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

|
|
<p><strong>Description</strong><br>
|
||
|
|
Use <code>abort</code> to signal that your program has detected a condition it
|
||
|
|
cannot deal with. Normally, <code>abort</code> ends your program’s execution.
|
||
|
|
</p>
|
||
|
|
<p>Before terminating your program, <code>abort</code> raises the exception <code>SIGABRT</code>
|
||
|
|
(using ‘<code>raise(SIGABRT)</code>’). If you have used <code>signal</code> to register
|
||
|
|
an exception handler for this condition, that handler has the
|
||
|
|
opportunity to retain control, thereby avoiding program termination.
|
||
|
|
</p>
|
||
|
|
<p>In this implementation, <code>abort</code> does not perform any stream- or
|
||
|
|
file-related cleanup (the host environment may do so; if not, you can
|
||
|
|
arrange for your program to do its own cleanup with a <code>SIGABRT</code>
|
||
|
|
exception handler).
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
<code>abort</code> does not return to its caller.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
ANSI C requires <code>abort</code>.
|
||
|
|
</p>
|
||
|
|
<p>Supporting OS subroutines required: <code>_exit</code> and optionally, <code>write</code>.
|
||
