<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>
