<pre>
#include <libmilter/mfapi.h>
int smfi_replacebody(
SMFICTX *ctx,
unsigned char *bodyp,

<!----------- 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 > 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>
