Hi,
I have looked into those examples. Well, the
TCP_COMBINED_SERVER runs different processes(on
different ports by creating threads).
In my application, I have to split an association
among several processes. Each process should be able
to send on different streams of the same association.
In the examples(TCP_COMBINED_SERVER), each thread
handles an association.so might have understood the
problem.
lets take an example. The client wants to have 4
files and sends a request to the server. Association
is set up. Now tthe server should spawn threads, such
that ON THE SAME ASSOCIATION, ALL THE THREADS NEED TO
SEND INFORMATION(here each file) ofcourse on DIFFERENT
STREAMS. So while spawning the threads, I see that the
threads were not able to send, so prob. that we need
to send association details, I am sending the
association ID and all others, still its not working.
Please let me know how to do this. Or else how do you
do MULTISTREAMING for the above said application.
Hope I explained the prob well. Waiting for the
solution. THanks.
