Hi,
Yeah, I do see my plugin in the tools->plugin list. But unfortunatly I do
not see my plugged-in protocol in edit->protocols list where the list of all
registered protocols and plugins like "pcli" are present.
I went thru a few plugin codes like pcli, gryphon etc.. they all use
dissector_add("PARENT_SUBFIELD", ID_VALUE, xxx_subiss_handle); where
PARENT_SUBFIELD is usually "udp.port" or "tcp.port", ID_VALUE = i guess the
port # and then the handle..
in "void proto_reg_handoff_xxx_subiss(void) "
I did not get the use of this function.. what is it supposed to do and why
taking into account tcp, udp ports?
I have attached the code with this. Also I guess there is some problem in
the
"void proto_register_xxx_subiss(void)" routine. I'm never able to call:
static void dissect_xxx_subiss(tvbuff_t *tvb, packet_info *pinfo,
proto_tree *tree)
Any help, wut I'm doing wrong? I do not have preference menus. That's why I
did not register any prefrences. Anyway the basic problem is protocol
registration itself.
Thanks and Regards,
-Parul
