Hi,
You could export the relevant ASN1 sequence by adding somethig like this from
GSM_MAP in the gsm_map.cnf file
#.EXPORTS
AddressString
Add packet-ranap.h to the includes in your file and then use the exported funktion
offset = dissect_gsm_map_AddressString();
in your dissector. Is this something you plan to offer for inclusion in Wireshark?
Best regards
Anders

Subject: [Wireshark-dev] Including ASN.1 format coding in a C dissector
Hi ,
I have written a dissector for a protocol which has a coding standard of Tag-Length-Value. Now in this dissector , I have to add some messages of RANAP protocol which has a coding standard in ASN.1 format.Already the dissector for RANAP is available in the wireshark. Now:
1.Can I call the existing dissector for those particular messages??? If so how do I do that??
2. If I want to include it normally in my dissector, how can I convert the ASN.1 format to obtain the tag and lengths of individual parameters??
Can anybody please help??
