text of the error: PHP Warning: socket_recv(): unable to read from socket [11]: Resource temporarily unavailable in /home/luca/Documenti/Tesi/M3 Agent Page/lib/KPICore.php on line 236 (line 236 is the line with the socket_recv call) php sockets share|improve this question asked Jul 23 '12 at 10:13 Katuiros 31110 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted The error is EAGAIN (or EWOULDBLOCK, sometimes those are the same error) and means that the socket is non-blocking and that there is nothing to read at the moment. You can busy-wait while you have that error until you read something, or you use some other method to find out if there is data to read before trying to receive. share|improve this answer answered Jul 23 '12 at 10:20 Some programmer dude 212k16146255 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and term

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 http://stackoverflow.com/questions/13554691/c-sockets-errno-11-resource-temporarily-unavailable 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 : %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. –a

Additionally, one or more flags can be specified to modify the behaviour of the function. buf is passed by reference, so it must be specified as a variable in the argument list. Data read from socket by socket_recv() will be returned in buf. Parameters socket The socket must be a socket resource previously created by socket_create(). buf The data received will be fetched to the variable specified with buf. If an error occurs, if the c
