<p>The <em>endservent_r()</em> function is used to close the service database
|
||
|
|
file. The file is opened by those functions that retrieve information about
|
||
|
|
services (for example, <em>getservent_r()</em>).</p>
|
||
|
|
|
||
|
|
<h3>Parameters</h3>
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt>struct servent_data *<strong><em>servent_data_struct_addr</em></strong>
|
||
|
|
(input) </dt>
|
||
|
|
|
||
|
|
<dd>Specifies the pointer to the servent_data structure, which is used to pass
|
||
|
|
and preserve results between function calls. The field serve_control_blk in the
|
||
|
|
servent_data structure must be initialized with hexadecimal zeros before its
|
||
|
|
initial use. If compatibility with other platforms is required, then the entire
|
||
|
|
servent_data structure must initialized with hexadecimal zeros before initial
|
||
|
|
use.</dd>
|
||
|
|
</dl>
|
||
|
|
|
||

<h3>Authorities</h3>
|
||
|
|
|
||
|
|
<p>No authorization is required.</p>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
<h3>Return Value</h3>
|
||
|
|
|
||
|
|
<p>The <em>endservent_r()</em> function returns an integer. Possible values
|
||
|
|
are:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>-1 (unsuccessful call)</li>
|
||
|
|
|
||
|
|
<li>0 (successful call)</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The <strong>struct servent_data</strong>denoted by
|
||
|
|
<strong><em>servent_data_struct_addr</em></strong> is defined in
|
||
|
|
<strong><netdb.h></strong>.</p>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
<h3>Error Conditions</h3>
|
||
|
|
<p>When the <em>endservent_r()</em> function fails, <em>errno</em> can be set
|
||
|
|
to:</p>
|
||
|
|
<dl>
|
||
|
|
|
||
|
|
<dt><em>[EINVAL]</em></dt>
|
||
|
|
<dd><p>The servent_data structure was not properly initialized with hexadecimal zeros before
|
||
|
|
initial use. For corrective action,see the description for structure servent_data.</p></dd>
|
||
|

|
||

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>When the _XOPEN_SOURCE
|
||
|
|
macro defined to the value 520 or greater, the services file is always closed.
|
||
|
|
When the _XOPEN_SOURCE macro is not so defined, the services file will not be closed if a
|
||
|
|
<em>setservent_r()</em> call with a non-zero parameter value was previously
|
||
|
|
done.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<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)</li>
|
||
|
|
|
||
|
|
<li>ADDSRVTBLE (Add Service Table Entry)</li>
|
||
|
|
|
||
|
|
<li>RMVSRVTBLE (Remove Service 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>endservent_r()</em> API is mapped to
|
||
|
|
<em>qso_endservent_r98()</em>.</li>
|
||
|
|
</ol>
|
||
|
|
|
