60<h2>DESCRIPTION</h2>
61
62
63<p style="margin-left:11%; margin-top: 1em">These routines
64are provided for writing portable software that uses
65<i>libtiff</i>; they hide any memory-management related
66issues, such as dealing with segmented architectures found
67on 16-bit machines.</p>
68
69
70<p style="margin-left:11%; margin-top: 1em"><i>_TIFFmalloc</i>
71and <i>_TIFFrealloc</i> are used to dynamically allocate and
72reallocate memory used by <i>libtiff</i>; such as memory
73passed into the I/O routines. Memory allocated through these
74interfaces is released back to the system using the
75<i>_TIFFfree</i> routine.</p>
76
77<p style="margin-left:11%; margin-top: 1em">Memory
78allocated through one of the above interfaces can be set to
79a known value using <i>_TIFFmemset</i>, copied to another
80memory location using <i>_TIFFmemcpy</i>, or compared for
81equality using <i>_TIFFmemcmp</i>. These routines conform to
82the equivalent <small>ANSI</small> C routines:
83<i>memset</i>, <i>memcpy</i>, and <i>memcmp</i>,
84repsectively.</p>
