Eagain Error


The select(2) call may be used to determine when it is possible to send more data. On the reconnection: the http-get tunnel is set ok, i mean, the socket connects and receives a "HTTP OK", so the program sends a RTSP "DESCRIBE" but the recv always return Macro: int ENOTTY Inappropriate I/O control operation, such as trying to set terminal modes on an ordinary file. I basically need a few more hours to wrap up the work I did so far.

You can use the select function to find out when the pending operation has completed; see Waiting for I/O. If you are sending UDP packets, then keep in mind that there is no guarantee of congestion control, and if you're sending packets over the Internet you will almost certainly get Macro: int ENETDOWN A socket operation failed because the network was down. Macro: int EPFNOSUPPORT The socket communications protocol family you requested is not supported. http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html

airandfingers commented Jan 21, 2014 Thanks for the instant response! In BSD and GNU, the number of open files is controlled by a resource limit that can usually be increased. I'm getting some of our C developers to take a look at this; we need to find some way around this issue by the end of the week. secondly i m not sure but probably check buff size like below if is already predefined Code: getconf -a |grep SOCK_MAXBUF and set and get send/rec buff size maybe try like

The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library. Is there any particular strategy to be followed 2) Is buffer size has exceeded its limits is the only reason ? 3) Can someone please give me a better idea/code, how See Limits on Resources, for details on the RLIMIT_NPROC limit. santigimeno added a commit to santigimeno/node-unix-dgram that referenced this issue May 29, 2014 santigimeno Eagain Error Linux

I'd be super happy if this were fixed and I could go back to unix-dgram-logging, however :) Collaborator santigimeno commented Jan 22, 2014 @airandfingers @briktop I ended up using the nextTick Macro: int EMFILE The current process has too many files open and can’t open any more.

Best regards. Its value is significant only when the return value of the call indicated an error (i.e., -1 from most system calls; -1 or NULL from most library functions); a function that One note: our fix doesn't discriminate between error types, so every message will always be retried.

Macro: int ENAMETOOLONG Filename too long (longer than PATH_MAX; see Limits for Files) or host name too long (in gethostname or sethostname; see Host Identification).

errno is defined by the ISO C standard to be a modifiable lvalue of type int, and must not be explicitly declared; errno may be a macro.

C Programming Error Codes Macro: int ETIMEDOUT A socket operation with a specified timeout received no response during the timeout period.

The nextTick solution avoids this but can really slow down the app with high traffic load airandfingers commented Jan 22, 2014 @santigimeno Losing data was something we were also worried about, Collaborator santigimeno commented Jan 22, 2014 @airandfingers You are right.
