<p><strong>Synopsis</strong>
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">#include <stdio.h>
|
||
|
|
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>.
|
||
|
