int smfi_replacebody( SMFICTX *ctx, unsigned char *bodyp, int bodylen );
Replace message-body data.
|Called When||Called only from xxfi_eom. smfi_replacebody may be called more than once.|
|Effects||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.|
|ctx||Opaque context structure.|
|bodyp||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.|
|bodylen||The number of data bytes pointed to by bodyp.|
smfi_replacebody fails and returns MI_FAILURE if:
- bodyp == NULL and bodylen > 0.
- Changing the body in the current connection state is invalid.
- A network error occurs.
- SMFIF_CHGBODY was not set when smfi_register was called.
Otherwise, it will return MI_SUCCESS.
- Since the message body may be very large, setting SMFIF_CHGBODY may significantly affect filter performance.
- If a filter sets SMFIF_CHGBODY but does not call smfi_replacebody, the original body remains unchanged.
- For smfi_replacebody, filter order is important. Later filters will see the new body contents created by earlier ones.
