seeking networking and pthreads advice

seeking networking and pthreads advice

[Christian Schaefer]

hi there,

I want to write a networking module which communicates with specially
prepared messages over tcp/ip sockets.
thats no problem.
those messages belong to different dialogs. meaning: every dialog is a
sequence of client and server messages.
but since there can be several dialogs active, I had following idea:

I want to have a queue of pthreads. one for each open dialog. and a
message-engine, that gives the identifier of the current message to each
thread until one answers "that message is mine".

I would know how to do this, but since the message handling requires a
lot of data from the application I wondered how to give the thread
access to that data.

what I did is this:
I build a rather complicated struct with all general data in it.
and as a argument to the pthread I gave a pointer to that struct.
is this ok, or should i use global variables or is there a much better
way that I can not think of right now?

thanks in advance

This doesn't sound like gcc question. This is a design question, or a
    threads question. I suggest you try a more appropriate forum -
    comp.programming.threads, for example.

you're probably right. but I am not a news/forum reader and strongly
prefere mailing lists. maybe you have an advice for a good programming
ml since I couldn't find a good one since month..
