<TR><TH valign="top" align=left width=100>SYNOPSIS</TH><TD>
<PRE>
#include &lt;libmilter/mfapi.h&gt;
int smfi_opensocket(
bool rmsocket
);
</PRE>
Attempt to create the interface socket MTAs will use to connect to the
filter.

<!----------- 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,
after calling <TT>smfi_setconn()</TT> and <TT>smfi_register()</TT>,
but 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 create the socket implicitly
(without removing a potentially existing UNIX domain socket).
</TD>
</TR>

<!----------- 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>
</TABLE>
</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> or <TT>smfi_register()</TT>
have not been called.
</UL>
Otherwise, it will return MI_SUCCESS
