Unix File Error Numbers


It is probably a good idea to delay for a few seconds before trying it again, to allow time for other processes to release scarce resources. If the entire function is not available at all in the implementation, it returns ENOSYS instead. Required fields are indicated with an asterisk (*). Most implementations can't detect this (your program receives a SIGSEGFAULT signal and exit instead).EFBIG -- The request would cause a file to expand past the implementation-defined maximum file size. have a peek here

For some system calls and library functions (e.g., getpriority(2)), -1 is a valid return on success. But you gave nothing special more than formatting the contents of the linux errno headers. You could explain more each error so that beginners really get the problem behind it (even if it is generic).

Linux Errno Codes

IBM ID:*Need an IBM ID? Note that it isn't guaranteed that any given program will use these return values. 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 For example, if you call mkdir() with a path that names an existing file or directory.EFAULT -- One of the function arguments refers to an invalid address.

All OSes require that. –Keith Feb 28 '11 at 7:32 I am not sure about the general question.

Bad File Number Note that this is not the sort of deadlock you get in multithreaded code -- errno and its friends definitely can't help you track those down.EDOM -- The input argument is

If the value of errno should be preserved across a library call, it must be saved: if (somecall() == -1) { int errsv = errno; printf("somecall() failed\n"); if (errsv == ...) You get this error when you try to transmit data over a socket, without first specifying a destination for the data. If you have a numerical value, call the standard library function strerror or perror to obtain the corresponding error message (in your current locale). http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html Seekers of Perl Wisdom Cool Uses for Perl Meditations PerlMonks Discussion Categorized Q&A Tutorials Obfuscated Code Perl Poetry Perl News about Information?

Macro: int ECONNREFUSED A remote host refused to allow the network connection (typically because it is not running the requested service). Errno.h In C Macro: int ENETDOWN A socket operation failed because the network was down. What is way to eat rice with hands in front of westerners such that it doesn't appear to be yucky? Using >!

  • I never knew that.
  • This condition is detected by the exec functions; see Executing a File.
  • The way of indicating an end-of-file on the default standard input, a terminal, is usually .
  • Examples: % who > names Redirect standard output to a file named names % (pwd; ls -l) > out Redirect output of both commands to a file named out % pwd;

Below is a list of the symbolic error names that are defined on Linux. Posix Error Codes

This can mean that the function does not implement a particular command or option value or flag bit at all. Your display name accompanies the content you post on developerWorks. A good puzzle will wake me up Many. Check This Out For example, trying to mount an ordinary file as a file system in Unix gives this error.

The example shows redirection of both output and errors: % who >& /dev/null To redirect standard error and output to different files, you can use grouping: % (cat myfile > myout) Errno.h Linux Kernel Oh, it's from MySQL, not everybody has this. –Gilles Feb 28 '11 at 21:31 @Gilles D'oh, you beat me to the perl version! ;-) –Mikel Feb 28 '11 at 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).

Hosting by jambit GmbH. When errno is set to 0, you've encountered no problems, except you can't refer to this with a standard symbolic constant. Macro: int ENOSPC No space left on device; write operation on a file failed because the disk is full. Errno.h Windows The user running the program doesn't have permission to access a file, directory, and so forth.EAGAIN -- The required resource is temporarily unavailable; if you try the operation again later, it

You can use select to find out when the operation will be possible; see Waiting for I/O. http://crimsonskysoftware.com/linux-errno/unix-socket-error-numbers.html You can simulate this yourself by using a printf() call and the strerror() function, which returns a pointer to the textual representation of the current errno value.One detail you can't see

See Connecting. Macro: int ETIMEDOUT A socket operation with a specified timeout received no response during the timeout period. Macro: int EBACKGROUND On GNU/Hurd systems, servers supporting the term protocol return this error for certain operations when the caller is not in the foreground process group of the terminal.

The Finslerian version of the Nash embedding theorem What do you call someone without a nationality? Password:*Forgot your password?Change your password Keep me signed in. All of them expand into integer constant values. The file was the wrong type for the operation, or a data file had the wrong format.

The system tried to use the device represented by a file you specified, and it couldn’t find the device. Showing the declaration of errnoIn addition to noticing that my tab settings don't match those of whoever wrote this file, you'll see several of the standard error values, their symbolic names, The output looks like the following: $ errno 123 ENOMEDIUM 123 /* No medium found */ $ errno 111 ECONNREFUSED 111 /* Connection refused */ $ errno 122 EDQUOT 122 /* Macro: int EDOM Domain error; used by mathematical functions when an argument value does not fall into the domain over which the function is defined.

Macro: int EMLINK Too many links; the link count of a single file would become too large. Macro: int EMSGSIZE The size of a message sent on a socket was larger than the supported maximum size. On most systems, they're in /usr/include/errno.h or a file that it includes.

This is used by the file locking facilities; see File Locks.
