Socket Error Codes In Linux


Macro: int ENOTBLK A file that isn’t a block special file was given in a situation that requires one. On error, -1 is returned, and errno is set appropriately. This error is never generated by GNU/Hurd systems, but it can result from an operation to an NFS server running another operating system. Macro: int EUSERS The file quota system is confused because there are too many users. http://dualathlonserver.com/error-codes/socket-error-codes-linux.php

Valid error numbers are all nonzero; errno is never set to zero by any system call or library function. ENOTCONN The socket is not connected, and no target has been given. Macro: int ENOBUFS The kernel’s buffers for I/O operations are all in use. Better if you could help me by sending code in personel.

Linux Errno Example

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, ENOBUFS The output queue for a network interface was full. Portability Note: In many older Unix systems, this condition was indicated by EWOULDBLOCK, which was a distinct error code different from EAGAIN. CONFORMING TO top POSIX.1-2001, POSIX.1-2008, 4.4BSD.

The operation of sockets is controlled by socket level options. The MSG_CONFIRM flag is a Linux extension. type The original type, exactly as passed to the socket(2) system call. Enxio What to do when majority of the students do not bother to do peer grading assignment?

The only difference between send() and write(2) is the presence of flags. However, it is possible that many protocols may exist, in which case a particular protocol must be specified in this manner. Just download it and use it to solve this issue. SOCK_RAW Provides raw network protocol access.

Macro: int EAGAIN Resource temporarily unavailable; the call might work if you try again later. Enotsup Macro: int EPROCLIM This means that the per-user limit on new process would be exceeded by an attempted fork. man7.org > Linux > man-pages Linux/UNIX system programming training NAME | SYNOPSIS | DESCRIPTION | NOTES | SEEALSO | COLOPHON ERRNO(3) Linux Programmer's Manual ERRNO(3) NAME top In BSD and GNU, the number of open files is controlled by a resource limit that can usually be increased.

Posix Error Codes

The system cannot allocate more virtual memory because its capacity is full. http://man7.org/linux/man-pages/man2/socket.2.html 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 Linux Errno Example Macro: int ESRCH No process matches the specified process ID. Linux Errno To String This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno.

type The original type, exactly as passed to the socket(2) system call. http://dualathlonserver.com/error-codes/socket-programming-error-codes.php This function is intended to be used in a fashion similar to the following example: if (socket(domain, type, protocol) < 0) { int err = errno; fprintf(stderr, "%s\n", explain_errno_socket(err, domain, type, See Sockets. Macro: int EOPNOTSUPP The operation you requested is not supported. Errno.h Linux Kernel

  1. Macro: int EISDIR File is a directory; you cannot open a directory for writing, or create or remove hard links to it.
  2. When the message does not fit into the send buffer of the socket, send() normally blocks, unless the socket has been placed in nonblocking I/O mode.
  3. Does this email mean that I have been granted the visa?
  4. Typically, this error occurs when you are trying to delete a directory.

Macro: int ERPCMISMATCH ??? Macro: int ECONNREFUSED A remote host refused to allow the network connection (typically because it is not running the requested service). SOCK_PACKET Obsolete and should not be used in new programs; see packet(7). http://dualathlonserver.com/error-codes/socket-error-codes-unix.php 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

According to this: http://linux.die.net/man/2/socket the function returns -1 on failure, and sets errno to the appropriate error number. Errno.h Windows socket() appeared in 4.2BSD. errnum The error value to be decoded, usually obtained from the errno global variable just before this function is called.

Repairing this condition usually requires unmounting, possibly repairing and remounting the file system.

See getprotoent(3) on how to map protocol name strings to protocol numbers. On error, -1 is returned, and errno is set appropriately. The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library. Einval Errno Instead it would just exit the program.

Bugs Linux may return EPIPE instead of ENOTCONN.

This will be overwritten by the next call to any libexplain function which shares this buffer, including other threads. Read more about Ramesh Natarajan and the blog. But all the rest did! For sendmsg(), the address of the target is given by msg.msg_name, with msg.msg_namelen specifying its size.

EINVAL Invalid flags in type. Password Programming This forum is for all programming questions. Macro: int ED The experienced user will know what is wrong. For example, "Error no is : 17", which doesn't really say much.

For example, if you try to delete a file that is the root of a currently mounted filesystem, you get this error. A SIGPIPE signal is raised if a process sends or receives on a broken stream; this causes naive processes, which do not handle the signal, to exit. Macro: int ERESTART Macro: int ECHRNG Macro: int EL2NSYNC Macro: int EL3HLT Macro: int EL3RST Macro: int ELNRNG Macro: int EUNATCH Macro: int ENOCSI Macro: int EL2HLT Macro: int EBADE Macro: Macro: int ENFILE There are too many distinct file openings in the entire system.

Locally detected errors are indicated by a return value of -1.
