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