Socket Error Code In Linux


O_CREAT flag is to create a file, if the file does not exist. 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). Macro: int ENODEV The wrong type of device was given to a function that expects a particular sort of device. Additional errors may be generated and returned from the underlying protocol modules; see their respective manual pages. weblink

Macro: int ETOOMANYREFS ??? See the description of the O_CLOEXEC flag in open(2) for reasons why this may be useful. Macro: int ENOENT No such file or directory. Macro: int EHOSTDOWN The remote host for a requested network connection is down. http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html

Posix Error Codes

The definition of the msghdr structure follows. The AF_ALG protocol type was added in Linux 2.6.38. Macro: int EIO Input/output error; usually used for physical read or write errors. Using F_SETOWN is equivalent to an ioctl(2) call with the FIOSETOWN or SIOCSPGRP argument.

  1. Macro: int EPROTONOSUPPORT The socket domain does not support the requested communications protocol (perhaps because the requested protocol is completely invalid).
  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.
  3. CONFORMING TO top POSIX.1-2001, POSIX.1-2008, 4.4BSD.

MSG_EOR (since Linux 2.2) Terminates a record (when this notion is supported, as for sockets of type SOCK_SEQPACKET). Bad File Number For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration.

But all the rest did! rename can cause this error if the file being renamed already has as many links as it can take (see Renaming Files). You can choose to have functions resume after a signal that is handled, rather than failing with EINTR; see Interrupted Primitives. look at this web-site The MSG_CONFIRM flag is a Linux extension.

In general, you should code like this: #include #include int main(void) { int s; s = socket(...); if (s < 0) { fprintf(stderr, "socket() failed: %s\n", strerror(errno)); exit(1); } Enotsup Macro: int ECONNREFUSED A remote host refused to allow the network connection (typically because it is not running the requested service). EXAMPLE top An example of the use of socket() is shown in getaddrinfo(3). This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files).

Linux Errno Example

fork can return this error. https://gist.github.com/gabrielfalcao/4216897 MSG_CONFIRM (Since Linux 2.3.15) Tell the link layer that forward progress happened: you got a successful reply from the other side. Posix Error Codes POSIX.1-2008 adds a specification of MSG_NOSIGNAL. Linux Errno To String The question does not have to be directly related to Linux and any language is fair game.

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. have a peek at these guys 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. ECONNRESET Connection reset by peer. SOCK_RDM Provides a reliable datagram layer that does not guarantee ordering. Errno.h Linux Kernel

To make your program portable, you should check for both codes and treat them the same. ENOBUFS The output queue for a network interface was full. Macro: int ENOMEM No memory available. check over here 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

According to this: http://linux.die.net/man/2/socket the function returns -1 on failure, and sets errno to the appropriate error number. Enxio Not the answer you're looking for? The functions setsockopt(2) and getsockopt(2) are used to set and get options, respectively.

It will allocate the addrinfo for you, which you pass to freeaddrinfo() to free it: result = NULL; iResult = getaddrinfo(..., &result); if (iResult == 0) { ...; freeaddrinfo(result); } –Remy

This error is never generated by GNU/Hurd systems, but it can result from an operation to an NFS server running another operating system. How can we define lots of variables Term for a toroidal-shaped, winter garment worn on the neck, not scarf, often made of polar fleece (pictures) Abstract definition of convex set My The EPIPE error is still returned. Errno.h Windows Instead it would just exit the program.

EPIPE The local end has been shut down on a connection oriented socket. Currently defined types are: SOCK_STREAM Provides sequenced, reliable, two-way, connection- based byte streams. Macro: int ERPCMISMATCH ??? http://unordic.com/error-code/socket-error-code-35.html You get this error when you try to transmit data over a socket, without first specifying a destination for the data.

The SOCK_NONBLOCK and SOCK_CLOEXEC flags are Linux-specific. 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. Macro: int EISCONN You tried to connect a socket that is already connected. When you are running some program on Linux environment, you might notice that it gives some error number.

Link bubrek November 3, 2010, 11:46 am i have to make stronge grip on C++ please help me by sending handout/notes and practices Link Cancel reply Leave a Comment Name Email EOPNOTSUPP Some bit in the flags argument is inappropriate for the socket type. But you gave nothing special more than formatting the contents of the linux errno headers. Macro: int EEXIST File exists; an existing file was specified in a context where it only makes sense to specify a new file.

Since Linux 2.6.27, the type argument serves a second purpose: in addition to specifying a socket type, it may include the bitwise OR of any of the following values, to modify Also all message boundaries in incoming datagrams are preserved. They are recorded in:- /usr/include/asm/errno.h Here is a copy of that file as of Aug 2004 on RedHat 7.3 #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* EDESTADDRREQ The socket is not connection-mode, and no peer address is set.

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 Macro: int ENOTSUP Not supported. Macro: int EFBIG File too big; the size of a file would be larger than allowed by the system. You are currently viewing LQ as a guest.

When you call aio_cancel, the normal result is for the operations affected to complete with this error; see Cancel AIO Operations.
