rename can cause this error if the file being renamed already has as many links as it can take (see Renaming Files). For example, the value given for the origin when positioning a file pointer (by means of a call to fseek) is before the beginning of the file.EMFILEToo many open files. Identifying a Star Trek TNG episode by text passage occuring in Carbon Based Lifeforms song "Neurotransmitter" How to make denominator of a complex expression real? See Socket Options.

Posix Error Codes

All of them expand into integer constant values. Macro: int ENOTSOCK A file that isn’t a socket was specified when a socket is required. Macro: int ENOSPC No space left on device; write operation on a file failed because the disk is full. A temporary resource shortage made an operation impossible.

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 Or you could call select(2) to wait until the socket is writeable and then try again. Macro: int EACCES Permission denied; the file permissions do not allow the attempted operation. Efault How much should the average mathematician know about foundations?

Generic Operating System Services » 15.16. errno -- Standard errno system symbols¶ This module makes available standard errno system symbols. This is a variable in libc that's set to either the old or new value, based on a system-wide configuration parameter. Some functions that must always block (such as connect; see Connecting) never return EAGAIN. Macro: int EAUTH ???

Symbols available can include: errno.EPERM¶ Operation not permitted errno.ENOENT¶ No such file or directory errno.ESRCH¶ No such process errno.EINTR¶ Interrupted system call errno.EIO¶ I/O error errno.ENXIO¶ No such device or address Enxio 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 Forum Operations by The UNIX and Linux Forums Developer Network Developer Network Developer Sign in MSDN subscriptions Get tools Downloads Visual Studio MSDN subscription access SDKs Trial software Free downloads Office Cartesian vs.

Posix Error Codes 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. Linux Errno To String Macro: int EHOSTUNREACH The remote host for a requested network connection is not reachable.

For functions that operate on some object given in a parameter, such as a file descriptor or a port, it might instead mean that only that specific object (file descriptor, port, http://dssoundware.com/error-code/er-dh-error-code.php Macro: int ENAMETOOLONG Filename too long (longer than PATH_MAX; see Limits for Files) or host name too long (in gethostname or sethostname; see Host Identification). If your code returns an EALREADY error, modify it to return EALREADY_DYNAMIC instead. In C programming language, there is no direct support for error handling. Errno.h Windows

See Limits on Resources, for details on the RLIMIT_NPROC limit. http://dssoundware.com/error-code/e50-error-code.php 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

If the entire function is not available at all in the implementation, it returns ENOSYS instead. Ebadf When this happens, you should try the call again. Or you can go through the man pages on your system.

Such shortages are usually fairly serious and affect the whole system, so usually an interactive program should report the error to the user and return to its command loop.

If so, is there a reference procedure somewhere? 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 The perror function is infinitely useful when dealing with errno (but sadly renders the point of this huge table mute). Errno.h Linux Kernel To translate a numeric error code to an error message, use os.strerror().

secondly i m not sure but probably check buff size like below if is already predefined Code: getconf -a |grep SOCK_MAXBUF and set and get send/rec buff size maybe try like In next execution, it throws an error number 17, which is "File already exist". This change could cause incompatibility problems in code that's been compiled with the old value of EALREADY. http://dssoundware.com/error-code/e62-10-error-code.php A function returns this error when certain parameter values are valid, but the functionality they request is not available.

I don't know of an online resource that lists system calls and error codes on a single page — it would be a big page. –Jonathan Leffler Sep 7 '14 at When you are running some program on Linux environment, you might notice that it gives some error number. You can use the -e option to procnto to specify the value of EALREADY_DYNAMIC: -eo Use the old value, which is the same as that of EBUSY. -en Use the POSIX-compliant 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 ENOTTY Inappropriate I/O control operation, such as trying to set terminal modes on an ordinary file. Macro: int ECHILD There are no child processes. You get this error when you try to transmit data over a socket, without first specifying a destination for the data. An attempt has been made to create a file that already exists.

Macro: int EPROGUNAVAIL ??? In order to allow applications to safely make the transition to the new value, we've modified to define a number of new symbolic values: EALREADY_OLD The old value (16).
