Hi,

 

I have a dissector code (atmii) and I am having problem in understanding the following two lines of code:

 

In proto_register_atmii()

 

aal_dissector_table = register_dissector_table("atmii.aal2_payload", "AAL payload type", FT_UINT8, BASE_DEC);

 

and then in dissect_atmii()

 

if (!dissector_try_port(aal_dissector_table, payload_type, next_tvb, pinfo, tree)) {

proto_tree_add_item(atmii_tree,hf_atmii_aal2_payload, tvb, ATM_HEADER_LENGTH, -1, FALSE);

}

 

 

What does these two lines of code do in general as I’ve seen them in other protocols as well?

 

Thanks

Vishnu
