NAME
TIFFmemory - memory management-related functions for use with TIFF files
SYNOPSIS
#include <tiffio.h>
- void *_TIFFmalloc(tmsize_t size)
- void *_TIFFrealloc(void *buffer, tmsize_t size)
- void _TIFFfree(void *buffer)
- void _TIFFmemset(void *s, int c, tmsize_t n)
- void _TIFFmemcpy(void *dest, const void *src, tmsize_t n)
- int _TIFFmemcmp(const void *s1, const void *s2, tmsize_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, tmsize_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 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 C routines: memset(), memcpy(), memcmp(), respectively.
_TIFFCheckMalloc() and _TIFFCheckRealloc() are checking for integer overflow before calling _TIFFmalloc() and _TIFFrealloc(), respectively.
DIAGNOSTICS
None.
