## 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.
