The socket is setup as AF_UNIX, SOCK_STREAM. It works most of the time, but occasionally resource temporarily unavailable socket read gets this error. The receiving end of the socket appears to be working properly. I know this isn't very detailed, but I'm just looking for general ideas. Thanks! c linux sockets unix share|improve this question edited Jan 17 '13 at 9:40 Ashwini Chaudhary 132k20199276 asked Jan 17 '13 at 0:49 giroy 73841634 Is this related? stackoverflow.com/questions/5737493/… –paddy Jan 17 '13 at 0:52 2 Are you setting your socket to O_NONBLOCK ? –Deepankar Bajpeyi Jan 17 '13 at 0:57 I don't think it is related to that post. My sockets are SOCK_STREAM which I believe are blocking which is what I want. –giroy Jan 17 '13 at 0:59 2 Whether a stream is blocking or non-blocking is independent of whether it's SOCK_STREAM or SOCK_DGRAM. The answer there is relevant. –Barmar Jan 17 '13 at 1:33 add a comment| 2 Answers 2 active oldest votes up vote 35 down vote accepted "Resource temporarily unavailable" is the error message corresponding to EAGAIN, which means that the operation would

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) http://stackoverflow.com/questions/13554691/c-sockets-errno-11-resource-temporarily-unavailable < 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. –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
by marcgron » Mon May 06, 2013 5:44 pm I tried to find a solution, but haven't. I have tried many approaches but none has worked fine.I have an arduino connected https://www.raspberrypi.org/forums/viewtopic.php?t=42931&p=346024 to a usb port of the raspberry. The messages I get from the serial port are ASCII and follow a given structure. They always start with a large letter (A-Z) and end with ";\n" .I http://code.activestate.com/lists/python-list/163853/ made a Python script on my desktop computer, and it worked fine. On the RPi however it dies after a few seconds returning:Code: Select allTraceback (most recent call last):
File "./code.py", line 114, in resource temporarily
serdata = ser.readline()
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 449, in read
buf = os.read(self.fd, size-len(read))
OSError: [Errno 11] Resource temporarily unavailableThe error message above was produced by the following (here very simplified) code:Code: Select allser = serial.Serial('/dev/ttyUSB0', 9600)
While 1:
serdata = ser.readline()
serdata = os.linesep.join([s for s in serdata.splitlines() if s])
and from there I use the serdata to my purposes. However, it resource temporarily unavailable won't work on the RPi.I tried alot of other codes, one was from: http://blog.hekkers.net/2013/04/09/rasp ... nd-python/I modified the function p1parse a little but the code didn't work. It runs for some seconds and returns"Error reading port".Any ideas? What is the proper way of reading the serial port in Python?My data is very simple and always follow a structure, as mentioned in the beginning. The only thing that varies is the length of the data received. Posts: 9Joined: Tue Mar 05, 2013 1:24 pm by jerdavis » Tue May 07, 2013 7:51 pm Are you sure you're getting the correct port? My USB serial device comes up at /dev/ttyACM0 on the Pi. You might want to try connecting with a terminal app and test that way. Posts: 1Joined: Tue May 07, 2013 7:49 pm by marcgron » Wed May 08, 2013 7:04 pm Thanks for your reply!I am quite sure. I double checked it, and it is correct. I checked it from dmesg.I tried running a serial console to monitor the serial port. I didn't use \r\n, just \n. So next lines start kind of in the middle. I'll try to change that and see how it affects it. I hope that is the problem, because my script works
