NAME

TIFFmemory - memory management-related functions for use with TIFF files

SYNOPSIS

#include <tiffio.h>

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.
