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.
