Because that's not the way it works :)
proto_reg_handoff_sctp()
Is called so the SCTP dissector can do its own registrations.
In void proto_register_sctp(void)
The SCTP dissector registers two dissector tables.
sctp_port_dissector_table = register_dissector_table("sctp.port", "SCTP port",
FT_UINT16, BASE_DEC);
sctp_ppi_dissector_table = register_dissector_table("sctp.ppi", "SCTP payload
protocol identifier", FT_UINT32, BASE_HEX);
Any dissector wanting to be called from the SCTP dissector needs to register in
those tables in its own handoff routine. In the menu bar there is an "internal"
menu
In that menu you can get a list of the dissector tables and what's been
registered in them.
Best regards
Anders
