<h2>endnetent_r()--Close Network Database</h2>
<div class="box" style="width: 60%;">
<br>
&nbsp;&nbsp;Syntax<br>
<pre>
#include &lt;netdb.h&gt;
int endnetent_r(struct netent_data
*<em>netent_data_struct_addr</em>)
</pre>
<br>
&nbsp;&nbsp;Service Program Name: QSOSRV2<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Default Public Authority: *USE<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Threadsafe: Yes<br>
<!-- iddvc RMBR -->
<br>
</div>
<p>The <em>endnetent_r()</em> function is used to close the network database
file. The file is opened by those functions that retrieve information about a
network (for example, <em>getnetent_r()</em>).</p>
<h3>Parameters</h3>
<dl>
<dt>struct netent_data *<strong>netent_data_struct_addr</strong>
&nbsp;(input)&nbsp;</dt>
<dd>Specifies the pointer to the netent_data structure, which is used to pass
and preserve results between function calls. The field net_control_blk in the
netent_data structure must be initialized with hexadecimal zeros before its
initial use. If compatibility with other platforms is required, then the entire
netent_data structure must be initialized with hexadecimal zeros before initial
use.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>No authorization is required.</p>
<br>
<h3>Return Value</h3>
<p>The <em>endnetent_r()</em> function returns an integer. Possible values
are:</p>
<ul>
<li>-1 (unsuccessful call)<br>
<br>
</li>
<li>0 (successful call)
<p>The <strong>struct netent_data</strong>denoted by
<strong><em>netent_data_struct_addr</em></strong> is defined in
<strong>&lt;netdb.h&gt;</strong>.</p>
</li>
</ul>
<br>
<h3>Error Conditions</h3>
<p>When the <em>endnetent_r()</em> function fails, <em>errno</em> can be set
to:</p>
<dl>
<dt><em>[EINVAL]</em></dt>
<dd><p>The netent_data structure was not properly
initialized to hexadecimal zeros before initial use. For corrective action, see
the description for structure netent_data.</p></dd>
</dl>
<br>
<h3>Usage Notes</h3>
<ol>
<li>When the _XOPEN_SOURCE macro defined to the value 520 or greater, the network
file is always closed. When the _XOPEN_SOURCE macro is not so defined, the network file will
not be closed if a <em>setnetent_r()</em> call with a nonzero parameter value was previously
done.<br>
<br>
</li>
<li>The iSeries Navigator or the following CL commands can be
used to access the network database file:<br>
<br>
<ul>
<li>WRKNETTBLE (Work with Network Table Entries)</li>
<li>ADDNETTBLE (Add Network Table Entry)</li>
<li>RMVNETTBLE (Remove Network Table Entry)</li>
</ul>
<br>
</li>
<li>When you develop in C-based languages and an application is compiled with
the _XOPEN_SOURCE macro defined to the value 520 or greater, the <em>endnetent_r()</em>
API is mapped to<em>qso_endnetent_r98()</em>.<br>
<br>
</li>
</ol>
