<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol type="1">
|
||
|
|
<li>When you develop in C-based languages, the prototypes for the 64-bit APIs
|
||
|
|
normally are hidden. To use the <strong>mmap64()</strong> API, you must compile
|
||
|
|
the source with the _LARGE_FILE_API macro defined.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>All of the usage notes for <strong>mmap()</strong> apply to <strong>
|

mmap64()</strong>.</li>
