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