MEMORY(3TIFF)                                                    MEMORY(3TIFF)



NAME
       _TIFFmalloc, _TIFFrealloc, _TIFFfree, _TIFFmemset, _TIFFmemcpy,
       _TIFFmemcmp, - memory management-related functions for use with TIFF
       files

SYNOPSIS
       #include <tiffio.h>

       tdata_t _TIFFmalloc(tsize_t size);
       tdata_t _TIFFrealloc(tdata_t buffer, tsize_t size);
       void _TIFFfree(tdata_t buffer);
       void _TIFFmemset(tdata_t s, int c, tsize_t n);
       void _TIFFmemcpy(tdata_t dest, const tdata_t src, tsize_t n);
       int _TIFFmemcmp(const tdata_t s1, const tdata_t s2, tsize_t n);

DESCRIPTION
       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.

DIAGNOSTICS
       None.
