But these aren't really enough, developers should try harder to tell the user what's going on and give them ways of fixing or working around the problem. 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definitely can't help you track those down.EDOM -- The input argument is Historical applications (that is, horribly outdated legacy code) sometimes refer to these directly, but produce errors during compilation because they're declared inconsistently.The POSIX standard defines quite a few possible values for Macro: int ENOLCK No locks available. http://dssoundware.com/error-codes/enosys-error.php
Why aren't Muggles extinct? Remember that file descriptors include things like sockets.ENLINK -- The function call would cause a file to have more than LINK_MAX links.ENAMETOOLONG -- You've created a path name longer than PATH_MAX, When you call aio_cancel, the normal result is for the operations affected to complete with this error; see Cancel AIO Operations. Macro: int ECONNRESET A network connection was closed for reasons outside the control of the local host, such as by the remote machine rebooting or an unrecoverable protocol violation. http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html
Macro: int ENOTSUP Not supported. To translate a numeric error code to an error message, use os.strerror(). Macro: int ENODEV The wrong type of device was given to a function that expects a particular sort of device. This error never occurs on GNU/Hurd systems.

This often indicates a cycle of symbolic links. Posix Error Codes Share: Chris Herborth ([email protected]), Freelance Writer, Author Close [x] Chris Herborth is an award-winning Senior Technical Writer with more than 10 years of experience writing about operating systems and programming. Macro: int ENETDOWN A socket operation failed because the network was down. Macro: int EMFILE The current process has too many files open and can’t open any more.
Close [x] Choose your display name The first time you sign in to developerWorks, a profile is created for you, so you need to choose a display name. Enxio Note: You can't assume that the value of errno is valid unless the function that you've called indicates that an error has occurred. Macro: int ENOTTY Inappropriate I/O control operation, such as trying to set terminal modes on an ordinary file. Each process has OPEN_MAX file descriptors, and you're trying to open (OPEN_MAX + 1) files.
Macro: int ESHUTDOWN The socket has already been shut down. http://www.qnx.com/developers/docs/660/topic/com.qnx.doc.neutrino.lib_ref/topic/e/errno.html 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. Linux Kernel Error Codes This change could cause incompatibility problems in code that's been compiled with the old value of EALREADY. C Programming Error Codes Note the ambiguity between EBUSY and EAGAIN; obviously you'd be able to remove the directory later, when the reading program has finished.ECHILD -- The wait() or waitpid() function tried to wait
A function returns this error when certain parameter values are valid, but the functionality they request is not available. Macro: int EPROGUNAVAIL ??? What is Eclipse, and how do I use it? (developerWorks, November 2001): Read this article for an introduction to the Eclipse platform. Macro: int EISCONN You tried to connect a socket that is already connected. Eintr Errno
Not the answer you're looking for? Eintr Signal Valid error numbers are all nonzero; errno is never set to zero by any system call or library function. Macro: int ENOTBLK A file that isn’t a block special file was given in a situation that requires one.
The work arround is to rebuild the kenel with POSIX MESSGE QUEUE enabled in the kernel configuration.

The Python Software Foundation is a non-profit corporation. Some of these error codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. ESTALE Potentially recoverable I/O error ESTRPIPE If pipe/FIFO, don't sleep in stream head ETIME Timer expired ETIMEDOUT Connection timed out ETOOMANYREFS Too many references: can't splice ETXTBSY Text file is busy The lack of exceptions from the C language and the rudimentary error mechanisms from the standard C library certainly contribute to this.
This is generally around 2GB, but most modern file systems support much larger files, sometimes requiring 64-bit versions of the read()/write() and lseek() functions.EINTR -- The function was interrupted by a 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. This can mean that the device file was installed incorrectly, or that the physical device is missing or not correctly attached to the computer. C libraries in many older Unix systems have EWOULDBLOCK as a separate error code.
