Hi, I had created Named Pipes(FIFO's) "Xid" in process A and that is shared to B thr STDIN( 0 ). Process A and B communicates thr named pipes"Xid" Process "A " writes on "Xid" and process "B" reads from "Xid". My probelm is Lets say if Process "A" is terminated, still Process B waits on named pipe"Xid". It blocks on read system call. How to over come this probelm. Help plz Thanks KSudheer. _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
