<th width="80">Purpose</th>
<td>The <tt>DMARC_POLICY_T</tt> is an opaque structure used to communicate on a per message
basis with the library. It is to enter information into policy and to receive information
from policy.

<th width="80">Synopsis</th>
<td>
<blockquote>
#include <dmarc.h>
<p>
DMARC_POLICY_T *pctx;
</blockquote>
</td>

<th width="80">DMARC_POLICY_T</th>
<td>
This opaque data type must be initialized using <a href="opendmarc_policy_connect_init.html">opendmarc_policy_connect_init()</a> and later freed using <a href="opendmarc_policy_connect_shutdown.html">opendmarc_policy_connect_shutdown()</a>.
<p>
In generally you may initialize it when the connection is first accepted and keep it active until the remote client disconnects. If there are multiple envelopes per envelope, you may call <a href="opendmarc_policy_connect_rset.html">opendmarc_policy_connect_rset()</a> to reset the opaque structure for re-use with the next message.
</td>
</tr>
<tr align="left" valign=top>
<th width="80">Usage</th>
<td>
Each connection from a client to your SMTP server will require its own <tt>DMARC_POLICY_T</tt> pointer. Be certain to free this structure by calling <a href="opendmarc_policy_connect_shutdown.html"></a> when the connection is discontinued to avoid a memory leak.
</td>
</tr>
<tr>
<th valign="top" align=left>NOTES</th>
<td>
<ul>
<li><tt>DMARC_POLICY_T</tt> is thread safe provided it is not used concurrently by two or more threads. There should be a minimum of one DMARC_POLICY_T pointer per thread.
</ul>
