Wireshark · Wireshark-dev: Re: [Wireshark-dev] Query on proto_reg_handoff_<>

["Maynard, Chris" <Christopher.Maynard@xxxxxxxxx>]

You want new_create_dissector_handle().  find_dissector() is used to obtain a handle for an already registered dissector.

 

Take a look at the example given in section 1.2 of doc/README.developer and packet-cmp.c’s handoff function as another example.

Hi All,

 

 

I am new to wireshark development and having some doubt regarding my new dissector development:

 

In my “proto_register_bsapb64()” I have done the

{

 

   proto_bsapb64 = proto_register_protocol("ANSI BSMAP B64 Coding",

                                      "BSMAP BASE64", "bsapb64");

 

And

 

new_register_dissector("bsapb64", dissect_bsapb64, proto_bsapb64);

}

 

And In “proto_reg_handoff_bsapb64()” function I want to do :

{

 

dissector_handle_t bsapb64_handle;

 

<????????>

 

dissector_add_string("media_type", "application/FemtoInterfaceMsg", bsapb64_handle);

}

 

So my doubt is to get the bsapb64_handle whether I should be doing “new_create_dissector_handle(dissect_bsapb64, proto_bsapb64)” or “find_dissector(“bsapb64”)”

I am really confused over there uses.

 

 

Any help would really be appreciated. Thanks.

 

Regards,

Varun
