<h2>mkDPIunregister()--Make a DPI Unregister Packet</h2>
<div class="box" style="width: 50%;">
<br>
&nbsp;&nbsp;Syntax<br>
<pre>
#include &lt;qtossapi.h&gt;
unsigned char *mkDPIunregister(
char <em>reason_code</em>,
char <em>*group_p</em>);
</pre>
<br>
&nbsp;&nbsp;Service Program Name: QTOSSAPI<br>

<p>The <strong>mkDPIunregister()</strong> function makes a DPI unregister
packet and returns a pointer to the packet.</p>
<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->
<!-- Instead, use the commented out coding below to indicate NONE. -->
<h3>Authorities and Locks</h3>
<!-- Use this if there are no authorities and locks. -->
<p>None.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>reason_code</strong></dt>
<dd>(Input) The reason for the unregister operation. See the
<strong>&lt;qtossapi.h&gt;</strong> file for a list of defined reason
codes.<br>
<br>
</dd>
<dt><strong>group_p</strong></dt>
<dd>(Input) A pointer to a NULL-terminated character string that represents the
subtree to be unregistered. The subtree must have a trailing dot.</dd>
</dl>
<br>
<h3>Return Value</h3>
<table cellpadding="5">
<!-- cols="15 85" -->
<tr>
<td align="left" valign="top"><em>pointer value</em></td>
<td align="left" valign="top">The <strong>mkDPIunregister()</strong> function
was successful. The value returned is a pointer to the DPI packet.
<p>If successful, then a pointer to a static DPI packet buffer is returned. The
first 2 bytes of the buffer (in network byte order) contain the length of the
remaining packet. The <strong>DPI_PACKET_LEN()</strong> function can be used to
calculate the total length of the DPI packet.</p>
</td>
</tr>
<tr>
<td align="left" valign="top"><em>NULL</em></td>
<td align="left" valign="top">The <strong>mkDPIunregister()</strong> function
was not successful.
<p>If unsuccessful, then a NULL pointer is returned.</p>
</td>
</tr>
</table>
<p>Be aware that the static buffer for the DPI packet is shared by other
mkDPI<em>xxxx</em>() functions that create a serialized DPI packet.</p>
<p>For more information, see &quot;SNMP Subagent Problem Determination&quot; in the <a
href="../books/sc415412.pdf" target="_blank">Simple Network Management
Protocol</a> <img src="wbpdf.gif" alt="Link to PDF"> book.</p>
<h3>Usage Notes</h3>
<p>The <strong>mkDPIunregister()</strong> function creates a serialized DPI
UNREGISTER packet that can then be sent to the SNMP agent. Normally, the SNMP
peer then sends a DPI RESPONSE packet back, which details if the unregister was
successful or not.</p>
