All,
 
Does anyone know the life cycle of "tvbuff_t *tvb" and " packet_info *pinfo"?
 
I'm working on reassembling a special protocol's (name it here XXX) PDU. Each Ethereal frame could include more than one XXX (header + PDU). The first fragment's sequence number is not equal to 0 and may be out of order. So I want to save the tvb and pinfo and use it later.
 
Thanks,
Chunfang
