39 * This wrapper around realloc() will free the input pointer when
40 * realloc() returns NULL. The use case ptr = realloc(ptr, newsize) will
41 * cause a memory leak when ptr pointed to a heap allocation before,
42 * leaving the buffer allocated but unreferenced. vlc_realloc() is a
43 * drop-in replacement for that use case (and only that use case).
