|
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> |
