<p>The <strong>gsk_strerror()</strong> function is used to retrieve an error
message and associated text string that describes a return value that was
returned from calling a GSKit API.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>gsk_return_value</strong>&nbsp;(Input)&nbsp;</dt>
<dd>The return value received from a GSKit API.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>No authorization is required.</p>
<br>
<h3>Return Value</h3>
<p><strong>gsk_strerror()</strong> returns a pointer to the return value
text.</p>
<br>
<h3>Usage Notes</h3>
<ol>
<li><strong>gsk_strerror()</strong> returns a pointer to the string. The
null-terminated string is stored in the CCSID of the job.<br>
<br>
</li>
<li>If a <em>gsk_return_value</em> is specified for which there is no
corresponding description, an Unknown Error string is returned.</li>
