When you call aio_cancel, the normal result is for the operations affected to complete with this error; see Cancel AIO Operations. Users do not usually see this error because functions such as read and write translate it into a SIGTTIN or SIGTTOU signal. Macro: int ENEEDAUTH ??? EAFNOSUPPORT Address family not supported by protocol family EDESTADDRREQ Destination address required EMSGSIZE Message too long ENOTSOCK Socket operation on non-socket EOPNOTSUPP Operation not supported on socket http://dualathlonserver.com/error-codes/socket-programming-error-codes.php

Macro: int EDOM Domain error; used by mathematical functions when an argument value does not fall into the domain over which the function is defined. Powered by Atlassian | Scroll Viewport Skip to content Ignore Learn more Please note that GitHub no longer supports old versions of Firefox. Macro: int ENFILE There are too many distinct file openings in the entire system. It is probably a good idea to delay for a few seconds before trying it again, to allow time for other processes to release scarce resources.

Linux Socket Error Codes

Reload to refresh your session. When the network signals an error condition to the protocol module (e.g., using a ICMP message for IP) the pending error flag is set for the socket. Some socket functions don’t make sense for all types of sockets, and others may not be implemented for all communications protocols.

  • On GNU/Hurd systems, this error never happens; you get a signal instead.
  • Portability Note: In many older Unix systems, this condition was indicated by EWOULDBLOCK, which was a distinct error code different from EAGAIN.
  • Use Escape to close the list and return to the search input.
  • EINVAL Invalid flags in type.

Thanks! Some functions that must always block (such as connect; see Connecting) never return EAGAIN. Repairing this condition usually requires unmounting, possibly repairing and remounting the file system. Linux Errno To String How do i access this "errno" though?

These options are defined in . Posix Error Codes Macro: int EROFS An attempt was made to modify something on a read-only file system. SOCK_SEQPACKET Provides a sequenced, reliable, two-way connection- based data transmission path for datagrams of fixed maximum length; a consumer is required to read an entire packet with each input system call. https://gist.github.com/gabrielfalcao/4216897 Macro: int EMSGSIZE The size of a message sent on a socket was larger than the supported maximum size.

See Socket Options. Enxio When you get this error, you can be sure that this particular function will always fail with ENOSYS unless you install a new version of the C library or the operating There are some very serious drawbacks. A stream socket must be in a connected state before any data may be sent or received on it.

Macro: int EBADF Bad file descriptor; for example, I/O on a descriptor that has been closed or reading from a descriptor open only for writing (or vice versa). http://stackoverflow.com/questions/27096985/getting-error-code-when-creating-a-socket-in-linux They do not preserve record boundaries. Linux Socket Error Codes You can choose to have functions resume after a signal that is handled, rather than failing with EINTR; see Interrupted Primitives. Linux Errno Example Macro: int EISCONN You tried to connect a socket that is already connected.

Putting the socket call and the test for < 0 in one statement, the above code could look like this, and you'll be a real UNIX pro: #include #include http://dualathlonserver.com/error-codes/solaris-socket-error-codes.php This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files). Trying the same operation again will block until some external condition makes it possible to read, write, or connect (whatever the operation). This is my code so far: int connectSocket = 0; connectSocket = socket(AF_INET, SOCK_STREAM, 0); printf("%d\n", connectSocket); if (connectSocket == -1){ printf("socket failed with error: %s\n", error_string); //TODO: HELP DECLARING error_string Enotsup

The next operation on this socket will return the error code of the pending error. Error occurred Language Loading... The AF_ALG protocol type was added in Linux 2.6.38. http://dualathlonserver.com/error-codes/socket-error-codes-in-linux.php Macro: int ESTALE Stale file handle.

Macro: int ENOTBLK A file that isn’t a block special file was given in a situation that requires one.

Macro: int EDIED On GNU/Hurd systems, opening a file returns this error when the file is translated by a program and the translator program dies while starting up, before it has EAFNOSUPPORT The implementation does not support the specified address family. noname007 commented Sep 13, 2016 👍 Sign up for free to join this conversation on GitHub. Einval Errno This error never occurs on GNU/Hurd systems.

Abstract definition of convex set Simplificate an array DDoS: Why not block originating IP addresses? Macro: int ENOSPC No space left on device; write operation on a file failed because the disk is full. It indicates that the shortage is expected to pass, so your program can try the call again later and it may succeed. http://dualathlonserver.com/error-codes/socket-error-codes-linux.php Macro: int EHOSTDOWN The remote host for a requested network connection is down.

Macro: int EEXIST File exists; an existing file was specified in a context where it only makes sense to specify a new file. yahya c linux sockets share|improve this question asked Nov 24 '14 at 2:23 Yahya Uddin 2,04811441 2 See errno(3) and strerror(3) manual pages. –Nikolai N Fetissov Nov 24 '14 at The operation of sockets is controlled by socket level options. This error happens on operations that are supposed to manipulate child processes, when there aren’t any processes to manipulate.

Once connected, data may be transferred using read(2) and write(2) calls or some variant of the send(2) and recv(2) calls.

Some of these error codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library. This often indicates a cycle of symbolic links. I hope this would help.

Also, the BSD socket errors are defined to very different values than are used in UNIX, BSD, and Linux programs. Reload to refresh your session.

Application developers are very strongly encouraged to use the WSA error constants in socket applications. This is a “file doesn’t exist” error for ordinary files that are referenced in contexts where they are expected to already exist.
