<a name="index-psignal"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;stdio.h&gt;
void psignal(int <var>signal</var>, const char *<var>prefix</var>);

</pre></div>
<p><strong>Description</strong><br>
Use <code>psignal</code> to print (on standard error) a signal message
corresponding to the value of the signal number <var>signal</var>.
Unless you use <code>NULL</code> as the value of the argument <var>prefix</var>, the
signal message will begin with the string at <var>prefix</var>, followed by a
colon and a space (<code>: </code>). The remainder of the signal message is one
of the strings described for <code>strsignal</code>.
</p>
<br>
<p><strong>Returns</strong><br>
<code>psignal</code> returns no result.
</p>
<br>
<p><strong>Portability</strong><br>
POSIX.1-2008 requires <code>psignal</code>, but the strings issued vary from one
implementation to another.
</p>
<p>Supporting OS subroutines required: <code>close</code>, <code>fstat</code>, <code>isatty</code>,
<code>lseek</code>, <code>read</code>, <code>sbrk</code>, <code>write</code>.
</p>
