[erlang-questions] {packet, PacketType} for little-signed packets

[Torben Hoffmann]

Hi Pablo,

I don't quite understand what your issue is, but it might be due to my lack
of understanding of the gen_tcp details. If not I think you should rephrase
your question.

Anyway, I have a piece of advice based on your code sniplet.

If you are defining the protocol yourself I would strongly suggest that you
make Length equal to the size of the Message since it makes decoding a lot
easier. I have dealt with Q.SIG and there the length in the PDU also depends
on the size of the header which forces one to do the decoding in two steps
instead of having the option to do it in one step in the function clause
pattern match.

Cheers,
Torben
