<h2>qtoq_close()--Close QoS Sockets Connection API</h2>
<div class="box" style="width: 80%;">
<br>
&nbsp;&nbsp;Syntax<br>
<pre>
#include &lt;qtoqsapi.h&gt;
int qtoq_close(
int socket_descriptor,
int *qos_descriptor,
unsigned int *qos_session,
)
</pre>
&nbsp;&nbsp;Service Program Name: QSYS/QTOQSAPI<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Default Public Authority: *EXCLUDE<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Threadsafe: Yes<br>
<!-- iddvc RMBR -->
<br>
</div>
<p><strong>qtoq_close()</strong> is called to close the socket and QoS session
that was created using the other qtoq_ sockets-type APIs. It performs a
standard sockets close(); on the socket descriptor, close the QoS session for
this connection and inform the QoS server that the connection should be closed
and the rule unloaded.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong><em>socket_descriptor</em></strong></dt>
<dd>(Input) Required
<p>The socket descriptor that was created to perform the TCP/IP communications
for this connection.</p>
</dd>
<dt><strong><em>qos_descriptor</em></strong></dt>
<dd>(Input) Optional
<p>Pointer to an integer for the value of the descriptor that the application
used to wait on QoS events.</p>
</dd>
<dt><strong><em>qos_session</em></strong></dt>
<dd>(Input) Required
<p>Pointer to an integer containing the QoS session ID that was returned when
the QoS connection was established.</p>
</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>None.</p>
<br>
<h3>Return Values</h3>
<table cellpadding="5">
<!-- cols="5 95" -->

<td align="left" valign="top"><em>0</em></td>
<td align="left" valign="top">if successful.</td>

<tr>
<td align="left" valign="top"><em>-1</em></td>
<td align="left" valign="top">if function failed. Errno indicates error
reason.</td>
</tr>
</table>
<br>
<h3>Error Conditions</h3>
<p>When this function call fails, the errno value is set to one of the
following:</p>
<dl>
<dt><em>[EBADF]</em></dt>
<dd><p>Descriptor not valid.</p>
</dd>
<dt><em>[EIO]</em></dt>
<dd><p>Input/output error.</p>
</dd>
<dt><em>[ENOBUFS]</em></dt>
<dd><p>There is not enough buffer space for the requested operation.</p>
</dd>
<dt><em>[EUNKNOWN]</em></dt>
<dd><p>Unknown system state.</p></dd>
</dl>

<h3>Error Messages</h3>

<h3>Usage Notes</h3>
<ol>
<li>The qtoq_close() API must be used in place of the normal close() sockets
call in an application using the QTOQ APIs. If it is not used, the results are
unpredictable.</li>
</ol>
