Need to have non-blocking named pipes capable of two way communication in c on Linux

Question

Hi,

I want to create one server and one client(two separate programs) where in server creates two named pipes(i guess thats the minimum required for bidirectional flow of traffic) and then the client is started,and Client and server should be able to send and recieve data both ways all the time(full duplex types).I think that would require me to have non-blocking named pipes.Would like some help as i have been able to create half duplex type of communication but struggling to make a contineous seamless transfer of data between client and server happen.

Thanks
