Socket Error Code In Linux


Macro: int ELOOP Too many levels of symbolic links were encountered in looking up a file name. Macro: int EREMOTE An attempt was made to NFS-mount a remote file system with a file name that already specifies an NFS-mounted file. (This is an error on some operating systems, The protocol number to use is specific to the “communication domain” in which communication is to take place; see protocols(5). Typically, this error occurs when you are trying to delete a directory. http://phabletkeyboards.com/error-code/socket-error-code-linux.php

Posix Error Codes

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 The man page for many library functions will indicate that they return -1 on error, and set errno. But you gave nothing special more than formatting the contents of the linux errno headers.

Macro: int EHOSTUNREACH The remote host for a requested network connection is not reachable. According to POSIX.1-2001, the msg_controllen field of the msghdr structure should be typed as socklen_t, but glibc currently types it as size_t. Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started Bad File Number Some socket types may not be implemented by all protocol families.

Macro: int EBUSY Resource busy; a system resource that can’t be shared is already in use. Linux Errno Example Often using a debugger to run a program is considered having it open for writing and will cause this error. (The name stands for “text file busy”.) This is not an When SO_KEEPALIVE is enabled on the socket the protocol checks in a protocol-specific manner if the other end is still alive. Using this flag saves extra calls to fcntl(2) to achieve the same result.

errno values are set when the return code is negative. Enotsup MSG_MORE (Since Linux 2.4.4) The caller has more data to send. MSG_OOB Sends out-of-band data on sockets that support this notion (e.g., of type SOCK_STREAM); the underlying protocol must also support out-of-band data. See Socket Options.

Linux Errno Example

Some functions that must always block (such as connect; see Connecting) never return EAGAIN. Get More Information Also, the following call send(sockfd, buf, len, flags); is equivalent to sendto(sockfd, buf, len, flags, NULL, 0); The argument sockfd is the file descriptor of the sending socket. Posix Error Codes Macro: int ESRCH No process matches the specified process ID. Linux Errno To String SOCK_RDM Provides a reliable datagram layer that does not guarantee ordering.

If the entire function is not available at all in the implementation, it returns ENOSYS instead. http://phabletkeyboards.com/error-code/socket-error-code-eagain.php SOCK_DGRAM and SOCK_RAW sockets allow sending of datagrams to correspondents named in sendto(2) calls. I hope this would help. Make sure to bookmark this article for future reference. Errno.h Linux Kernel

EIBMSOCKOUTOFRANGE 1002 Socket number assigned by client interface code (for socket() and accept()) is out of range EIBMSOCKINUSE 1003 Socket number assigned by client interface code is already in use EIBMIUCVERR

Macro: int ECHILD There are no child processes. Macro: int ENOPROTOOPT You specified a socket option that doesn’t make sense for the particular protocol being used by the socket. rename can cause this error if the file being renamed already has as many links as it can take (see Renaming Files). Errno.h Windows 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.

Using F_SETOWN is equivalent to an ioctl(2) call with the FIOSETOWN or SIOCSPGRP argument. 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 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). this content See Connecting.

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 The system does not guarantee that it will notice all such situations. Other errors may be generated by the underlying protocol modules. Macro: int EACCES Permission denied; the file permissions do not allow the attempted operation.

Macro: int ENOTCONN The socket is not connected to anything.

Macro: int EAGAIN Resource temporarily unavailable; the call might work if you try again later.

Is there a way to easily handle functions returning std::pairs? This error is never generated by GNU/Hurd systems, but it can result from an operation to an NFS server running another operating system. There are two flags in the open call.
