[Wireshark-dev] Dissection of LTE-RRC

Hi All,

I have been trying to make RRC Dissector using the source code available at
http://anonsvn.wireshark.org/viewvc/trunk-1.4/epan/dissectors/.

Simply, I am trying to build a library in any directory. After that, I copy
the library to the plugin directory of wireshark. When I run wireshark and
send some packets, I get DL CCCH message only, proto_register_protocol
invokes only "dissect_lte_rrc_DL_CCCH_Message" Function. I made a simple
change to meet my motive. Instead, I invoked "dissect_lte_rrc_Message",
which further calls dissector function for DL CCCH, UL CCCH, UL DCCH etc.
But, now i have to make a decision based on which only one of all is called.
Presently, when all the three dissector function is invoked.

Please, suggest me a suitable method to this. Can i select based on message
type to differentiate UL CCCH, UL DCCH, DL CCCH messages? Or, is there any
other method to differentiate the messages?

Regards,
Vishal
