Thanks for your reply,
In my use case, the client requests are sequential and depend on each other.
which means when server receives a request from the client, it will decide what
to do based on previous requests received from that client. Also, each request
must have a reply and the client will send next request based on the reply
receives from the server.
Right now, I am using the example provided in the online guide.
(http://zguide.zeromq.org/pl:mtserver)
This example almost do what I want, but in the following line, it asks for a
round robin queue:
zmq_device (ZMQ_QUEUE, $clients, $workers);
Is there any way to implement my own queuing algorithm instead of ZMQ_QUEUE?
Thanks
Jerry

Subject: Re: [zeromq-dev] sending and receiving multiple messages and replies
from same thread
Two answers here. The first is, read the Guide or buy the ZeroMQ book
from O'Reilly, work through the examples, and you'll learn what you
need.
Second answer: what you are trying to do is probably wrong (and this
is very common for people who haven't yet digested how 0MQ works).
Creating one thread per client is a classic BSD socket pattern but not
common for 0MQ apps. You don't explain enough about your use-case to
know what the right direction is.
So I'd really suggest reading the Guide and building enough throw-away
examples to internalize the way it all works. Then, probably a ROUTER
for the server, a DEALER for the clients.
