UDP protocol. I am using the following code to set a timeout on a socket in which I'm waiting for an acknowledgement. I am not sure why I am getting errno 11, resource temporarily unavailable. //set timer for recv_socket struct timeval tv; tv.tv_usec = TIMEOUT_MS; if(setsockopt(rcv_sock, SOL_SOCKET, SO_RCVTIMEO,&tv,sizeof(tv)) < 0){ printf("Error setting the socket timeout.\n"); } int recv_msg_len; if(recv_msg_len = recvfrom(rcv_sock, ackBuffer,sizeof(ackBuffer), 0, (struct sockaddr *) &servAddr2, &fromSize) < 0){ //timeout reached printf("Error Reporting: %d : errno 11 resource temporarily unavailable python %s\n", errno, strerror(errno)); num_timeouts++; } I have also tried the select method that was mentioned in the comments. I have the following code inside a loop, but the recvfrom never times out. fd_set set; FD_ZERO(&set); /* empties the set */ FD_CLR(rcv_sock,&set); /* removes FD from the set */ FD_SET(rcv_sock,&set); /* adds FD to the set */ if(select(rcv_sock + 1, &set, NULL, NULL, &tv) < 0){ printf("\nError Reporting: %d : %s\n\n", errno, strerror(errno)); return -1; } if(!FD_ISSET(rcv_sock,&set)){ /* true if FD is in the set */ printf("socket is not set properly.\n"); } c sockets udp share|improve this question edited Nov 25 '12 at 21:58 asked Nov 25 '12 at 19:37 rharrison33 5382927 Try using the select() and non-blocking sockets instead. The select() approach is much more flexible, reliable and portable. –Michael Sh Nov 25 '12 at 21:51 There is no call to recvfrom() int he second snippet. –alk Nov 26 '12 at 11:09 add a comment| 2 Answers 2 active oldest votes up vote 9 down vote accepted When calling recvfrom() on a blocking socket and a time out had been set using setsockopt() it is normal to get the error EAGAIN (11) in case the call to recvfrom() times out (that is: no data was received in the time period specified as time out). Verbatim from man recvfrom: RETURN
