<p><strong>Synopsis</strong>
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">#include <stdlib.h>
|
||
|
|
void _Exit(int <var>code</var>);
|
||
|
|
|

|
|
</pre></div>

|
|
<p><strong>Description</strong><br>
|
||
|
|
Use <code>_Exit</code> to return control from a program to the host operating
|
||
|
|
environment. Use the argument <var>code</var> to pass an exit status to the
|
||
|
|
operating environment: two particular values, <code>EXIT_SUCCESS</code> and
|
||
|
|
<code>EXIT_FAILURE</code>, are defined in ‘<code>stdlib.h</code>’ to indicate success or
|
||
|
|
failure in a portable fashion.
|
||
|
|
</p>
|
||
|
|
<p><code>_Exit</code> differs from <code>exit</code> in that it does not run any
|
||
|
|
application-defined cleanup functions registered with <code>atexit</code> and
|
||
|
|
it does not clean up files and streams. It is identical to <code>_exit</code>.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
<code>_Exit</code> does not return to its caller.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>_Exit</code> is defined by the C99 standard.
|
||
|
|
</p>
|
||
|
|
<p>Supporting OS subroutines required: <code>_exit</code>.
|
||
|
|
