I made a mistake in my last message. The third argument of the enum is obviously an int value (the same of the global_bit_order). You should use a define. So the enum is: #define LITTLE 0 #define BIG 1
Just a note that Wireshark already provides #defines for these. If you go this route please use "ENC_LITTLE_ENDIAN" and "ENC_BIG_ENDIAN" instead of adding your own.
const enum_val_t enum_gtp_market_data_feed[] = { { "Little Endian", "Decode as Little Endian", LITTLE }, { "Big Endian", "Decode as Big Endian", BIG}, { NULL, NULL, 0 } }; Regards Fabiano *Fabiano Ricci* ___________________________________________ Please consider the environment before printing this e-mail Il 24/07/2013 9.44, Fabiano Ricci ha scritto: Hi, You can let the user configure the filter by preferences. You can find many infos here: http://wiki.wireshark.org/Preferences and in the README.dissector file. EX: //creates and initialize a global var static gint global_bit_order = 0; //creates an enumeration with your options const enum_val_t enum_gtp_market_data_feed[] = { { "Little Endian", "Decode as Little Endian", "Decode as Little Endian" }, { "Big Endian", "Decode as Big Endian", "Decode as Big Endian" }, { NULL, NULL, 0 } }; //in the proto_register function //register the preference module module = prefs_register_protocol(proto, proto_reg_handoff); //Register enum prefs_register_enum_preference(module, "bit.order", "Decode as...", "Set the bit order", &global_itch_market, enum_itch_market_data_feed, TRUE); This will create an ITEM with your protocol name in the wireshark preference window. So the user can easily configure the bit order by change preferences in Edit->Preference->Protocols->YOUPROTO window. In your code you can check the var global_bit_order to understand if the user is filtering by BIG_END or LITTLE_END. Hope this help and is what you need.

But some time due to different architecture of server and client I get data in little endian format. I can write code for that as well, but I like that user can provide comment like if my capture file is little endian or big endian by any means. So based on user input I can easily select in which format dissector decode the protocol. Please help how to provide arugument or comment to customized dissector by user?
