[John x <xiachangqin66@xxxxxxxxxxx>]

the following is an example from README.heuristic

-------------------------------
void
proto_reg_handoff_PROTOABBREV(void)
{
    static int PROTOABBREV_inited = FALSE;
 
    if ( !PROTOABBREV_inited )
    {
        /* register as heuristic dissector for both TCP and UDP */
        heur_dissector_add("tcp", dissect_PROTOABBREV, proto_PROTOABBREV);
        heur_dissector_add("udp", dissect_PROTOABBREV, proto_PROTOABBREV);
    }
}

----------------------------------

Why cannot I use ip, like: heur_dissector_add("ip", dissect_PROTOABBREV, proto_PROTOABBREV);   ?


Thanks
John
