zeromq - ZMQ: How to implement a two-way inter-process communication? -

i trying implement inter-process communication.

the model: part a -> sends messages part b.

i have implemented using client-server example zmq tutorial (code attached bellow), facing issues process "locked".

what best practice implement kind of model?

it not classic "client-server". 1 part sends data second part, , second part uses it.

is there option send message timeout, not lock process?

any input / example appreciated!

server:

zmq::context_t context(1); zmq::socket_t socket(context, zmq_rep); socket.bind("tcp://*:5555"); .. socket.recv(&request);                              // server.receives first socket.send(reply);                                 // server.sends next client ..                                                  //       .analyze .recv'd data 

client:

requester = context.socket(zmq.req); requester.connect("tcp://localhost:5555"); requester.send(str.getbytes(), 0);                 // client.sends byte[] reply = requester.recv(0);                  // client.receives
