<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>

<h3>Parameters</h3>

<dl>

|
|
<dt><strong>ecode</strong></dt>
|

<dd>(Input) The return value received from <a href=

<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>

<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>
