NAME

_TIFFmalloc, _TIFFrealloc, _TIFFfree, _TIFFmemset, _TIFFmemcpy, _TIFFmemcmp, - memory management-related functions for use with 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

C routines: memset, memcpy, and memcmp, repsectively.

DIAGNOSTICS

None.
