&nbsp;&nbsp;Syntax<br>
<pre>
#include &lt;netdb.h&gt;
void setservent(int <em>stay_open</em>)

<p>The <em>setservent()</em> function is used to prepare for sequential access
to the service database file. <em>setservent()</em> opens the file and
repositions the file marker to the beginning of the file.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>stay_open</strong></dt>
<dd>(Input) A value that indicates whether to leave the database file open
after each <em>getservbyname()</em> and <em>getservbyport()</em>. A nonzero
value results in the database file being left open.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>No authorization is required.</p>
<br>
<h3><a name="USAGE_NOTES">Usage Notes</a></h3>
<ol>
<li>The iSeries Navigator or the following CL commands can be
used to access the services database file:<br>
<br>
<ul>
<li>WRKSRVTBLE (Work with Service Table Entries)<br>
<br>
</li>
<li>ADDSRVTBLE (Add Service Table Entry)<br>
<br>
</li>
<li>RMVSRVTBLE (Remove Service Table Entry)</li>
</ul>
<br>
</li>
<li>Do not use the <em>setservent()</em> function in a multithreaded
environment. See the multithread alternative <em>setservent_r()</em>
function.<br><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>setservent()</em> API is mapped to
<em>qso_setservent98()</em>.</li>
