<pre>
#include <libmilter/mfapi.h>
int smfi_opensocket(

</pre>
Attempt to create the interface socket MTAs will use to connect to the
filter.
</td></tr>
<!----------- Description ---------->
<tr><th valign="top" align=left>DESCRIPTION</th><td>
<table border="1" cellspacing=1 cellpadding=4>
<tr align="left" valign=top>
<th width="80">Called When</th>
<td>Called only from program mainline, before calling
<tt>smfi_main()</tt>.</td>
</tr>
<tr align="left" valign=top>
<th width="80">Effects</th>
<td>smfi_opensocket attempts to create the socket specified previously by
a call to <tt>smfi_setconn()</tt> which will be the interface between MTAs
and the filter. This allows the calling application to ensure that the
socket can be created. If this is not called, <tt>smfi_main()</tt> will
do so implicitly. </td>
</tr>
</table>
<!----------- Arguments ---------->
<tr><th valign="top" align=left>ARGUMENTS</th><td>
<table border="1" cellspacing=0>
<tr bgcolor="#dddddd"><th>Argument</th><th>Description</th></tr>
<tr valign="top"><td>rmsocket</td>
<td>A flag indicating whether or not the library should try to
remove any existing UNIX domain socket before trying to create
a new one.
</td></tr>

</td></tr>
<!----------- Return values ---------->
<tr>
<th valign="top" align=left>RETURN VALUES</th>
<td>smfi_opensocket will fail and return MI_FAILURE if:
<ul>
<li>The interface socket could not be created for any reason.
<li><tt>rmsocket</tt> was <tt>true</tt>, and either the socket could
not be examined, or exists and could not be removed.
<li><tt>smfi_setconn()</tt> has not been called.
</ul>
Otherwise, it will return MI_SUCCESS
