_TIFFmalloc, \c _TIFFrealloc, \c _TIFFfree, \c _TIFFmemset, \c _TIFFmemcpy, \c _TIFFmemcmp, \c - memory management-related functions for use with TIFF files "#include <tiffio.h>" "tdata_t _TIFFmalloc(tsize_t " size ");"

"tdata_t _TIFFrealloc(tdata_t " buffer ", tsize_t " size ");"

"void _TIFFfree(tdata_t " buffer ");"

These routines are provided for writing portable software that uses libtiff ; they hide any memory-management related issues, such as dealing with segmented architectures found on 16-bit machines.

_TIFFmalloc and _TIFFrealloc are used to dynamically allocate and reallocate memory used by libtiff ; such as memory passed into the I/O routines. Memory allocated through these interfaces is released back to the system using the _TIFFfree routine.

Memory allocated through one of the above interfaces can be set to a known value using _TIFFmemset , copied to another memory location using _TIFFmemcpy , or compared for equality using _TIFFmemcmp . These routines conform to the equivalent ANSI C routines: memset , memcpy , and memcmp , repsectively.
