ERRORS top These are some standard errors generated by the socket layer. Macro: int EGREGIOUS You did what? http://globalinfoindex.com/error-code/linux-error-code-22.php

Find lane lines Save output of Con statement to different folder Why doesn't my (battery-powered) light work in the cold? The system cannot allocate more virtual memory because its capacity is full. Users do not usually see this error because functions such as read and write translate it into a SIGTTIN or SIGTTOU signal. SEE ALSO top errno(1), err(3), error(3), perror(3), strerror(3) COLOPHON top This page is part of release 4.08 of the Linux man-pages project. http://stackoverflow.com/questions/27096985/getting-error-code-when-creating-a-socket-in-linux

Linux Errno Example

This is used by the file locking facilities; see File Locks. Is Configuration Management useable for a small number of servers? MSG_ERRQUEUE indicates that no data was received but an extended error from the socket error queue. An application can use select(2), poll(2), or epoll(7) to determine when more data arrives on a socket.

Use packet(7) instead. Macro: int ENOEXEC Invalid executable file format. MSG_ERRQUEUE (since Linux 2.2) This flag specifies that queued errors should be received from the socket error queue. Errno.h In C MSG_WAITALL (since Linux 2.2) This flag requests that the operation block until the full request is satisfied.

Sockets of type SOCK_STREAM are full-duplex byte streams. Macro: int EHOSTUNREACH The remote host for a requested network connection is not reachable. 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). official site Macro: int EGRATUITOUS This error code has no purpose.

Macro: int EEXIST File exists; an existing file was specified in a context where it only makes sense to specify a new file. Errno.h Windows MSG_TRUNC indicates that the trailing portion of a datagram was discarded because the datagram was larger than the buffer supplied. If this address is not known, the sa_family member of the sockaddr contains AF_UNSPEC and the other fields of the sockaddr are undefined. It can contain several flags: MSG_EOR indicates end-of-record; the data returned completed a record (generally used with sockets of type SOCK_SEQPACKET).

Posix Error Codes

In GNU, this error is always synonymous with ENOMEM; you may get one or the other from network operations. SOCK_PACKET Obsolete and should not be used in new programs; see packet(7). Linux Errno Example Macro: int ENOLCK No locks available. Linux Recv EFAULT The receive buffer pointer(s) point outside the process's address space.

Macro: int ECONNRESET A network connection was closed for reasons outside the control of the local host, such as by the remote machine rebooting or an unrecoverable protocol violation. weblink It is equivalent to the call: recvfrom(fd, buf, len, flags, NULL, 0); recvmsg() The recvmsg() call uses a msghdr structure to minimize the number of directly supplied arguments. Macro: int EADDRNOTAVAIL The requested socket address is not available; for example, you tried to give a socket a name that doesn’t match the local host name. SOCK_RDM Provides a reliable datagram layer that does not guarantee ordering. Errno.h Linux Kernel

delete the numbers uniq -c created Should I accept a low hourly rate while in between contracts? 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 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. http://globalinfoindex.com/error-code/linux-error-code-1.php Linux 2016-07-17 RECV(2) Copyright and license for this manual page HTML rendering created 2016-10-08 by Michael Kerrisk, author of The Linux Programming Interface, maintainer of the Linux man-pages project.

You signed out in another tab or window. Strerror On error, -1 is returned, and errno is set appropriately. Did Pokemon start off as a Manga?

The protocol number to use is specific to the “communication domain” in which communication is to take place; see protocols(5).

This often indicates a cycle of symbolic links. The caller should set msg_namelen to the size of this buffer before this call; upon return from a successful call, msg_namelen will contain the length of the returned address. Embed Embed this gist in your website. Errno 0 See Asynchronous I/O.

Errors: Linux System Errors When system requests fail, error code are returned. Macro: int ENOENT No such file or directory. The operation of sockets is controlled by socket level options. http://globalinfoindex.com/error-code/linux-error-code-11.php Macro: int EBADMSG Macro: int EIDRM Macro: int EMULTIHOP Macro: int ENODATA Macro: int ENOLINK Macro: int ENOMSG Macro: int ENOSR Macro: int ENOSTR Macro: int EOVERFLOW Macro: int EPROTO Macro:

When recvmsg() is called, msg_controllen should contain the length of the available buffer in msg_control; upon return from a successful call it will contain the length of the control message sequence. 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. You can use perror in stdio.h to print an error message based on the value of errno or you can use strerror in string.h to access a string describing the error

However, on (very) old UNIX systems, there may be no and the declaration is needed. NOTES top If a zero-length datagram is pending, read(2) and recv() with a flags argument of zero provide different behavior. 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 SOCK_DGRAM and SOCK_RAW sockets allow sending of datagrams to correspondents named in sendto(2) calls.

Macro: int ENOTSUP Not supported.
