_TIFFmalloc, _TIFFrealloc, _TIFFfree, _TIFFmemset,

_TIFFmemcpy, _TIFFmemcmp, − memory management-related

functions for use with <small>TIFF</small> files

SYNOPSIS

       cols="2" cellspacing="0" cellpadding="0">

#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

int _TIFFmemcmp(const tdata_t s1, const

tdata_t s2, tsize_t n);

DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

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 <small>ANSI</small> C

routines: memset, memcpy, and memcmp,

repsectively.
