<p>The <strong><em>gai_strerror()</em></strong> function retrieves a text
string that describes a return value received from calling the <a href=
"getaddrinfo.htm">getaddrinfo()</a> or <a href=
"getnameinfo.htm">getnameinfo()</a> API.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>ecode</strong></dt>
<dd>(Input) The return value received from <a href=
"getaddrinfo.htm">getaddrinfo()</a> or <a href=
"getnameinfo.htm">getnameinfo()</a>.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>No authorization is required.</p>
<br>
<h3>Return Value</h3>
<p><strong>gai_strerror()</strong> returns a pointer to the return value
text.</p>
<br>
<h3>Usage Notes</h3>
<ol>
<li><strong>gai_strerror()</strong> returns a pointer to the string. The
null-terminated string is stored in the CCSID of the job. If the job is 65535
and the string is something other than EBCDIC single byte or EBCDIC mixed, the
text is converted to the default job CCSID.<br><br></li>
<li>If an <em>ecode</em> is specified for which there is no corresponding
description, an Unknown Error string is returned.<br><br></li>
<li>The null-terminated string addressed by the pointer returned is overlayed
by subsequent invocations of the <strong>gai_strerror()</strong> API from
within the same thread.</li>
</ol>
