<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>

<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>

</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>
