i’ve done this program for two client —
inside this program i have to client which need two different action(operation) .the server accept the request of client by using pipe .to perform their desired operation the server again sent this data to process by using pipe.for both operation i have used single pipe for process1 and process2.after processing the sever request the process1 or process2 wrote the output in pipe which fetched by server.and sever use the respective pipe of client1 and client2 and write this output to client pipe which is then fetched by client.
to manage the sychronisation i’ve use sleep.we can also used signal for proper sync.
