What you said is right, in this case, if I understood well,
TCP is not used for streams but only for control messages...
Some suggestion about the dissection?

Thank you Jaap!

you MUST use a hf_ field as the second parameter.
you can NOT use NULL since
1, NULL is not an integer and is therefore the WRONG type for the
second parameter and would anyway give you a compiler error if you
tried.
2, there are plenty of examples on how to use hf_fields in the code.
