testing extensions (e.g., XTEST, XTrap, XTestExtension1, RECORD).
+.TP 8
+.B tty\fIxx\fP
+ignored, for servers started the ancient way (from init).
+.TP 8
+.B v
+sets video-off screen-saver preference.
+.TP 8
+.B \-v
+sets video-on screen-saver preference.
+.TP 8
+.B \-wm
+forces the default backing-store of all windows to be WhenMapped. This
+is a backdoor way of getting backing-store to apply to all windows.
+Although all mapped windows will have backing store, the backing store
+attribute value reported by the server for a window will be the last
+value established by a client. If it has never been set by a client,
+the server will report the default value, NotUseful. This behavior is
+required by the X protocol, which allows the server to exceed the
+client's backing store expectations but does not provide a way to tell
+the client that it is doing so.
+.TP 8
+.B \-x \fIextension\fP
+loads the specified extension at init.
+This is a no-op for most implementations.
+.SH SERVER DEPENDENT OPTIONS
+Some X servers accept the following options:
+.TP 8
+.B \-ld \fIkilobytes\fP
+sets the data space limit of the server to the specified number of kilobytes.
+A value of zero makes the data size as large as possible. The default value
+of \-1 leaves the data space limit unchanged.
+.TP 8
+.B \-lf \fIfiles\fP
+sets the number-of-open-files limit of the server to the specified number.
+A value of zero makes the limit as large as possible. The default value
+of \-1 leaves the limit unchanged.
+.TP 8
+.B \-ls \fIkilobytes\fP
+sets the stack space limit of the server to the specified number of kilobytes.
+A value of zero makes the stack size as large as possible. The default value
+of \-1 leaves the stack space limit unchanged.
+.TP 8
+.B \-logo
+turns on the X Window System logo display in the screen-saver.
+There is currently no way to change this from a client.
+.TP 8
+.B nologo
+turns off the X Window System logo display in the screen-saver.
+There is currently no way to change this from a client.
+.SH XDMCP OPTIONS
+X servers that support XDMCP have the following options.
+See the \fIX Display Manager Control Protocol\fP specification for more
+information.
+.TP 8
+.B \-query \fIhost-name\fP
+Enable XDMCP and send Query packets to the specified host.
+.TP 8
+.B \-broadcast
+Enable XDMCP and broadcast BroadcastQuery packets to the network. The
+first responding display manager will be chosen for the session.
+.TP 8
+.B \-indirect \fIhost-name\fP
+Enable XDMCP and send IndirectQuery packets to the specified host.
+.TP 8
+.B \-port \fIport-num\fP
+Use an alternate port number for XDMCP packets. Must be specified before
+any \-query, \-broadcast or \-indirect options.
+.TP 8
+.B \-class \fIdisplay-class\fP
+XDMCP has an additional display qualifier used in resource lookup for
+display-specific options. This option sets that value, by default it
+is "MIT-Unspecified" (not a very useful value).
+.TP 8
+.B \-cookie \fIxdm-auth-bits\fP
+When testing XDM-AUTHENTICATION-1, a private key is shared between the
+server and the manager. This option sets the value of that private
+data (not that it is very private, being on the command line!).
+.TP 8
+.B \-displayID \fIdisplay-id\fP
+Yet another XDMCP specific value, this one allows the display manager to
+identify each display so that it can locate the shared key.
+.SH XKEYBOARD OPTIONS
+X servers that support the XKEYBOARD extension accept the following options:
+.ig
+.TP 8
+.B \-xkbdir \fIdirectory\fP
+base directory for keyboard layout files
+..
+.TP 8
+.B \-xkbmap \fIfilename\fP
+keyboard description to load on startup
+.TP 8
+.B [+-]accessx
+enable(+) or disable(-) AccessX key sequences
+.TP 8
+.B \-ar1 \fImilliseconds\fP
+sets the length of time in milliseconds that a key must be depressed before
+autorepeat starts
+.TP 8
+.B \-ar2 \fImilliseconds\fP
+sets the length of time in milliseconds that should elapse between
+autorepeat-generated keystrokes
+.PP
+Many servers also have device-specific command line options. See the
+manual pages for the individual servers for more details.
+.SH SECURITY EXTENSION OPTIONS
+X servers that support the SECURITY extension accept the following option:
+.TP 8
+.B \-sp \fIfilename\fP
+causes
+the server to attempt to read and interpret filename as a security policy
+file with the format described below. The file is read at
+server startup and reread at each server reset.
+.PP
+The syntax of the security policy file is as follows.
+Notation: "*" means zero or more occurrences of the preceding element,
+and "+" means one or more occurrences. To interpret <foo/bar>, ignore
+the text after the /; it is used to distinguish between instances of
+<foo> in the next section.
+.PP
+.nf
+<policy file> ::= <version line> <other line>*
+
+<version line> ::= <string/v> '\en'
+
+<other line > ::= <comment> | <access rule> | <site policy> | <blank line>
+
+<comment> ::= # <not newline>* '\en'
+
+<blank line> ::= <space> '\en'
+
+<site policy> ::= sitepolicy <string/sp> '\en'
+
+<access rule> ::= property <property/ar> <window> <perms> '\en'
+
+<property> ::= <string>
+
+<window> ::= any | root | <required property>
+
+<required property> ::= <property/rp> | <property with value>
+
+<property with value> ::= <property/rpv> = <string/rv>
+
+<perms> ::= [ <operation> | <action> | <space> ]*
+
+<operation> ::= r | w | d
+
+<action> ::= a | i | e
+
+<string> ::= <dbl quoted string> | <single quoted string> | <unqouted string>
+
+<dbl quoted string> ::= <space> " <not dqoute>* " <space>
+
+<single quoted string> ::= <space> ' <not squote>* ' <space>
+
+<unquoted string> ::= <space> <not space>+ <space>
+
+<space> ::= [ ' ' | '\et' ]*
+
+Character sets:
+
+<not newline> ::= any character except '\en'
+<not dqoute> ::= any character except "
+<not squote> ::= any character except '
+<not space> ::= any character except those in <space>
+.fi
+.PP
+The semantics associated with the above syntax are as follows.
+.PP
+<version line>, the first line in the file, specifies the file format
+version. If the server does not recognize the version <string/v>, it
+ignores the rest of the file. The version string for the file format
+described here is "version-1" .
+.PP
+Once past the <version line>, lines that do not match the above syntax
+are ignored.
+.PP
+<comment> lines are ignored.
+.PP
+<sitepolicy> lines are currently ignored. They are intended to
+specify the site policies used by the XC-QUERY-SECURITY-1
+authorization method.
+.PP
+<access rule> lines specify how the server should react to untrusted
+client requests that affect the X Window property named <property/ar>.
+The rest of this section describes the interpretation of an
+<access rule>.
+.PP
+For an <access rule> to apply to a given instance of <property/ar>,
+<property/ar> must be on a window that is in the set of windows
+specified by <window>. If <window> is any, the rule applies to
+<property/ar> on any window. If <window> is root, the rule applies to
+<property/ar> only on root windows.
+.PP
+If <window> is <required property>, the following apply. If <required
+property> is a <property/rp>, the rule applies when the window also
+has that <property/rp>, regardless of its value. If <required
+property> is a <property with value>, <property/rpv> must also have
+the value specified by <string/rv>. In this case, the property must
+have type STRING and format 8, and should contain one or more
+null-terminated strings. If any of the strings match <string/rv>, the
+rule applies.
+.PP
+The definition of string matching is simple case-sensitive string
+comparison with one elaboration: the occurence of the character '*' in
+<string/rv> is a wildcard meaning "any string." A <string/rv> can
+contain multiple wildcards anywhere in the string. For example, "x*"
+matches strings that begin with x, "*x" matches strings that end with
+x, "*x*" matches strings containing x, and "x*y*" matches strings that
+start with x and subsequently contain y.
+.PP
+There may be multiple <access rule> lines for a given <property/ar>.
+The rules are tested in the order that they appear in the file. The
+first rule that applies is used.
+.PP
+<perms> specify operations that untrusted clients may attempt, and
+the actions that the server should take in response to those operations.
+.PP
+<operation> can be r (read), w (write), or d (delete). The following
+table shows how X Protocol property requests map to these operations
+in the X Consortium server implementation.
+.PP
+.nf
+GetProperty r, or r and d if delete = True
+ChangeProperty w
+RotateProperties r and w
+DeleteProperty d
+ListProperties none, untrusted clients can always list all properties
+.fi
+.PP
+<action> can be a (allow), i (ignore), or e (error). Allow means
+execute the request as if it had been issued by a trusted client.
+Ignore means treat the request as a no-op. In the case of
+GetProperty, ignore means return an empty property value if the
+property exists, regardless of its actual value. Error means do not
+execute the request and return a BadAtom error with the atom set to
+the property name. Error is the default action for all properties,
+including those not listed in the security policy file.
+.PP
+An <action> applies to all <operation>s that follow it, until the next
+<action> is encountered. Thus, irwad means ignore read and write,
+allow delete.
+.PP
+GetProperty and RotateProperties may do multiple operations (r and d,
+or r and w). If different actions apply to the operations, the most
+severe action is applied to the whole request; there is no partial
+request execution. The severity ordering is: allow < ignore < error.
+Thus, if the <perms> for a property are ired (ignore read, error
+delete), and an untrusted client attempts GetProperty on that property
+with delete = True, an error is returned, but the property value is
+not. Similarly, if any of the properties in a RotateProperties do not
+allow both read and write, an error is returned without changing any
+property values.
+.PP
+Here is an example security policy file.

+.SH "NETWORK CONNECTIONS"
+The X server supports client connections via a platform-dependent subset of
+the following transport types: TCP\/IP, Unix Domain sockets, DECnet,
+and several varieties of SVR4 local connections. See the DISPLAY
+NAMES section of the \fIX(1)\fP manual page to learn how to specify
+which transport type clients should try to use.
+.SH GRANTING ACCESS
+The X server implements a platform-dependent subset of the following
+authorization protocols: MIT-MAGIC-COOKIE-1, XDM-AUTHORIZATION-1,
+SUN-DES-1, and MIT-KERBEROS-5. See the \fIXsecurity(1)\fP manual page
+for information on the operation of these protocols.
+.PP
+Authorization data required by the above protocols is passed to the
+server in a private file named with the \fB\-auth\fP command line
+option. Each time the server is about to accept the first connection
+after a reset (or when the server is starting), it reads this file.
+If this file contains any authorization records, the local host is not
+automatically allowed access to the server, and only clients which
+send one of the authorization records contained in the file in the
+connection setup information will be allowed access. See the
+\fIXau\fP manual page for a description of the binary format of this
+file. See \fIxauth(1)\fP for maintenance of this file, and distribution
+of its contents to remote hosts.
+.PP
+The X server also uses a host-based access control list for deciding
+whether or not to accept connections from clients on a particular machine.
+If no other authorization mechanism is being used,
+this list initially consists of the host on which the server is running as
+well as any machines listed in the file \fI/etc/X\fBn\fI.hosts\fR, where
+\fBn\fP is the display number of the server. Each line of the file should
+contain either an Internet hostname (e.g. expo.lcs.mit.edu) or a DECnet
+hostname in double colon format (e.g. hydra::). There should be no leading
+or trailing spaces on any lines. For example:
+.sp
+.in +8
+.nf
+joesworkstation
+corporate.company.com
+star::
+bigcpu::
+.fi
+.in -8
+.PP
+Users can add or remove hosts from this list and enable or disable access
+control using the \fIxhost\fP command from the same machine as the server.
+.PP
+The X protocol intrinsically does not have any notion of window operation
+permissions or place any restrictions on what a client can do; if a program can
+connect to a display, it has full run of the screen.
+X servers that support the SECURITY extension fare better because clients
+can be designated untrusted via the authorization they use to connect; see
+the \fIxauth(1)\fP manual page for details. Restrictions are imposed
+on untrusted clients that curtail the mischief they can do. See the SECURITY

+.PP
+Sites that have better
+authentication and authorization systems might wish to make
+use of the hooks in the libraries and the server to provide additional
+security models.
+.SH SIGNALS
+The X server attaches special meaning to the following signals:
+.TP 8
+.I SIGHUP
+This signal causes the server to close all existing connections, free all
+resources, and restore all defaults. It is sent by the display manager
+whenever the main user's main application (usually an \fIxterm\fP or window
+manager) exits to force the server to clean up and prepare for the next
+user.
+.TP 8
+.I SIGTERM
+This signal causes the server to exit cleanly.
+.TP 8
+.I SIGUSR1
+This signal is used quite differently from either of the above. When the
+server starts, it checks to see if it has inherited SIGUSR1 as SIG_IGN
+instead of the usual SIG_DFL. In this case, the server sends a SIGUSR1 to
+its parent process after it has set up the various connection schemes.
+\fIXdm\fP uses this feature to recognize when connecting to the server
+is possible.
+.SH FONTS
+The X server
+can obtain fonts from directories and/or from font servers.
+The list of directories and font servers
+the X server uses when trying to open a font is controlled
+by the \fIfont path\fP.
+.LP
+The default font path is
+"<XRoot>/lib/X11/fonts/misc/,
+<XRoot>/lib/X11/fonts/Speedo/,
+<XRoot>/lib/X11/fonts/Type1/,
+<XRoot>/lib/X11/fonts/75dpi/,
+<XRoot>/lib/X11/fonts/100dpi/" .
+where <XRoot> refers to the root of the X11 install tree.
+.LP
+The font path can be set with the \fB\-fp\fP option or by \fIxset(1)\fP
+after the server has started.

+.TH Xvnc 1 "28 February 2003" "RealVNC Ltd" "Virtual Network Computing"
+.SH NAME
+Xvnc \- the X VNC server
+.SH SYNOPSIS
+.B Xvnc
+.RI [ options ]
+.RI : display#
+.SH DESCRIPTION
+.B Xvnc
+is the X VNC (Virtual Network Computing) server. It is based on a standard X
+server, but it has a "virtual" screen rather than a physical one. X
+applications display themselves on it as if it were a normal X display, but
+they can only be accessed via a VNC viewer - see \fBvncviewer\fP(1).
+
+So Xvnc is really two servers in one. To the applications it is an X server,
+and to the remote VNC users it is a VNC server. By convention we have arranged
+that the VNC server display number will be the same as the X server display
+number, which means you can use eg. snoopy:2 to refer to display 2 on machine
+"snoopy" in both the X world and the VNC world.
+
+The best way of starting \fBXvnc\fP is via the \fBvncserver\fP script. This
+sets up the environment appropriately and runs some X applications to get you
+going. See the manual page for \fBvncserver\fP(1) for more information.
+
+.SH OPTIONS
+.B Xvnc
+takes lots of options - running \fBXvnc -help\fP gives a list. Many of these
+are standard X server options, which are described in the \fBXserver\fP(1)
+manual page.
+
+.TP
+.B \-geometry \fIwidth\fPx\fIheight\fP
+Specify the size of the desktop to be created. Default is 640x480.
+
+.TP
+.B \-depth \fIdepth\fP
+Specify the pixel depth in bits of the desktop to be created. Default is 8,
+other possible values are 15, 16 and 24 - anything else is likely to cause
+strange behaviour by applications.
+
+.TP
+.B \-pixelformat \fIformat\fP
+Specify pixel format for server to use (BGRnnn or RGBnnn). The default for
+depth 8 is BGR233 (meaning the most significant two bits represent blue, the
+next three green, and the least significant three represent red), the default
+for depth 16 is RGB565 and for depth 24 is RGB888.
+
+.TP
+.B \-cc 3
+As an alternative to the default TrueColor visual, this allows you to run an
+Xvnc server with a PseudoColor visual (i.e. one which uses a colour map or
+palette), which can be useful for running some old X applications which only
+work on such a display. Note that viewing such a desktop can be painful
+because it usually results in a full-screen redraw every time an entry in the
+colour map changes. Values other than 3 (PseudoColor) and 4 (TrueColor) for
+the \-cc option may result in strange behaviour, and PseudoColor desktops must
+be 8 bits deep.
+
+.TP
+.B \-rfbport \fIport\fP
+Specifies the TCP port on which Xvnc listens for connections from viewers (the
+protocol used in VNC is called RFB - "remote framebuffer"). The default is
+5900 plus the display number.
+
+.TP
+.B \-rfbwait \fItime\fP
+Time in milliseconds to wait for a viewer which is blocking Xvnc. This is
+necessary because Xvnc is single-threaded and sometimes blocks until the viewer
+has finished sending or receiving a message - note that this does not mean an
+update will be aborted after this time. Default is 20000 (20 seconds).
+
+.TP
+.B \-nocursor
+Don't draw a cursor. This can be useful when debugging a viewer to make the
+updates drawn more predictable.
+
+.TP
+.B \-rfbauth \fIpasswd-file\fP
+Specifies the file containing the password used to authenticate viewers. The
+file is accessed each time a connection comes in, so it can be changed on the
+fly via \fBvncpasswd\fP(1).
+
+.TP
+.B \-httpd \fIdirectory\fP
+Run a mini-HTTP server which serves files from the given directory. Normally
+the directory will contain the classes for the Java viewer. In addition, files
+with a .vnc extension will have certain substitutions made so that a single
+installation of the Java VNC viewer can be served by separate instances of
+Xvnc.
+
+.TP
+.B \-httpport \fIport\fP
+Specifies the port on which the mini-HTTP server runs. Default is 5800 plus
+the display number.
+
+.TP
+.B \-deferupdate \fItime\fP
+Xvnc uses a "deferred update" mechanism which enhances performance in many
+cases. After any change to the framebuffer, Xvnc waits for this number of
+milliseconds (default 40) before sending an update to any waiting clients. This
+means that more changes tend to get coalesced together in a single
+update. Setting it to 0 results in the same behaviour as earlier versions of
+Xvnc, where the first change to the framebuffer causes an immediate update to
+any waiting clients.
+
+.TP
+.B \-economictranslate
+The server normally uses a lookup table for translating pixel values when the
+viewer requests a different format from the native one used by the server.
+This can use up to 256Kbytes per connected viewer, so if you have many viewers
+you may wish to specify this option which will save memory at the expense of a
+little bit of speed. Only relevant for 16-bit-deep desktops.
+
+.TP
+.B \-maxrects \fInum\fP
+Sets the maximum number of rectangles Xvnc will send in one update. If an
+update would consist of more than this many rectangles, then an update of a
+single bounding rectangle is sent instead. This makes sense because sending a
+large number of small rectangles is less efficient than sending one large
+rectangle, even when this means updating pixels which haven't actually changed.
+The default is 50.
+
+.TP
+.B \-desktop \fIdesktop-name\fP
+Each desktop has a name which may be displayed by the viewer. It defaults to
+"x11".
+
+.TP
+.B \-alwaysshared
+Always treat new clients as shared (i.e. ignore client's shared flag).
+
+.TP
+.B \-nevershared
+Never treat new clients as shared (i.e. ignore client's shared flag).
+
+.TP
+.B \-dontdisconnect
+Don't disconnect existing clients when a new "non-shared" connection comes
+in. Instead the new connection is refused. New "shared" connections are still
+allowed in the normal way.
+
+.TP
+.B \-localhost
+Only allow connections from the same machine. Useful if you use SSH and want to
+stop non-SSH connections from any other hosts. See the guide to using VNC with
+SSH on the web site.
+
+.TP
+.B \-inetd
+This significantly changes Xvnc's behaviour so that it can be launched from
+inetd. Instead of listening for TCP connections it uses its standard input and
+standard output as a connection to the VNC viewer. See the information on the
+extras page on the web site for details.

+
+ NON-SLOPED LINES
+ horizontal lines are always drawn left to right; we have to
+move the endpoints right by one after they're swapped.
+ horizontal lines will be confined to a single band of a
+region. the code finds that band (giving up if the lower
+bound of the band is above the line we're drawing); then it
+finds the first box in that band that contains part of the
+line. we clip the line to subsequent boxes in that band.
+ vertical lines are always drawn top to bottom (y-increasing.)
+this requires adding one to the y-coordinate of each endpoint
+after swapping.
+
+ SLOPED LINES
+ when clipping a sloped line, we bring the second point inside
+the clipping box, rather than one beyond it, and then add 1 to
+the length of the line before drawing it. this lets us use
+the same box for finding the outcodes for both endpoints. since
+the equation for clipping the second endpoint to an edge gives us
+1 beyond the edge, we then have to move the point towards the
+first point by one step on the major axis.
+ eventually, there will be a diagram here to explain what's going
+on. the method uses Cohen-Sutherland outcodes to determine
+outsideness, and a method similar to Pike's layers for doing the
+actual clipping.

+/*
+ * ==========================================================================
+ * Converted from mfb to support memory-mapped color framebuffer by smarks@sun,
+ * April-May 1987.
+ *
+ * The way I did the conversion was to consider each longword as an
+ * array of four bytes instead of an array of 32 one-bit pixels. So
+ * getbits() and putbits() retain much the same calling sequence, but
+ * they move bytes around instead of bits. Of course, this entails the
+ * removal of all of the one-bit-pixel dependencies from the other
+ * files, but the major bit-hacking stuff should be covered here.
+ *
+ * I've created some new macros that make it easier to understand what's
+ * going on in the pixel calculations, and that make it easier to change the
+ * pixel size.
+ *
+ * name explanation
+ * ---- -----------
+ * PSZ pixel size (in bits)
+ * PGSZ pixel group size (in bits)
+ * PGSZB pixel group size (in bytes)
+ * PGSZBMSK mask with lowest PGSZB bits set to 1
+ * PPW pixels per word (pixels per pixel group)
+ * PPWMSK mask with lowest PPW bits set to 1
+ * PLST index of last pixel in a word (should be PPW-1)
+ * PIM pixel index mask (index within a pixel group)
+ * PWSH pixel-to-word shift (should be log2(PPW))
+ * PMSK mask with lowest PSZ bits set to 1
+ *
+ *
+ * Here are some sample values. In the notation cfbA,B: A is PSZ, and
+ * B is PGSZB. All the other values are derived from these
+ * two. This table does not show all combinations!
+ *
+ * name cfb8,4 cfb24,4 cfb32,4 cfb8,8 cfb24,8 cfb32,8
+ * ---- ------ ------- ------ ------ ------ -------
+ * PSZ 8 24 32 8 24 32
+ * PGSZ 32 32 32 64 64 64
+ * PGSZB 4 4 4 8 8 8
+ * PGSZBMSK 0xF 0xF? 0xF 0xFF 0xFF 0xFF
+ * PPW 4 1 1 8 2 2
+ * PPWMSK 0xF 0x1 0x1 0xFF 0x3? 0x3
+ * PLST 3 0 0 7 1 1
+ * PIM 0x3 0x0 0x0 0x7 0x1? 0x1
+ * PWSH 2 0 0 3 1 1
+ * PMSK 0xFF 0xFFFFFF 0xFFFFFFFF 0xFF 0xFFFFFF 0xFFFFFFFF
+ *
+ *
+ * I have also added a new macro, PFILL, that takes one pixel and
+ * replicates it throughout a word. This macro definition is dependent
+ * upon pixel and word size; it doesn't use macros like PPW and so
+ * forth. Examples: for monochrome, PFILL(1) => 0xffffffff, PFILL(0) =>
+ * 0x00000000. For 8-bit color, PFILL(0x5d) => 0x5d5d5d5d. This macro
+ * is used primarily for replicating a plane mask into a word.
+ *
+ * Color framebuffers operations also support the notion of a plane
+ * mask. This mask determines which planes of the framebuffer can be
+ * altered; the others are left unchanged. I have added another
+ * parameter to the putbits and putbitsrop macros that is the plane
+ * mask.
+ * ==========================================================================

+ * PSZ needs to be defined before we get here. Usually it comes from a
+ * -DPSZ=foo on the compilation command line.

+/*
+ * PixelGroup is the data type used to operate on groups of pixels.
+ * We typedef it here to unsigned long with the assumption that you
+ * want to manipulate as many pixels at a time as you can. If unsigned
+ * long is not appropriate for your server, define it to something else
+ * before including this file. In this case you will also have to define
+ * PGSZB to the size in bytes of PixelGroup.

+
+cfbstartpartial[], cfbendpartial[]

+256 bytes of data seems a small price to pay -- code is smaller,
+and narrow things (e.g. window borders) go faster.
+
+the names may seem misleading; they are derived not from which end
+of the word the bits are turned on, but at which end of a scanline
+the table tends to be used.
+
+look at the tables and macros to understand boundary conditions.
+(careful readers will note that starttab[n] = ~endtab[n] for n != 0)
+
+-----------------------------------------------------------------------
+these two macros depend on the screen's bit ordering.
+in both of them x is a screen position. they are used to
+combine bits collected from multiple longwords into a
+single destination longword, and to unpack a single
+source longword into multiple destinations.
+
+SCRLEFT(dst, x)
+ takes dst[x, PPW] and moves them to dst[0, PPW-x]
+ the contents of the rest of dst are 0 ONLY IF
+ dst is UNSIGNED.
+ is cast as an unsigned.
+ this is a right shift on the VAX, left shift on
+ Sun and pc-rt.
+
+SCRRIGHT(dst, x)
+ takes dst[0,x] and moves them to dst[PPW-x, PPW]
+ the contents of the rest of dst are 0 ONLY IF
+ dst is UNSIGNED.
+ this is a left shift on the VAX, right shift on
+ Sun and pc-rt.
+
+
+the remaining macros are cpu-independent; all bit order dependencies
+are built into the tables and the two macros above.
+
+maskbits(x, w, startmask, endmask, nlw)
+ for a span of width w starting at position x, returns
+a mask for ragged pixels at start, mask for ragged pixels at end,
+and the number of whole longwords between the ends.
+
+maskpartialbits(x, w, mask)
+ works like maskbits(), except all the pixels are in the
+ same longword (i.e. (x&0xPIM + w) <= PPW)
+
+mask32bits(x, w, startmask, endmask, nlw)
+ as maskbits, but does not calculate nlw. it is used by
+ cfbGlyphBlt to put down glyphs <= PPW bits wide.
+
+getbits(psrc, x, w, dst)
+ starting at position x in psrc (x < PPW), collect w
+ pixels and put them in the screen left portion of dst.
+ psrc is a longword pointer. this may span longword boundaries.
+ it special-cases fetching all w bits from one longword.
+
+ +--------+--------+ +--------+
+ | | m |n| | ==> | m |n| |
+ +--------+--------+ +--------+
+ x x+w 0 w
+ psrc psrc+1 dst
+ m = PPW - x
+ n = w - m
+
+ implementation:
+ get m pixels, move to screen-left of dst, zeroing rest of dst;
+ get n pixels from next word, move screen-right by m, zeroing
+ lower m pixels of word.
+ OR the two things together.
+
+putbits(src, x, w, pdst, planemask)
+ starting at position x in pdst, put down the screen-leftmost
+ w bits of src. pdst is a longword pointer. this may
+ span longword boundaries.
+ it special-cases putting all w bits into the same longword.
+
+ +--------+ +--------+--------+
+ | m |n| | ==> | | m |n| |
+ +--------+ +--------+--------+
+ 0 w x x+w
+ dst pdst pdst+1
+ m = PPW - x
+ n = w - m
+
+ implementation:
+ get m pixels, shift screen-right by x, zero screen-leftmost x
+ pixels; zero rightmost m bits of *pdst and OR in stuff
+ from before the semicolon.
+ shift src screen-left by m, zero bits n-32;
+ zero leftmost n pixels of *(pdst+1) and OR in the
+ stuff from before the semicolon.
+
+putbitsrop(src, x, w, pdst, planemask, ROP)
+ like putbits but calls DoRop with the rasterop ROP (see cfb.h for
+ DoRop)
+
+getleftbits(psrc, w, dst)
+ get the leftmost w (w<=PPW) bits from *psrc and put them
+ in dst. this is used by the cfbGlyphBlt code for glyphs
+ <=PPW bits wide.

+ * There are four possible operations on each bit in the destination word,
+ *
+ * 1 2 3 4
+ *
+ * 0 0 0 1 1
+ * 1 0 1 0 1
+ *
+ * On examination of the reduced rop equation (dst = (dst & and) ^ xor),
+ * these four fall to reduced rops as follows:
+ *
+ * and 0 1 1 0
+ * xor 0 0 1 1
+ *
+ * or, (if 'and' is expensive) (dst = (dst | or) ^ xor)
+ *
+ * or 1 0 0 1
+ * xor 1 0 1 0
+ *
+ * The trouble with using this later equation is that trivial
+ * rasterop reduction is more difficult; some common rasterops
+ * use complicated expressions of xor/and instead of the simple
+ * ones while other common rasterops are not made any simpler:
+ *
+ * GXcopy: *dst = ~xor instead of *dst = xor
+ * GXand: *dst = *dst & ~or instead of *dst = *dst & and
+ * GXor: *dst = *dst | or instead of *dst = *dst | xor
+ * GXxor: *dst = *dst ^ xor instead of *dst = *dst ^ xor
+ *
+ * If you're really set on using this second mechanism, the changes
+ * are pretty simple.
+ *
+ * All that remains is to provide a mechanism for computing and/xor values
+ * based on the raster op and foreground value.
+ *
+ * The 16 rops fall as follows, with the associated reduced
+ * rop and/xor and or/xor values. The values in parenthesis following the
+ * reduced values gives an equation using the source value for
+ * the reduced value, and is one of {0, src, ~src, 1} as appropriate.

+ this works for fonts with glyphs <= 32 bits wide, on an
+ arbitrarily deep display. Use cfbTEGlyphBlt8 for 8 bit displays.
+
+ This should be called only with a terminal-emulator font;
+this means that the FIXED_METRICS flag is set, and that
+glyphbounds == charbounds.
+
+ in theory, this goes faster; even if it doesn't, it reduces the
+flicker caused by writing a string over itself with image text (since
+the background gets repainted per character instead of per string.)
+this seems to be important for some converted X10 applications.
+
+ Image text looks at the bits in the glyph and the fg and bg in the
+GC. it paints a rectangle, as defined in the protocol dcoument,
+and the paints the characters.

+File: .../x11/server/dix/BuiltInAtoms
+
+This file is of a fixed format and is used to generate both the file
+include/XAtom.h and dix/initatoms.c. Neither of those files should be
+edited directly. Changing the atoms in this file, or even the order in
+which they occur, is equivalent to forcing a new (minor) version number
+on the server. Take care.
+
+The format of the file is that each built in atom starts in column 1
+with no text, other than spaces and tabs, on that line other than a
+mandatory trailing "@" at the end of the line. For each atom (Foo)
+below the defines will be of the form
+ #define XA_Foo <n>
+and the string value of the atom will be "Foo".
+
+The comment lines in this file are not guaranteed to be accurate. To see the
+current truth, look at the Xlib documentation as well as the protocol spec.
+
+Atoms occur in five distinct name spaces within the protocol. Any particular
+atom may or may not have some client interpretation within each of the name
+spaces. For each of the built in atoms, the intended semantics and the space
+within which it is defined is indicated.
+
+Those name spaces are
+ Property names
+ Property types
+ Selections
+ Font properties
+ Type of a ClientMessage event (none built into server)
+
+For the font properties mentioned here, see the spec for more information.
+
+ -- Selections --
+
+PRIMARY @
+ Selection.
+SECONDARY @
+ Selection.
+
+ -- Property types and names --
+
+ARC @
+ Property type:
+ x, y: INT16
+ width, height: CARD16,
+ angle1, angle2: INT16
+ATOM @
+ Property type:
+ atom: ATOM
+BITMAP @
+ Property type:
+ bitmap: PIXMAP
+ This is asserted to be of depth 1.
+CARDINAL @
+ Property type:
+ card: CARD32 or CARD16 or CARD8
+ the datum size is dependent on the property format
+COLORMAP @
+ Property type:
+ colormap: COLORMAP
+CURSOR @
+ Property type:
+ cursor: CURSOR
+CUT_BUFFER0 @
+CUT_BUFFER1 @
+CUT_BUFFER2 @
+CUT_BUFFER3 @
+CUT_BUFFER4 @
+CUT_BUFFER5 @
+CUT_BUFFER6 @
+CUT_BUFFER7 @
+ Property name: (type: STRING)
+ Used to implement cut buffer ring, in particular Andrew uses
+ this mechanism. Anyone else using this sort of IPC mechanism
+ should use these properties.
+
+ Data is normally fetched and stored out of CUT_BUFFER0; the
+ RotateProperties request is used to rotate these buffers.
+DRAWABLE @
+ Property type:
+ drawable: DRAWABLE
+FONT @
+ Property type:
+ font: FONT
+INTEGER @
+ Property type:
+ card: INT32 or INT16 or INT8
+ the datum size is dependent on the property format
+PIXMAP @
+ Property type:
+ pixmap: PIXMAP
+POINT @
+ Property type:
+ x, y: INT16
+RECTANGLE @
+ Property type:
+ x, y: INT16
+ width, height: CARD16
+RESOURCE_MANAGER @
+ Property name: (type: STRING)
+ Contents of the user's resource manager data base.
+RGB_COLOR_MAP @
+ Property type:
+ colormap: COLORMAP
+ red-max: CARD32
+ red-mult: CARD32
+ green-max: CARD32
+ green-mult: CARD32
+ blue-max: CARD32
+ blue-mult: CARD32
+ base-pixel: CARD32
+
+ The fields `red_max', `green_max', and `blue_max' give the maximum
+ red, green, and blue values, respectively. Each color
+ coefficient ranges from 0 to its max, inclusive. For example,
+ a common colormap allocation is 3/3/2: 3 planes for red, 3
+ planes for green, and 2 planes for blue. Such a colormap would
+ have red_max == 7, green_max = 7, and blue_max = 3. An alternate
+ allocation that uses only 216 colors is red_max = 5, green_max =
+ 5, and blue_max = 5.
+
+ The fields `red_mult', `green_mult', and `blue_mult' give the
+ scale factors used to compose a full pixel value. (See next
+ paragraph.) For a 3/3/2 allocation red_mult might be 32,
+ green_mult might be 4, and blue_mult might be 1. For a
+ 6-colors-each allocation, red_mult might be 36, green_mult might
+ be 6, and blue_mult might be 1.
+
+ The field `base_pixel' gives the base pixel value used to
+ compose a full pixel value. Normally base_pixel is obtained
+ from a call to XAllocColorPlanes(). Given integer red, green,
+ and blue coefficients in their appropriate ranges, one can
+ compute a corresponding pixel value with the expression:
+
+ r * red_mult + g * green_mult + b * blue_mult + base_pixel
+
+ For gray-scale colormaps, only the colormap, red_max, red_mult,
+ and base_pixel fields are defined; the other fields are
+ ignored. To compute a gray-scale pixel value, use:
+
+ gray * red_mult + base_pixel
+
+ This is provided to allow applications to share color maps.
+
+RGB_BEST_MAP @
+RGB_BLUE_MAP @
+RGB_DEFAULT_MAP @
+RGB_GRAY_MAP @
+RGB_GREEN_MAP @
+RGB_RED_MAP @
+ Property name: (type: RGB_COLOR_MAP)
+ The needs of most applications can be met with five colormaps.
+ Polite applications may need only a small RGB space, and can
+ use a portion of the default color map. Applications doing
+ high-quality RGB rendering will need an entire colormap,
+ filled with as large an RGB space as possible, e.g. 332. For
+ color separations, an application may need maximum device
+ resolution for each of red, green, and blue, even if this
+ requires three renderings with three colormaps.
+
+ Each of the above five names would be used for sharing color
+ maps.
+STRING @
+ Property type:
+ sequence of Bytes
+VISUALID @
+ Property type:
+ visual: VISUALID
+WINDOW @
+ Property type:
+ window: WINDOW

+ 0x00000008 icon window hint
+ 0x00000010 icon position hint
+ values for initial-state
+ 0 unspecified -> application does not
+ care and WM should pick one.
+ 1 normal
+ 2 zoomed
+ 3 iconic
+ 4 inactive -> application believes
+ itself to be seldomly used. WM may wish to

+The following changes have been made to this directory since R3 (for
+a full description, see doc/Server/r4.tbl.ms):
+
+ o Windows restructured (memory reduction, devPrivates and speedups)
+ o GCs restructured (memory reduction, devPrivates and wrappers)
+ o Screens restructured (window ops merged in, devPrivates)
+ o Pixmaps restructured (drawable changes mostly)
+ o Cursors restructured (shares glyph bits now)
+ o Visuals restructured (screen index removed, fields rearranged)
+ o Devices restructured (input extension changes)
+ o Out of memory changes. Many interfaces now return OutOfMemory
+ status.
+ o Synchronous grab code rewritten. Should conform to our
+ understanding of the protocol now. Be careful when time
+ stamping events (don't allow time to run backwards).
+ o Resource types redesigned and rewritten.
+ o Internal fake color allocation routine for software cursors.

+ *
+ * This macro is used when we're trying to generate all 2^n combinations of
+ * bits in mask. What we're doing here is counting in binary, except that
+ * the bits we use to count may not be contiguous. This macro will be
+ * called 2^n times, returning a different value in bits each time. Then
+ * it will cause us to break out of a surrounding loop. (It will always be
+ * called from within a while loop.)
+ * On call: mask is the value we want to find all the combinations for
+ * base has 1 bit set where the least significant bit of mask is set
+ *
+ * For example,if mask is 01010, base should be 0010 and we count like this:
+ * 00010 (see this isn't so hard),
+ * then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so
+ * we add that to bits getting (0100 + 0100) =
+ * 01000 for our next value.
+ * then we add 0010 to get
+ * 01010 and we're done (easy as 1, 2, 3)

+ * This function was created as part of the Security extension
+ * implementation. The client performing the gc change must be passed so
+ * that access checks can be performed on any tiles, stipples, or fonts
+ * that are specified. ddxen can call this too; they should normally
+ * pass NullClient for the client since any access checking should have
+ * already been done at a higher level.
+ *
+ * Since we had to create a new function anyway, we decided to change the
+ * way the list of gc values is passed to eliminate the compiler warnings
+ * caused by the DoChangeGC interface. You can pass the values via pC32
+ * or pUnion, but not both; one of them must be NULL. If you don't need
+ * to pass any pointers, you can use either one:
+ *
+ * /* example calling dixChangeGC using pC32 parameter
+ * CARD32 v[2];
+ * v[0] = foreground;
+ * v[1] = background;
+ * dixChangeGC(client, pGC, GCForeground|GCBackground, v, NULL);
+ *
+ * /* example calling dixChangeGC using pUnion parameter;
+ * /* same effect as above
+ * ChangeGCVal v[2];
+ * v[0].val = foreground;
+ * v[1].val = background;
+ * dixChangeGC(client, pGC, GCForeground|GCBackground, NULL, v);
+ *
+ * However, if you need to pass a pointer to a pixmap or font, you MUST
+ * use the pUnion parameter.
+ *
+ * /* example calling dixChangeGC passing pointers in the value list
+ * ChangeGCVal v[2];
+ * v[0].val = FillTiled;
+ * v[1].ptr = pPixmap; /* pointer to a pixmap
+ * dixChangeGC(client, pGC, GCFillStyle|GCTile, NULL, v);
+ *
+ * Note: we could have gotten by with just the pUnion parameter, but on
+ * 64 bit machines that would have forced us to copy the value list that
+ * comes in the ChangeGC request.
+ *
+ * Ideally, we'd change all the DoChangeGC calls to dixChangeGC, but this
+ * is far too many changes to consider at this time, so we've only
+ * changed the ones that caused compiler warnings. New code should use
+ * dixChangeGC.

+ drawing caused by cursor movement. Whenever any drawing affects the
+ part of the screen where the cursor is, the cursor is removed first and
+ then the drawing is done (this is what the sprite routines test for).
+ Afterwards, however, we do not replace the cursor, even when the cursor
+ is logically being moved across the screen. We only draw the cursor
+ again just as we are about to send the client a framebuffer update.
+
+ We need to be careful when removing and drawing the cursor because of
+ their relationship with the normal drawing routines. The drawing
+ routines can invoke the cursor routines, but also the cursor routines
+ themselves end up invoking drawing routines.
+
+ Removing the cursor (rfbSpriteRemoveCursor) is eventually achieved by
+ doing a CopyArea from a pixmap to the screen, where the pixmap contains
+ the saved contents of the screen under the cursor. Before doing this,
+ however, we set cursorIsDrawn to FALSE. Then, when CopyArea is called,
+ it sees that cursorIsDrawn is FALSE and so doesn't feel the need to
+ (recursively!) remove the cursor before doing it.
+
+ Putting up the cursor (rfbSpriteRestoreCursor) involves a call to
+ PushPixels. While this is happening, cursorIsDrawn must be FALSE so
+ that PushPixels doesn't think it has to remove the cursor first.
+ Obviously cursorIsDrawn is set to TRUE afterwards.
+
+ Another problem we face is that drawing routines sometimes cause a
+ framebuffer update to be sent to the RFB client. When the RFB client is
+ already waiting for a framebuffer update and some drawing to the
+ framebuffer then happens, the drawing routine sees that the client is
+ ready, so it calls rfbSendFramebufferUpdate. If the cursor is not drawn
+ at this stage, it must be put up, and so rfbSpriteRestoreCursor is
+ called. However, if the original drawing routine was actually called
+ from within rfbSpriteRestoreCursor or rfbSpriteRemoveCursor we don't
+ want this to happen. So both the cursor routines set
+ dontSendFramebufferUpdate to TRUE, and all the drawing routines check
+ this before calling rfbSendFramebufferUpdate. */

+ * Machine dependent values:
+ * GLYPHPADBYTES should be chosen with consideration for the space-time
+ * trade-off. Padding to 0 bytes means that there is no wasted space
+ * in the font bitmaps (both on disk and in memory), but that access of
+ * the bitmaps will cause odd-address memory references. Padding to
+ * 2 bytes would ensure even address memory references and would
+ * be suitable for a 68010-class machine, but at the expense of wasted
+ * space in the font bitmaps. Padding to 4 bytes would be good
+ * for real 32 bit machines, etc. Be sure that you tell the font
+ * compiler what kind of padding you want because its defines are
+ * kept separate from this. See server/include/font.h for how
+ * GLYPHPADBYTES is used.
+ *
+ * Along with this, you should choose an appropriate value for
+ * GETLEFTBITS_ALIGNMENT, which is used in ddx/mfb/maskbits.h. This
+ * constant choses what kind of memory references are guarenteed during
+ * font access; either 1, 2 or 4, for byte, word or longword access,
+ * respectively. For instance, if you have decided to to have
+ * GLYPHPADBYTES == 4, then it is pointless for you to have a
+ * GETLEFTBITS_ALIGNMENT > 1, because the padding of the fonts has already
+ * guarenteed you that your fonts are longword aligned. On the other
+ * hand, even if you have chosen GLYPHPADBYTES == 1 to save space, you may
+ * also decide that the computing involved in aligning the pointer is more
+ * costly than an odd-address access; you choose GETLEFTBITS_ALIGNMENT == 1.
+ *
+ * Next, choose the tuning parameters which are appropriate for your
+ * hardware; these modify the behaviour of the raw frame buffer code
+ * in ddx/mfb and ddx/cfb. Defining these incorrectly will not cause
+ * the server to run incorrectly, but defining these correctly will
+ * cause some noticeable speed improvements:
+ *
+ * AVOID_MEMORY_READ - (8-bit cfb only)
+ * When stippling pixels on the screen (polytext and pushpixels),
+ * don't read long words from the display and mask in the
+ * appropriate values. Rather, perform multiple byte/short/long
+ * writes as appropriate. This option uses many more instructions
+ * but runs much faster when the destination is much slower than
+ * the CPU and at least 1 level of write buffer is availible (2
+ * is much better). Defined currently for SPARC and MIPS.
+ *
+ * FAST_CONSTANT_OFFSET_MODE - (cfb and mfb)
+ * This define is used on machines which have no auto-increment
+ * addressing mode, but do have an effectively free constant-offset
+ * addressing mode. Currently defined for MIPS and SPARC, even though
+ * I remember the cg6 as performing better without it (cg3 definitely
+ * performs better with it).
+ *
+ * LARGE_INSTRUCTION_CACHE -
+ * This define increases the number of times some loops are
+ * unrolled. On 68020 machines (with 256 bytes of i-cache),
+ * this define will slow execution down as instructions miss
+ * the cache frequently. On machines with real i-caches, this
+ * reduces loop overhead, causing a slight performance improvement.
+ * Currently defined for MIPS and SPARC
+ *
+ * FAST_UNALIGNED_READS -
+ * For machines with more memory bandwidth than CPU, this
+ * define uses unaligned reads for 8-bit BitBLT instead of doing
+ * aligned reads and combining the results with shifts and
+ * logical-ors. Currently defined for 68020 and vax.
+ * PLENTIFUL_REGISTERS -
+ * For machines with > 20 registers. Currently used for
+ * unrolling the text painting code a bit more. Currently
+ * defined for MIPS.
+ * SHARED_IDCACHE -
+ * For non-Harvard RISC machines, those which share the same
+ * CPU memory bus for instructions and data. This unrolls some
+ * solid fill loops which are otherwise best left rolled up.
+ * Currently defined for SPARC.

+in this file and maskbits.c, left and right refer to screen coordinates,
+NOT bit numbering in registers.

+starttab[n]

+endtab[n] =
+ bits[0,n-1] = 1 bits[n,PLST] = 0
+
+startpartial[], endpartial[]
+ these are used as accelerators for doing putbits and masking out
+bits that are all contained between longword boudaries. the extra
+256 bytes of data seems a small price to pay -- code is smaller,
+and narrow things (e.g. window borders) go faster.
+
+the names may seem misleading; they are derived not from which end
+of the word the bits are turned on, but at which end of a scanline
+the table tends to be used.
+
+look at the tables and macros to understand boundary conditions.
+(careful readers will note that starttab[n] = ~endtab[n] for n != 0)
+
+-----------------------------------------------------------------------
+these two macros depend on the screen's bit ordering.
+in both of them x is a screen position. they are used to
+combine bits collected from multiple longwords into a
+single destination longword, and to unpack a single
+source longword into multiple destinations.
+
+SCRLEFT(dst, x)
+ takes dst[x, PPW] and moves them to dst[0, PPW-x]
+ the contents of the rest of dst are 0.
+ this is a right shift on LSBFirst (forward-thinking)
+ machines like the VAX, and left shift on MSBFirst
+ (backwards) machines like the 680x0 and pc/rt.
+
+SCRRIGHT(dst, x)
+ takes dst[0,x] and moves them to dst[PPW-x, PPW]
+ the contents of the rest of dst are 0.
+ this is a left shift on LSBFirst, right shift
+ on MSBFirst.
+
+
+the remaining macros are cpu-independent; all bit order dependencies
+are built into the tables and the two macros above.
+
+maskbits(x, w, startmask, endmask, nlw)
+ for a span of width w starting at position x, returns
+a mask for ragged bits at start, mask for ragged bits at end,
+and the number of whole longwords between the ends.
+
+maskpartialbits(x, w, mask)
+ works like maskbits(), except all the bits are in the
+ same longword (i.e. (x&PIM + w) <= PPW)
+
+maskPPWbits(x, w, startmask, endmask, nlw)
+ as maskbits, but does not calculate nlw. it is used by
+ mfbGlyphBlt to put down glyphs <= PPW bits wide.
+
+-------------------------------------------------------------------
+
+NOTE
+ any pointers passed to the following 4 macros are
+ guranteed to be PPW-bit aligned.
+ The only non-PPW-bit-aligned references ever made are
+ to font glyphs, and those are made with getleftbits()
+ and getshiftedleftbits (qq.v.)
+
+ For 64-bit server, it is assumed that we will never have font padding
+ of more than 4 bytes. The code uses int's to access the fonts
+ intead of longs.
+
+getbits(psrc, x, w, dst)
+ starting at position x in psrc (x < PPW), collect w
+ bits and put them in the screen left portion of dst.
+ psrc is a longword pointer. this may span longword boundaries.
+ it special-cases fetching all w bits from one longword.
+
+ +--------+--------+ +--------+
+ | | m |n| | ==> | m |n| |
+ +--------+--------+ +--------+
+ x x+w 0 w
+ psrc psrc+1 dst
+ m = PPW - x
+ n = w - m
+
+ implementation:
+ get m bits, move to screen-left of dst, zeroing rest of dst;
+ get n bits from next word, move screen-right by m, zeroing
+ lower m bits of word.
+ OR the two things together.
+
+putbits(src, x, w, pdst)
+ starting at position x in pdst, put down the screen-leftmost
+ w bits of src. pdst is a longword pointer. this may
+ span longword boundaries.
+ it special-cases putting all w bits into the same longword.
+
+ +--------+ +--------+--------+
+ | m |n| | ==> | | m |n| |
+ +--------+ +--------+--------+
+ 0 w x x+w
+ dst pdst pdst+1
+ m = PPW - x
+ n = w - m
+
+ implementation:
+ get m bits, shift screen-right by x, zero screen-leftmost x
+ bits; zero rightmost m bits of *pdst and OR in stuff
+ from before the semicolon.
+ shift src screen-left by m, zero bits n-PPW;
+ zero leftmost n bits of *(pdst+1) and OR in the
+ stuff from before the semicolon.
+
+putbitsrop(src, x, w, pdst, ROP)
+ like putbits but calls DoRop with the rasterop ROP (see mfb.h for
+ DoRop)
+
+putbitsrrop(src, x, w, pdst, ROP)
+ like putbits but calls DoRRop with the reduced rasterop ROP
+ (see mfb.h for DoRRop)
+
+-----------------------------------------------------------------------
+ The two macros below are used only for getting bits from glyphs
+in fonts, and glyphs in fonts are gotten only with the following two
+mcros.
+ You should tune these macros toyour font format and cpu
+byte ordering.
+
+NOTE
+getleftbits(psrc, w, dst)
+ get the leftmost w (w<=32) bits from *psrc and put them
+ in dst. this is used by the mfbGlyphBlt code for glyphs
+ <=PPW bits wide.
+ psrc is declared (unsigned char *)
+
+ psrc is NOT guaranteed to be PPW-bit aligned. on many
+ machines this will cause problems, so there are several
+ versions of this macro.
+
+ this macro is called ONLY for getting bits from font glyphs,
+ and depends on the server-natural font padding.
+
+ for blazing text performance, you want this macro
+ to touch memory as infrequently as possible (e.g.
+ fetch longwords) and as efficiently as possible
+ (e.g. don't fetch misaligned longwords)
+
+getshiftedleftbits(psrc, offset, w, dst)
+ used by the font code; like getleftbits, but shifts the
+ bits SCRLEFT by offset.
+ this is implemented portably, calling getleftbits()
+ and SCRLEFT().
+ psrc is declared (unsigned char *).

+ ** window, the destination clip is also a single rectangle, and region
+ ** code can be avoided entirely. This is a big savings, since the region
+ ** code uses XAlloc() and makes many function calls.
+ **
+ ** In addition, if source is a pixmap, there is no need to call the
+ ** expensive miHandleExposures() routine. Instead, we simply return NULL.
+ **
+ ** Previously, drawing a pixmap into an unobscured window executed at least

+we make no assumptions about the heights, widths, or bearings
+of the glyphs. if we knew that the glyphs are all the same height,
+we could clip the tops and bottoms per clipping box, rather
+than per character per clipping box. if we knew that the glyphs'
+left and right bearings were wlle-behaved, we could clip a single
+character at the start, output until the last unclipped
+character, and then clip the last one. this is all straightforward
+to determine based on max-bounds and min-bounds from the font.
+ there is some inefficiency introduced in the per-character
+clipping to make what's going on clearer.
+
+ (it is possible, for example, for a font to be defined in which the
+next-to-last character in a font would be clipped out, but the last
+one wouldn't. the code below deals with this.)
+
+ Image text looks at the bits in the glyph and the fg and bg in the
+GC. it paints a rectangle, as defined in the protocol dcoument,
+and the paints the characters.

+/* single-pixel lines on a color frame buffer
+
+ NON-SLOPED LINES
+ horizontal lines are always drawn left to right; we have to
+move the endpoints right by one after they're swapped.
+ horizontal lines will be confined to a single band of a
+region. the code finds that band (giving up if the lower
+bound of the band is above the line we're drawing); then it
+finds the first box in that band that contains part of the
+line. we clip the line to subsequent boxes in that band.
+ vertical lines are always drawn top to bottom (y-increasing.)
+this requires adding one to the y-coordinate of each endpoint
+after swapping.
+
+ SLOPED LINES
+ when clipping a sloped line, we bring the second point inside
+the clipping box, rather than one beyond it, and then add 1 to
+the length of the line before drawing it. this lets us use
+the same box for finding the outcodes for both endpoints. since
+the equation for clipping the second endpoint to an edge gives us
+1 beyond the edge, we then have to move the point towards the
+first point by one step on the major axis.
+ eventually, there will be a diagram here to explain what's going
+on. the method uses Cohen-Sutherland outcodes to determine
+outsideness, and a method similar to Pike's layers for doing the
+actual clipping.

+/*
+ we should eventually special-case fixed-width fonts, although
+its more important for ImageText, which is meant for terminal
+emulators.
+
+ this works for fonts with glyphs <= 32 bits wide.
+
+ the clipping calculations are done for worst-case fonts.
+we make no assumptions about the heights, widths, or bearings
+of the glyphs. if we knew that the glyphs are all the same height,
+we could clip the tops and bottoms per clipping box, rather
+than per character per clipping box. if we knew that the glyphs'
+left and right bearings were well-behaved, we could clip a single
+character at the start, output until the last unclipped
+character, and then clip the last one. this is all straightforward
+to determine based on max-bounds and min-bounds from the font.
+ there is some inefficiency introduced in the per-character
+clipping to make what's going on clearer.
+
+ (it is possible, for example, for a font to be defined in which the
+next-to-last character in a font would be clipped out, but the last
+one wouldn't. the code below deals with this.)
+
+ PolyText looks at the fg color and the rasterop; mfbValidateGC
+swaps in the right routine after looking at the reduced ratserop
+in the private field of the GC.
+
+ the register allocations are provisional; in particualr startmask and
+endmask might not be the right things. pglyph, xoff, pdst, and tmpSrc
+are fairly obvious, though.
+
+ to avoid source proliferation, this file is compiled

+Three equations combine to describe the boundaries of the arc
+
+x^2/w^2 + y^2/h^2 = 1 ellipse itself
+(X-x)^2 + (Y-y)^2 = r^2 circle at (x, y) on the ellipse
+(Y-y) = (X-x)*w^2*y/(h^2*x) normal at (x, y) on the ellipse
+
+These lead to a quartic relating Y and y
+
+y^4 - (2Y)y^3 + (Y^2 + (h^4 - w^2*r^2)/(w^2 - h^2))y^2
+ - (2Y*h^4/(w^2 - h^2))y + (Y^2*h^4)/(w^2 - h^2) = 0
+
+The reducible cubic obtained from this quartic is
+
+z^3 - (3N)z^2 - 2V = 0
+
+where
+
+N = (Y^2 + (h^4 - w^2*r^2/(w^2 - h^2)))/6
+V = w^2*r^2*Y^2*h^4/(4 *(w^2 - h^2)^2)
+
+Let
+
+t = z - N
+p = -N^2
+q = -N^3 - V
+
+Then we get
+
+t^3 + 3pt + 2q = 0
+
+The discriminant of this cubic is
+
+D = q^2 + p^3
+
+When D > 0, a real root is obtained as
+
+z = N + cbrt(-q+sqrt(D)) + cbrt(-q-sqrt(D))
+
+When D < 0, a real root is obtained as
+
+z = N - 2m*cos(acos(-q/m^3)/3)
+
+where
+
+m = sqrt(|p|) * sign(q)
+
+Given a real root Z of the cubic, the roots of the quartic are the roots
+of the two quadratics
+
+y^2 + ((b+A)/2)y + (Z + (bZ - d)/A) = 0
+
+where
+
+A = +/- sqrt(8Z + b^2 - 4c)
+b, c, d are the cubic, quadratic, and linear coefficients of the quartic
+
+Some experimentation is then required to determine which solutions
+correspond to the inner and outer boundaries.

+ * When the server fails to allocate a backing store pixmap, if you want

+ */
+/* #define BSEAGER */
+
+/*-
+ * NOTES ON USAGE:
+ *
+ * The functions in this file implement a machine-independent backing-store
+ * scheme. To use it, the output library must do the following:
+ * - Provide a SaveAreas function that takes a destination pixmap, a
+ * region of the areas to save (in the pixmap's coordinate system)
+ * and the screen origin of the region. It should copy the areas from
+ * the screen into the pixmap.
+ * - Provide a RestoreAreas function that takes a source pixmap, a region
+ * of the areas to restore (in the screen's coordinate system) and the
+ * origin of the pixmap on the screen. It should copy the areas from
+ * the pixmap into the screen.
+ * - Provide a SetClipmaskRgn function that takes a gc and a region
+ * and merges the region into any CT_PIXMAP client clip that
+ * is specified in the GC. This routine is only needed if
+ * miValidateBackingStore will see CT_PIXMAP clip lists; not
+ * true for any of the sample servers (which convert the PIXMAP
+ * clip lists into CT_REGION clip lists; an expensive but simple
+ * to code option).
+ * - The function placed in a window's ClearToBackground vector must call
+ * pScreen->ClearBackingStore with the window, followed by
+ * the window-relative x and y coordinates, followed by the width and
+ * height of the area to be cleared, followed by the generateExposures
+ * flag. This has been taken care of in miClearToBackground.
+ * - Whatever determines GraphicsExpose events for the CopyArea and
+ * CopyPlane requests should call pWin->backStorage->ExposeCopy
+ * with the source and destination drawables, the GC used, a source-
+ * window-relative region of exposed areas, the source and destination
+ * coordinates and the bitplane copied, if CopyPlane, or 0, if
+ * CopyArea.
+ *
+ * JUSTIFICATION
+ * This is a cross between saving everything and just saving the
+ * obscued areas (as in Pike's layers.) This method has the advantage
+ * of only doing each output operation once per pixel, visible or
+ * invisible, and avoids having to do all the crufty storage
+ * management of keeping several separate rectangles. Since the
+ * ddx layer ouput primitives are required to draw through clipping
+ * rectangles anyway, sending multiple drawing requests for each of
+ * several rectangles isn't necessary. (Of course, it could be argued
+ * that the ddx routines should just take one rectangle each and
+ * get called multiple times, but that would make taking advantage of
+ * smart hardware harder, and probably be slower as well.)

+ * Let me try to explain what this routine is for:
+ *
+ * It's called from SlideAndSizeWindow whenever a window
+ * with backing store is resized. There are two separate
+ * possibilities:
+ *
+ * a) The window has ForgetGravity
+ *
+ * In this case, windx, windy will be 0 and oldClip will
+ * be NULL. This indicates that all of the window contents
+ * currently saved offscreen should be discarded, and the
+ * entire window exposed. TranslateBackingStore, then, should
+ * prepare a completely new backing store region based on the
+ * new window clipList and return that region for exposure.
+ *
+ * b) The window has some other gravity
+ *
+ * In this case, windx, windy will be set to the distance
+ * that the bits should move within the window. oldClip
+ * will be set to the old visible portion of the window.
+ * TranslateBackingStore, then, should adjust the backing
+ * store to accommodate the portion of the existing backing
+ * store bits which coorespond to backing store bits which
+ * will still be occluded in the new configuration. oldx,oldy
+ * are set to the old position of the window on the screen.
+ *
+ * Furthermore, in this case any contents of the screen which
+ * are about to become occluded should be fetched from the screen
+ * and placed in backing store. This is to avoid the eventual
+ * occlusion by the win gravity shifting the child window bits around
+ * on top of this window, and potentially losing information
+ *
+ * It's also called from SetShape, but I think (he says not
+ * really knowing for sure) that this code will even work
+ * in that case.

+when we validate the GC, and if we are painting a parent-relative
+background, the area we want to paint is in some other window.
+since we trust the code calling us to tell us to paint only areas
+that are really ours, we will temporarily give the window a
+clipList the size of the whole screen and an origin at (0,0).
+this more or less assumes that ddX code will do translation
+based on the window's absolute position, and that ValidateGC will
+look at clipList, and that no other fields from the
+window will be used. it's not possible to just draw
+in the root because it may be a different depth.
+
+to get the tile to align correctly we set the GC's tile origin to
+be the (x,y) of the window's upper left corner, after which we
+get the right bits when drawing into the root.
+
+because the clip_mask is being set to None, we may call DoChangeGC with
+fPointer set true, thus we no longer need to install the background or

+ * Created by Brian Kelleher; Oct 1985
+ *
+ * Include file for filled polygon routines.
+ *
+ * These are the data structures needed to scan
+ * convert regions. Two different scan conversion
+ * methods are available -- the even-odd method, and
+ * the winding number method.
+ * The even-odd rule states that a point is inside
+ * the polygon if a ray drawn from that point in any
+ * direction will pass through an odd number of
+ * path segments.
+ * By the winding number rule, a point is decided
+ * to be inside the polygon if a ray drawn from that
+ * point in any direction passes through a different
+ * number of clockwise and counter-clockwise path
+ * segments.
+ *
+ * These data structures are adapted somewhat from
+ * the algorithm in (Foley/Van Dam) for scan converting
+ * polygons.
+ * The basic algorithm is to start at the top (smallest y)
+ * of the polygon, stepping down to the bottom of
+ * the polygon by incrementing the y coordinate. We
+ * keep a list of edges which the current scanline crosses,
+ * sorted by x. This list is called the Active Edge Table (AET)
+ * As we change the y-coordinate, we update each entry in
+ * in the active edge table to reflect the edges new xcoord.
+ * This list must be sorted at each scanline in case
+ * two edges intersect.
+ * We also keep a data structure known as the Edge Table (ET),
+ * which keeps track of all the edges which the current
+ * scanline has not yet reached. The ET is basically a
+ * list of ScanLineList structures containing a list of
+ * edges which are entered at a given scanline. There is one
+ * ScanLineList per scanline at which an edge is entered.
+ * When we enter a new edge, we move it from the ET to the AET.
+ *
+ * From the AET, we can implement the even-odd rule as in
+ * (Foley/Van Dam).
+ * The winding number rule is a little trickier. We also
+ * keep the EdgeTableEntries in the AET linked by the
+ * nextWETE (winding EdgeTableEntry) link. This allows
+ * the edges to be linked just as before for updating
+ * purposes, but only uses the edges linked by the nextWETE
+ * link as edges representing spans of the polygon to
+ * drawn (as with the even-odd rule).

+ * The functions in this file implement the Region abstraction used extensively
+ * throughout the X11 sample server. A Region is simply a set of disjoint
+ * (non-overlapping) rectangles, plus an "extent" rectangle which is the
+ * smallest single rectangle that contains all the non-overlapping rectangles.
+ *
+ * A Region is implemented as a "y-x-banded" array of rectangles. This array
+ * imposes two degrees of order. First, all rectangles are sorted by top side
+ * y coordinate first (y1), and then by left side x coordinate (x1).
+ *
+ * Furthermore, the rectangles are grouped into "bands". Each rectangle in a
+ * band has the same top y coordinate (y1), and each has the same bottom y
+ * coordinate (y2). Thus all rectangles in a band differ only in their left
+ * and right side (x1 and x2). Bands are implicit in the array of rectangles:
+ * there is no separate list of band start pointers.
+ *
+ * The y-x band representation does not minimize rectangles. In particular,
+ * if a rectangle vertically crosses a band (the rectangle has scanlines in
+ * the y1 to y2 area spanned by the band), then the rectangle may be broken
+ * down into two or more smaller rectangles stacked one atop the other.
+ *
+ * ----------- -----------
+ * | | | | band 0
+ * | | -------- ----------- --------
+ * | | | | in y-x banded | | | | band 1
+ * | | | | form is | | | |
+ * ----------- | | ----------- --------
+ * | | | | band 2
+ * -------- --------
+ *
+ * An added constraint on the rectangles is that they must cover as much
+ * horizontal area as possible: no two rectangles within a band are allowed
+ * to touch.
+ *
+ * Whenever possible, bands will be merged together to cover a greater vertical
+ * distance (and thus reduce the number of rectangles). Two bands can be merged
+ * only if the bottom of one touches the top of the other and they have

+ * Written by Brian Kelleher; Jan 1985
+ *
+ * This file contains a few macros to help track
+ * the edge of a filled object. The object is assumed
+ * to be filled in scanline order, and thus the
+ * algorithm used is an extension of Bresenham's line
+ * drawing algorithm which assumes that y is always the
+ * major axis.
+ * Since these pieces of code are the same for any filled shape,
+ * it is more convenient to gather the library in one
+ * place, but since these pieces of code are also in
+ * the inner loops of output primitives, procedure call
+ * overhead is out of the question.
+ * See the author for a derivation if needed.

+ * In scan converting polygons, we want to choose those pixels
+ * which are inside the polygon. Thus, we add .5 to the starting
+ * x coordinate for both left and right edges. Now we choose the
+ * first pixel which is inside the pgon for the left edge and the
+ * first pixel which is outside the pgon for the right edge.
+ * Draw the left pixel, but not the right.
+ *
+ * How to add .5 to the starting x coordinate:
+ * If the edge is moving to the right, then subtract dy from the
+ * error term from the general form of the algorithm.
+ * If the edge is moving to the left, then add dy to the error term.
+ *
+ * The reason for the difference between edges moving to the left
+ * and edges moving to the right is simple: If an edge is moving
+ * to the right, then we want the algorithm to flip immediately.
+ * If it is moving to the left, then we don't want it to flip until
+ * we traverse an entire pixel.

+The bresenham error equation used in the mi/mfb/cfb line routines is:
+
+ e = error
+ dx = difference in raw X coordinates
+ dy = difference in raw Y coordinates
+ M = # of steps in X direction
+ N = # of steps in Y direction
+ B = 0 to prefer diagonal steps in a given octant,
+ 1 to prefer axial steps in a given octant
+
+ For X major lines:
+ e = 2Mdy - 2Ndx - dx - B
+ -2dx <= e < 0
+
+ For Y major lines:
+ e = 2Ndx - 2Mdy - dy - B
+ -2dy <= e < 0
+
+At the start of the line, we have taken 0 X steps and 0 Y steps,
+so M = 0 and N = 0:
+
+ X major e = 2Mdy - 2Ndx - dx - B
+ = -dx - B
+
+ Y major e = 2Ndx - 2Mdy - dy - B
+ = -dy - B
+
+At the end of the line, we have taken dx X steps and dy Y steps,
+so M = dx and N = dy:
+
+ X major e = 2Mdy - 2Ndx - dx - B
+ = 2dxdy - 2dydx - dx - B
+ = -dx - B
+ Y major e = 2Ndx - 2Mdy - dy - B
+ = 2dydx - 2dxdy - dy - B
+ = -dy - B
+
+Thus, the error term is the same at the start and end of the line.
+
+Let us consider clipping an X coordinate. There are 4 cases which
+represent the two independent cases of clipping the start vs. the
+end of the line and an X major vs. a Y major line. In any of these
+cases, we know the number of X steps (M) and we wish to find the
+number of Y steps (N). Thus, we will solve our error term equation.
+If we are clipping the start of the line, we will find the smallest
+N that satisfies our error term inequality. If we are clipping the
+end of the line, we will find the largest number of Y steps that
+satisfies the inequality. In that case, since we are representing
+the Y steps as (dy - N), we will actually want to solve for the
+smallest N in that equation.
+\f
+Case 1: X major, starting X coordinate moved by M steps
+
+ -2dx <= 2Mdy - 2Ndx - dx - B < 0
+ 2Ndx <= 2Mdy - dx - B + 2dx 2Ndx > 2Mdy - dx - B
+ 2Ndx <= 2Mdy + dx - B N > (2Mdy - dx - B) / 2dx
+ N <= (2Mdy + dx - B) / 2dx
+
+Since we are trying to find the smallest N that satisfies these
+equations, we should use the > inequality to find the smallest:
+
+ N = floor((2Mdy - dx - B) / 2dx) + 1
+ = floor((2Mdy - dx - B + 2dx) / 2dx)
+ = floor((2Mdy + dx - B) / 2dx)
+
+Case 1b: X major, ending X coordinate moved to M steps
+
+Same derivations as Case 1, but we want the largest N that satisfies
+the equations, so we use the <= inequality:
+
+ N = floor((2Mdy + dx - B) / 2dx)
+
+Case 2: X major, ending X coordinate moved by M steps
+
+ -2dx <= 2(dx - M)dy - 2(dy - N)dx - dx - B < 0
+ -2dx <= 2dxdy - 2Mdy - 2dxdy + 2Ndx - dx - B < 0
+ -2dx <= 2Ndx - 2Mdy - dx - B < 0
+ 2Ndx >= 2Mdy + dx + B - 2dx 2Ndx < 2Mdy + dx + B
+ 2Ndx >= 2Mdy - dx + B N < (2Mdy + dx + B) / 2dx
+ N >= (2Mdy - dx + B) / 2dx
+
+Since we are trying to find the highest number of Y steps that
+satisfies these equations, we need to find the smallest N, so
+we should use the >= inequality to find the smallest:
+
+ N = ceiling((2Mdy - dx + B) / 2dx)
+ = floor((2Mdy - dx + B + 2dx - 1) / 2dx)
+ = floor((2Mdy + dx + B - 1) / 2dx)
+
+Case 2b: X major, starting X coordinate moved to M steps from end
+
+Same derivations as Case 2, but we want the smallest number of Y
+steps, so we want the highest N, so we use the < inequality:
+
+ N = ceiling((2Mdy + dx + B) / 2dx) - 1
+ = floor((2Mdy + dx + B + 2dx - 1) / 2dx) - 1
+ = floor((2Mdy + dx + B + 2dx - 1 - 2dx) / 2dx)
+ = floor((2Mdy + dx + B - 1) / 2dx)
+\f
+Case 3: Y major, starting X coordinate moved by M steps
+
+ -2dy <= 2Ndx - 2Mdy - dy - B < 0
+ 2Ndx >= 2Mdy + dy + B - 2dy 2Ndx < 2Mdy + dy + B
+ 2Ndx >= 2Mdy - dy + B N < (2Mdy + dy + B) / 2dx
+ N >= (2Mdy - dy + B) / 2dx
+
+Since we are trying to find the smallest N that satisfies these
+equations, we should use the >= inequality to find the smallest:
+
+ N = ceiling((2Mdy - dy + B) / 2dx)
+ = floor((2Mdy - dy + B + 2dx - 1) / 2dx)
+ = floor((2Mdy - dy + B - 1) / 2dx) + 1
+
+Case 3b: Y major, ending X coordinate moved to M steps
+
+Same derivations as Case 3, but we want the largest N that satisfies
+the equations, so we use the < inequality:
+
+ N = ceiling((2Mdy + dy + B) / 2dx) - 1
+ = floor((2Mdy + dy + B + 2dx - 1) / 2dx) - 1
+ = floor((2Mdy + dy + B + 2dx - 1 - 2dx) / 2dx)
+ = floor((2Mdy + dy + B - 1) / 2dx)
+
+Case 4: Y major, ending X coordinate moved by M steps
+
+ -2dy <= 2(dy - N)dx - 2(dx - M)dy - dy - B < 0
+ -2dy <= 2dxdy - 2Ndx - 2dxdy + 2Mdy - dy - B < 0
+ -2dy <= 2Mdy - 2Ndx - dy - B < 0
+ 2Ndx <= 2Mdy - dy - B + 2dy 2Ndx > 2Mdy - dy - B
+ 2Ndx <= 2Mdy + dy - B N > (2Mdy - dy - B) / 2dx
+ N <= (2Mdy + dy - B) / 2dx
+
+Since we are trying to find the highest number of Y steps that
+satisfies these equations, we need to find the smallest N, so
+we should use the > inequality to find the smallest:
+
+ N = floor((2Mdy - dy - B) / 2dx) + 1
+
+Case 4b: Y major, starting X coordinate moved to M steps from end
+
+Same analysis as Case 4, but we want the smallest number of Y steps
+which means the largest N, so we use the <= inequality:
+
+ N = floor((2Mdy + dy - B) / 2dx)
+\f
+Now let's try the Y coordinates, we have the same 4 cases.
+
+Case 5: X major, starting Y coordinate moved by N steps
+
+ -2dx <= 2Mdy - 2Ndx - dx - B < 0
+ 2Mdy >= 2Ndx + dx + B - 2dx 2Mdy < 2Ndx + dx + B
+ 2Mdy >= 2Ndx - dx + B M < (2Ndx + dx + B) / 2dy
+ M >= (2Ndx - dx + B) / 2dy
+
+Since we are trying to find the smallest M, we use the >= inequality:
+
+ M = ceiling((2Ndx - dx + B) / 2dy)
+ = floor((2Ndx - dx + B + 2dy - 1) / 2dy)
+ = floor((2Ndx - dx + B - 1) / 2dy) + 1
+
+Case 5b: X major, ending Y coordinate moved to N steps
+
+Same derivations as Case 5, but we want the largest M that satisfies
+the equations, so we use the < inequality:
+
+ M = ceiling((2Ndx + dx + B) / 2dy) - 1
+ = floor((2Ndx + dx + B + 2dy - 1) / 2dy) - 1
+ = floor((2Ndx + dx + B + 2dy - 1 - 2dy) / 2dy)
+ = floor((2Ndx + dx + B - 1) / 2dy)
+
+Case 6: X major, ending Y coordinate moved by N steps
+
+ -2dx <= 2(dx - M)dy - 2(dy - N)dx - dx - B < 0
+ -2dx <= 2dxdy - 2Mdy - 2dxdy + 2Ndx - dx - B < 0
+ -2dx <= 2Ndx - 2Mdy - dx - B < 0
+ 2Mdy <= 2Ndx - dx - B + 2dx 2Mdy > 2Ndx - dx - B
+ 2Mdy <= 2Ndx + dx - B M > (2Ndx - dx - B) / 2dy
+ M <= (2Ndx + dx - B) / 2dy
+
+Largest # of X steps means smallest M, so use the > inequality:
+
+ M = floor((2Ndx - dx - B) / 2dy) + 1
+
+Case 6b: X major, starting Y coordinate moved to N steps from end
+
+Same derivations as Case 6, but we want the smallest # of X steps
+which means the largest M, so use the <= inequality:
+
+ M = floor((2Ndx + dx - B) / 2dy)
+\f
+Case 7: Y major, starting Y coordinate moved by N steps
+
+ -2dy <= 2Ndx - 2Mdy - dy - B < 0
+ 2Mdy <= 2Ndx - dy - B + 2dy 2Mdy > 2Ndx - dy - B
+ 2Mdy <= 2Ndx + dy - B M > (2Ndx - dy - B) / 2dy
+ M <= (2Ndx + dy - B) / 2dy
+
+To find the smallest M, use the > inequality:
+
+ M = floor((2Ndx - dy - B) / 2dy) + 1
+ = floor((2Ndx - dy - B + 2dy) / 2dy)
+ = floor((2Ndx + dy - B) / 2dy)
+
+Case 7b: Y major, ending Y coordinate moved to N steps
+
+Same derivations as Case 7, but we want the largest M that satisfies
+the equations, so use the <= inequality:
+
+ M = floor((2Ndx + dy - B) / 2dy)
+
+Case 8: Y major, ending Y coordinate moved by N steps
+
+ -2dy <= 2(dy - N)dx - 2(dx - M)dy - dy - B < 0
+ -2dy <= 2dxdy - 2Ndx - 2dxdy + 2Mdy - dy - B < 0
+ -2dy <= 2Mdy - 2Ndx - dy - B < 0
+ 2Mdy >= 2Ndx + dy + B - 2dy 2Mdy < 2Ndx + dy + B
+ 2Mdy >= 2Ndx - dy + B M < (2Ndx + dy + B) / 2dy
+ M >= (2Ndx - dy + B) / 2dy
+
+To find the highest X steps, find the smallest M, use the >= inequality:
+
+ M = ceiling((2Ndx - dy + B) / 2dy)
+ = floor((2Ndx - dy + B + 2dy - 1) / 2dy)
+ = floor((2Ndx + dy + B - 1) / 2dy)
+
+Case 8b: Y major, starting Y coordinate moved to N steps from the end
+
+Same derivations as Case 8, but we want to find the smallest # of X
+steps which means the largest M, so we use the < inequality:
+
+ M = ceiling((2Ndx + dy + B) / 2dy) - 1
+ = floor((2Ndx + dy + B + 2dy - 1) / 2dy) - 1
+ = floor((2Ndx + dy + B + 2dy - 1 - 2dy) / 2dy)
+ = floor((2Ndx + dy + B - 1) / 2dy)
+\f
+So, our equations are:
+
+ 1: X major move x1 to x1+M floor((2Mdy + dx - B) / 2dx)
+ 1b: X major move x2 to x1+M floor((2Mdy + dx - B) / 2dx)
+ 2: X major move x2 to x2-M floor((2Mdy + dx + B - 1) / 2dx)
+ 2b: X major move x1 to x2-M floor((2Mdy + dx + B - 1) / 2dx)
+
+ 3: Y major move x1 to x1+M floor((2Mdy - dy + B - 1) / 2dx) + 1
+ 3b: Y major move x2 to x1+M floor((2Mdy + dy + B - 1) / 2dx)
+ 4: Y major move x2 to x2-M floor((2Mdy - dy - B) / 2dx) + 1
+ 4b: Y major move x1 to x2-M floor((2Mdy + dy - B) / 2dx)
+
+ 5: X major move y1 to y1+N floor((2Ndx - dx + B - 1) / 2dy) + 1
+ 5b: X major move y2 to y1+N floor((2Ndx + dx + B - 1) / 2dy)
+ 6: X major move y2 to y2-N floor((2Ndx - dx - B) / 2dy) + 1
+ 6b: X major move y1 to y2-N floor((2Ndx + dx - B) / 2dy)
+
+ 7: Y major move y1 to y1+N floor((2Ndx + dy - B) / 2dy)
+ 7b: Y major move y2 to y1+N floor((2Ndx + dy - B) / 2dy)
+ 8: Y major move y2 to y2-N floor((2Ndx + dy + B - 1) / 2dy)
+ 8b: Y major move y1 to y2-N floor((2Ndx + dy + B - 1) / 2dy)
+
+We have the following constraints on all of the above terms:
+
+ 0 < M,N <= 2^15 2^15 can be imposed by miZeroClipLine
+ 0 <= dx/dy <= 2^16 - 1
+ 0 <= B <= 1
+
+The floor in all of the above equations can be accomplished with a
+simple C divide operation provided that both numerator and denominator
+are positive.
+
+Since dx,dy >= 0 and since moving an X coordinate implies that dx != 0
+and moving a Y coordinate implies dy != 0, we know that the denominators
+are all > 0.
+
+For all lines, (-B) and (B-1) are both either 0 or -1, depending on the
+bias. Thus, we have to show that the 2MNdxy +/- dxy terms are all >= 1
+or > 0 to prove that the numerators are positive (or zero).
+
+For X Major lines we know that dx > 0 and since 2Mdy is >= 0 due to the
+constraints, the first four equations all have numerators >= 0.
+
+For the second four equations, M > 0, so 2Mdy >= 2dy so (2Mdy - dy) >= dy
+So (2Mdy - dy) > 0, since they are Y major lines. Also, (2Mdy + dy) >= 3dy
+or (2Mdy + dy) > 0. So all of their numerators are >= 0.
+
+For the third set of four equations, N > 0, so 2Ndx >= 2dx so (2Ndx - dx)
+>= dx > 0. Similarly (2Ndx + dx) >= 3dx > 0. So all numerators >= 0.
+
+For the fourth set of equations, dy > 0 and 2Ndx >= 0, so all numerators
+are > 0.
+
+To consider overflow, consider the case of 2 * M,N * dx,dy + dx,dy. This
+is bounded <= 2 * 2^15 * (2^16 - 1) + (2^16 - 1)
+ <= 2^16 * (2^16 - 1) + (2^16 - 1)
+ <= 2^32 - 2^16 + 2^16 - 1
+ <= 2^32 - 1
+Since the (-B) and (B-1) terms are all 0 or -1, the maximum value of
+the numerator is therefore (2^32 - 1), which does not overflow an unsigned
+32 bit variable.

+ alloca -- (mostly) portable public-domain implementation -- D A Gwyn
+
+ This implementation of the PWB library alloca() function,
+ which is used to allocate space off the run-time stack so
+ that it is automatically reclaimed upon procedure exit,
+ was inspired by discussions with J. Q. Johnson of Cornell.
+
+ It should work under any C implementation that uses an
+ actual procedure stack (as opposed to a linked list of
+ frames). There are some preprocessor constants that can
+ be defined when compiling for your specific system, for
+ improved efficiency; however, the defaults should be okay.
+
+ The general concept of this implementation is to keep
+ track of all alloca()-allocated blocks, and reclaim any
+ that are found to be deeper in the stack than the current
+ invocation. This heuristic does not reclaim storage as
+ soon as it becomes invalid, but it will do so eventually.
+
+ As a special case, alloca(0) reclaims storage without
+ allocating any. It is a good idea to use alloca(0) in
+ your main control loop, etc. to force garbage collection.

+ * Conclusions: more than the half of all allocations are <= 32 bytes.
+ * But of these about 150,000 blocks, only a maximum of about 6,000 are
+ * allocated together (including memory leaks..).
+ * On the other side, only 935 of the 191573 or 0.5% were larger than 8kB
+ * (362 or 0.2% larger than 16k).
+ *
+ * What makes the server really grow is the fragmentation of the heap,
+ * and the fact that it can't shrink.
+ * To cure this, we do the following:
+ * - large blocks (>=11k) are mmapped on xalloc, and unmapped on xfree,
+ * so we don't need any free lists etc.
+ * As this needs 2 system calls, we only do this for the quite
+ * infrequent large (>=11k) blocks.
+ * - instead of reinventing the wheel, we use system malloc for medium
+ * sized blocks (>256, <11k).
+ * - for small blocks (<=256) we use an other approach:
+ * As we need many small blocks, and most ones for a short time,
+ * we don't go through the system malloc:
+ * for each fixed sizes a seperate list of free blocks is kept.
+ * to KISS (Keep it Small and Simple), we don't free them
+ * (not freeing a block of 32 bytes won't be worse than having fragmented
+ * a larger area on allocation).
+ * This way, we (almost) allways have a fitting free block right at hand,
+ * and don't have to walk any lists.

+
+ X Registry
+
+The X Consortium is maintaining a registry of certain X-related items, to
+aid in avoiding conflicts and to aid in sharing of such items. Requests to
+register items, or questions about registration, should be addressed to
+ xregistry@x.org
+or to
+ Registry
+ X Consortium
+ 201 Broadway
+ Cambridge MA 02139-1955
+ USA
+
+Electronic mail will be acknowledged upon receipt. Please allow up to 4 weeks
+for a formal response to registration and inquiries.
+
+The registry is published as part of the X software distribution from the
+X Consortium. It is also usually available by sending a message to
+xstuff@x.org. The message can have a subject line and no body, or a
+single-line body and no subject, in either case the line looking like:
+ send docs registry
+
+All registered items must have the postal address of someone responsible for
+the item, or a reference to a document describing the item and the postal
+address of where to write to obtain the document.
+
+Registration of conflicting items will not be permitted (the same value will
+not be assigned two different meanings) except where explicitly indicated.
+
+1. ORGANIZATION NAMES
+
+These should generally be used as prefixes for other registered names.

+Only "private" keysyms (with 29th bit set) can be registered by organizations;
+standard keysyms must be approved by the Consortium. Since keysym numeric
+values are explicitly private, we will permit (but not encourage) conflicting
+registration here.
