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.
