In such cases, a successful return can be distinguished from an error return by setting errno to zero before the call, and then, if the call returns a status that indicates Of the following list, symbols that are not used on the current platform are not defined by the module.

If the entire function is not available at all in the implementation, it returns ENOSYS instead. I can send a pull request if that's the case. I agree you should be checking the error code hillar pushed a commit to hillar/pigsty that referenced this issue Feb 9, 2014 HillarIf you get this error, you might want to increase the RLIMIT_NOFILE limit or make it unlimited; see Limits on Resources.
It allows to have some kind of congestion control via the `congestion` and `writable` events. - This patch adds the `unix-connect` protocol that uses this functionality. Posix Error Codes Once in writable mode it flushes the queue and keeps sending messages as normal. - It avoids problems like the ones described in https://github.com/bnoordhuis/node-unix-dgram/issues/4.">src: add 'unix-connect' protocol … - Starting with The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.

Macro: int ENOMEM No memory available. This indicates an internal confusion in the file system which is due to file system rearrangements on the server host for NFS file systems or corruption in other file systems. This might be a realistic solution for the timeframe of within the week :) It probably requires configuration of the syslog daemon. Reload to refresh your session. Npm Error Getaddrinfo Eagain

Linux Errno Example Macro: int ESTALE Stale file handle. Since you get -1 on recv it means there was some sort of error (or timeout!) you then need to check errno variable. –Matt Feb 5 '11 at 3:18 add a

Here is the code: Expand|Select|Wrap|Line Numbers //LISTENING... A function returns this error when certain parameter values are valid, but the functionality they request is not available. When this happens, you should try the call again. 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

This isn't solving my problems though, because the error is happening on every try. It depends on the rest of the code what the best/cleanest solution is. This thread has a simple example of using select() to deal with EAGAIN, and is followed by significant discussion about what sorts of surprises lurk beneath the surface. Macro: int ENOENT No such file or directory.
Macro: int ENFILE There are too many distinct file openings in the entire system. Macro: int EACCES Permission denied; the file permissions do not allow the attempted operation. They are not yet documented. I could be wrong (I haven't tested this hypothesis), but I don't think we're losing data.
In general when using non-blocking sockets you already have a more or less central select/poll/epoll/kqueue call where all the socket multiplexing is done, including EAGAIN handling.
