However, on (very) old UNIX systems, there may be no
Macro: int ENETRESET A network connection was reset because the remote host crashed. The cygwin guys have tried this for years. See Sockets. For example, if you try to delete a file that is the root of a currently mounted filesystem, you get this error.
Typically, this error occurs when you are trying to delete a directory. RagoGeen voorbeeld beschikbaar - 1993Veelvoorkomende woorden en zinsdelenallocate applications bp->bwptr bytes caller char client connect indications connect request connection-oriented contains create daemon data link data structures define disconnect DLPI drivers and All the error names specified by POSIX.1 must have distinct values, with the exception of EAGAIN and EWOULDBLOCK, which may be the same. Rago, one of the Bell Laboratories developers who built UNIX System V, Release 4, currently works as a manger at EMC, specializing in file servers and file systems.
On Unix, the directory is deleted without throwing an exception. And it also means that the descriptions of what might cause a specific error are heavily dependent on that word "might". When this happens, you should try the call again. Errno.h Windows That's the purpose of this error, though it is also used for the pause() function and some IPC functions. #define EIO 5 /* I/O error */ The catchall for all manner
Every library function that returns this error code also generates a SIGPIPE signal; this signal terminates the program if not handled or blocked. Attempts to manipulate the object before the call completes return EALREADY. Duplicate descriptors do count toward this limit. A destroyed mutex object can be re-initialised using pthread_mutex_init(); the results of otherwise referencing the object after it has been destroyed are undefined.
errno is thread-local; setting it in one thread does not affect its value in any other thread. Errno.h Linux Kernel See Fork failing, but WHY?? 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. The article was very informative and was a great help.
Streams use this if you attempt to link a stream onto itself. http://unix.superglobalmegacorp.com/Net2/newsrc/sys/errno.h.html The link() function also fails with EEXIST if the "new" file is not. #define EXDEV 18 /* Cross-device link */ You can't link across filesystems (that's what symbolic links are for). Linux Socket Error Codes Macro: int E2BIG Argument list too long; used when the arguments passed to a new program being executed with one of the exec functions (see Executing a File) occupy too much Linux Errno Example This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files).
In BSD and GNU, the number of open files is controlled by a resource limit that can usually be increased. So will tcdrain(), tcflush(), tcflow() and tcsendbreak(). #define ETXTBSY 26 /* Text file busy */ A "text" file is a program- an executing binary. On BSD platforms, bind() can return this when trying to bind a reserved port number if all are in use. 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 Linux Errno To String
A function returns this error when certain parameter values are valid, but the functionality they request is not available. Macro: int EPERM Operation not permitted; only the owner of the file (or other resource) or processes with special privileges can perform the operation. The file was the wrong type for the operation, or a data file had the wrong format. Macro: int EIEIO Go home and have a glass of warm, dairy-fresh milk.
Macro: int EBUSY Resource busy; a system resource that can’t be shared is already in use. Enxio Macro: int ENOENT No such file or directory. Macro: int EMSGSIZE The size of a message sent on a socket was larger than the supported maximum size.
On some systems chmod returns this error if you try to set the sticky bit on a non-directory file; see Setting Permissions. Richard Stevens,Stephen A. Tue Apr 6 16:28:27 2010: 8376 TonyLawrence I came across this recently: Universal Error Numbering System: (link) Probably won't go anywhere, but there it is. ------------------------ Printer Friendly Version Site Errno 0 Below is a list of the symbolic error names that are defined on Linux.
Although less likeky in practice, trying to remove a directory that has a filesystem mounted on it will also complain in this manner. More typically it would be on calling shmsys(), any of the xsd*() functions, and on attempting certain ioctls with the APM stuff. Macro: int ENOTEMPTY Directory not empty, where an empty directory was expected. SEE ALSO top errno(1), err(3), error(3), perror(3), strerror(3) COLOPHON top This page is part of release 4.08 of the Linux man-pages project.
Macro: int ENETDOWN A socket operation failed because the network was down. Candidates include the System V shared memory driver ("shm"), the Xenix shared data driver ("xsd"), and the Advanced Power Management drivers ("uapm" and "pwr"). Note that any number of linked channels count as just one file opening; see Linked Channels. C libraries in many older Unix systems have EWOULDBLOCK as a separate error code.
Trying to delete a non-existent route from the routing table also uses this. #define EINTR 4 /* Interrupted system call */ When a program reads from a "slow" device (a terminal,
