How could side B know that side A has called "shutdown(socket, SHUT_RD)"? 1. no send is still valid, call / send() is no different still calls the function i do hope you are checking the return value from this 2. if you try to read it will return 0 to say its closed if it has not been done it will hang until either data is send or it has been closed if you use non-blocking it will return 0 if closed and EAGIAN if there is no data i think this is correct sombody correct me if i am wrong > I have a sample below, > 1. why the program doesn't exit with the singal SIGPIPE? > 2. why side A could do send while side B has call "shutdown(socket, > SHUT_RD)"? i am gueesing the send never gets called when the other side is closed - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
