|
|
|
|
<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>

|
<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>
