<!----------- 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 <A href="xxfi_eom.html">xxfi_eom</A>.  smfi_replacebody may be called more than once.</TD>
</TR>
<TR align="left" valign=top>
<TH width="80">Effects</TH>
<TD>smfi_replacebody replaces the body of the current message.  If called 
more than once, subsequent calls result in data being appended to the new 
body.
</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>ctx</TD>
	<TD>Opaque context structure.
	</TD></TR>
    <TR valign="top"><TD>bodyp</TD>
	<TD>A pointer to the start of the new body data, which does not have to be null-terminated.  If bodyp is NULL, it is treated as having length == 0.  Body data should be in CR/LF form.
	</TD></TR>
    <TR valign="top"><TD>bodylen</TD>
	<TD>The number of data bytes pointed to by bodyp.
	</TD></TR>
    </TABLE>
</TD></TR>

<!----------- Return values ---------->
<TR>
<TH valign="top" align=left>RETURN VALUES</TH> 

<TD>smfi_replacebody fails and returns MI_FAILURE if:
<UL>
    <LI>bodyp == NULL and bodylen &gt; 0.
    <LI>Changing the body in the current connection state is invalid.
    <LI>A network error occurs.
    <LI>SMFIF_CHGBODY was not set when <A href="smfi_register.html">smfi_register</A> was called.
</UL>
Otherwise, it will return MI_SUCCESS.
</TD>
</TR>

<!----------- Notes ---------->
<TR align="left" valign=top>
<TH>NOTES</TH> 
<TD>
<UL>
    <LI>Since the message body may be very large, setting SMFIF_CHGBODY may significantly affect filter performance.
    <LI>If a filter sets SMFIF_CHGBODY but does not call smfi_replacebody, the original body remains unchanged.
    <LI>For smfi_replacebody, filter order is important.  <B>Later filters will see the new body contents created by earlier ones.</B>
</UL>
</TD>
