Wireshark · Wireshark-dev: Re: [Wireshark-dev] Adding dynamic fields to tree from dissector

You may want to look at the diameter dissector (register_diameter_fields).  It registers a lot of its fields when Wireshark sees a diameter packet for the first time.

I have tried to implement this and found out that all dissectors
register their fields in a first routine that is called by wireshark:
proto_register_*.
But I can get info about protocol fields and types only after user
chooses file with protocol description via dissector setting. It means
that I can get that info only in
proto_reg_handoff_*.

Is there a way to register fields in a proto_reg_handoff_*, not in a
proto_register_*?
