(Normally, this does not occur in Linux.

Linux Errno Example

The file was the wrong type for the operation, or a data file had the wrong format. EXAMPLE top An example of the use of socket() is shown in getaddrinfo(3). If the value of errno should be preserved across a library call, it must be saved: if (somecall() == -1) { int errsv = errno; printf("somecall() failed\n"); if (errsv == ...) How to explain the use of high-tech bows instead of guns In a World Where Gods Exist Why Wouldn't Every Nation Be Theocratic?

  • Macro: int EWOULDBLOCK In the GNU C Library, this is another name for EAGAIN (above).
  • 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.
  • Valid error numbers are all nonzero; errno is never set to zero by any system call or library function.

  • The MSG_CONFIRM flag is a Linux extension.
  • Use packet(7) instead.
  • The protocol number to use is specific to the ‚Äúcommunication domain‚ÄĚ in which communication is to take place; see protocols(5).

  • You can choose to have functions resume after a signal that is handled, rather than failing with EINTR; see Interrupted Primitives.

If you'd like to contribute content, let us know. For a connectionless socket (for datagram protocols, such as UDP), you get EDESTADDRREQ instead. EOPNOTSUPP Some bit in the flags argument is inappropriate for the socket type. Errno 0 Macro: int EPROTOTYPE The socket type does not support the requested communications protocol.

SOCK_RDM Provides a reliable datagram layer that does not guarantee ordering. Macro: int ENOENT No such file or directory.

The functions setsockopt(2) and getsockopt(2) are used to set and get options, respectively. Ebadf Macro: int EINTR Interrupted function call; an asynchronous signal occurred and prevented completion of the call. You can convert an errno value to a useful string with the strerror function. These options are defined in .

Errno.h In C

On error, -1 is returned, and errno is set appropriately. ENOBUFS No buffer space available (POSIX.1 (XSI STREAMS option)) ENODATA No message is available on the STREAM head read queue (POSIX.1) ENODEV No such device (POSIX.1) ENOENT No such file or Linux Errno Example Some socket types may not be implemented by all protocol families. Posix Error Codes Macro: int ENXIO No such device or address.

For sendmsg(), the message is pointed to by the elements of the array msg.msg_iov. http://dualathlonserver.com/error-codes/socket-error-codes-unix.php Macro: int EBUSY Resource busy; a system resource that can’t be shared is already in use.

You have to detect the failure and handle the error. How To Use Errno Out-of-band data may also be transmitted as described in send(2) and received as described in recv(2). This error can happen in a few different situations: An operation that would block was attempted on an object that has non-blocking mode selected.

If a piece of data for which the peer protocol has buffer space cannot be successfully transmitted within a reasonable length of time, then the connection is considered to be dead.

Macro: int EDESTADDRREQ No default destination address was set for the socket. Macro: int ERANGE Range error; used by mathematical functions when the result value is not representable because of overflow or underflow. Macro: int ENOTEMPTY Directory not empty, where an empty directory was expected. Errno To String Terms Privacy Security Status Help You can't perform that action at this time.

Note that any number of linked channels count as just one file opening; see Linked Channels. Macro: int EIO Input/output error; usually used for physical read or write errors. Typically, this error occurs when you are trying to delete a directory. http://dualathlonserver.com/error-codes/solaris-socket-error-codes.php Thanks!

This condition is detected by the exec functions; see Executing a File. EACCES (For UNIX domain sockets, which are identified by pathname) Write permission is denied on the destination socket file, or search permission is denied for one of the directories the path You have to include errno.h header file to use external variable errno. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

On GNU/Hurd systems, this error can happen for many calls when the object does not support the particular operation; it is a generic indication that the server knows nothing to do 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 Macro: int EROFS An attempt was made to modify something on a read-only file system. Macro: int EILSEQ While decoding a multibyte character the function came along an invalid or an incomplete sequence of bytes or the given wide character is invalid.

EAFNOSUPPORT The implementation does not support the specified address family. Macro: int ECONNABORTED A network connection was aborted locally. ENOEXEC Exec format error (POSIX.1) ENOKEY Required key not available ENOLCK No locks available (POSIX.1) ENOLINK Link has been severed (POSIX.1) ENOMEDIUM No medium found ENOMEM Not enough space (POSIX.1) ENOMSG A description of the project, information about reporting bugs, and the latest version of this page, can be found at https://www.kernel.org/doc/man-pages/.

This operation may also be used to set the process or process group that receives the I/O and asynchronous notification of I/O events via SIGIO. This error never occurs on GNU/Hurd systems. I have been writing the client server code, but still I am unable to communicate. Locally detected errors are indicated by a return value of -1.

Note that registered members see fewer ads, and ContentLink is completely disabled once you log in. What is Epsilon Convergence in Probability? Datagrams are generally received with recvfrom(2), which returns the next datagram along with the address of its sender.
