<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">These routines
are provided for writing portable software that uses
<i>libtiff</i>; they hide any memory-management related
issues, such as dealing with segmented architectures found
on 16-bit machines.</p>
<p style="margin-left:11%; margin-top: 1em"><i>_TIFFmalloc</i>
and <i>_TIFFrealloc</i> are used to dynamically allocate and
reallocate memory used by <i>libtiff</i>; such as memory
passed into the I/O routines. Memory allocated through these
interfaces is released back to the system using the
<i>_TIFFfree</i> routine.</p>
<p style="margin-left:11%; margin-top: 1em">Memory
allocated through one of the above interfaces can be set to
a known value using <i>_TIFFmemset</i>, copied to another
memory location using <i>_TIFFmemcpy</i>, or compared for
equality using <i>_TIFFmemcmp</i>. These routines conform to
the equivalent <small>ANSI</small> C routines:
<i>memset</i>, <i>memcpy</i>, and <i>memcmp</i>,
respectively.</p>
