NAME
TIFFmemory - 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_ts2, tsize_t n)
void *_TIFFCheckMalloc(TIFF *tif, tmsize_t nmemb, tmsize_t elem_size,
const char *what)
void *_TIFFCheckRealloc(TIFF *tif, void *buffer, tmsize_t nmemb, tm-
size_t elem_size, const char *what)
DESCRIPTION
These routines are provided for writing portable software that uses
libtiff; they hide any memory-management related issues, such as deal-
ing 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 us-
ing _TIFFmemcpy(), or compared for equality using _TIFFmemcmp(). These
routines conform to the equivalent C routines: memset(), memcpy(), mem-
cmp(), respectively.
_TIFFCheckMalloc() and _TIFFCheckRealloc() are checking for integer
overflow before calling _TIFFmalloc() and _TIFFrealloc(), respectively.
DIAGNOSTICS
None.
