file open error codes Los Alamos, New Mexico

Some of these error codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. In general, the behavior of O_EXCL is undefined if it is used without O_CREAT. 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. From this errno variable you can use some error handling functions to find out the error description and handle it appropriately.

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 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. RT043 File information missing for indexed file. Check your computer's system information and then contact the software publisher. ERROR_EXE_CANNOT_MODIFY_SIGNED_BINARY 217 (0xD9) The image file %1 is signed, unable to modify. ERROR_EXE_CANNOT_MODIFY_STRONG_SIGNED_BINARY 218 (0xDA) The image file

If opened I-O the file was created. It is recommended that applications treat use of O_DIRECT as a performance option which is disabled by default. "The thing that has always disturbed me about O_DIRECT is that the whole Isn't that more expensive than an elevated system? The distinction between these two groups of flags is that the file status flags can be retrieved and (in some cases) modified; see fcntl(2) for details.

Macro: int ENOLCK No locks available. Due to the nature of this virus or potentially unwanted software, the file has been removed from this location. ERROR_PIPE_LOCAL 229 (0xE5) The pipe is local. ERROR_BAD_PIPE 230 (0xE6) For example, if you try to delete a file that is the root of a currently mounted filesystem, you get this error. If joining a workgroup, choose another workgroup name. ERROR_BAD_NETPATH 53 (0x35) The network path was not found. ERROR_NETWORK_BUSY 54 (0x36) The network is busy. ERROR_DEV_NOT_EXIST 55 (0x37) The

The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library. O_DIRECTORY If pathname is not a directory, cause the open to fail. Macro: int ESPIPE Invalid seek operation (such as on a pipe). RT015 Too many indexed files open.

This error never occurs on GNU/Hurd systems. The full list of file creation flags and file status flags is as follows: O_APPEND The file is opened in append mode. To save myself, and a few others, some time in the future... /usr/include/asm-generic/errno-base.h #ifndef _ASM_GENERIC_ERRNO_BASE_H #define _ASM_GENERIC_ERRNO_BASE_H #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such Use of these codes requires some amount of investigation and analysis.

Duplicate descriptors do count toward this limit. See section J.4, "Transaction Error Codes". 9ZThis run-time has a limit on the number of records that can be processed and that limit has been exceeded. (Any) File Structures File Handling Before each write(2), the file offset is positioned at the end of the file, as if with lseek(2). How do I find the error or the reason for the file not opening.

O_EXCL Ensure that this call creates the file: if this flag is specified in conjunction with O_CREAT, and pathname already exists, then open() will fail. Browse other questions tagged c linux file-io errno or ask your own question. Macro: int ENOBUFS The kernel’s buffers for I/O operations are all in use. RT066 Attempt to add duplicate record key to indexed file.

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. Macro: int ENOENT No such file or directory. In multithreaded programs it is a macro executing a function that returns the last error of the caller thread. 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

IRIX has also a fcntl(2) call to query appropriate alignments, and sizes. RT004 Illegal file name. If pathname is relative and dirfd is the special value AT_FDCWD, then pathname is interpreted relative to the current working directory of the calling process (like open()). RETURN VALUE top open(), openat(), and creat() return the new file descriptor, or -1 if an error occurred (in which case, errno is set appropriately).

Macro: int EFTYPE Inappropriate file type or format. On Linux, one can use the kcmp(2) KCMP_FILE operation to test whether two file descriptors (in the same process or in two different processes) refer to the same open file description. If the block device is in use by the system (e.g., mounted), open() fails with the error EBUSY. Join them; it only takes a minute: Sign up Error on file open: File exists up vote -4 down vote favorite The return value of an open() was -1 and on

This is typically used to open devices in order to get a file descriptor for use with ioctl(2). On Linux, the following bits are also honored in mode: S_ISUID 0004000 set-user-ID bit S_ISGID 0002000 set-group-ID bit (see stat(2)) S_ISVTX 0001000 sticky bit (see stat(2)) O_DIRECT (since Linux 2.4.10) Try For example, "Error no is : 17", which doesn't really say much. Macro: int ENOPROTOOPT You specified a socket option that doesn’t make sense for the particular protocol being used by the socket.

If the pathname given in pathname is relative, then it is interpreted relative to the directory referred to by the file descriptor dirfd (rather than relative to the current working directory Cyberpunk story: Black samurai, skateboarding courier, Mafia selling pizza and Sumerian goddess as a computer virus What's the most recent specific historical element that is common between Star Trek and the Macro: int ECONNABORTED A network connection was aborted locally. The client asks the server to make the I/O synchronous to preserve the synchronous semantics of O_DIRECT.

Note that any number of linked channels count as just one file opening; see Linked Channels. When both O_CREAT and O_DIRECTORY are specified in flags and the file specified by pathname does not exist, open() will create a regular file (i.e., O_DIRECTORY is ignored). Macro: int EPROGMISMATCH ??? O_TMPFILE must be specified with one of O_RDWR or O_WRONLY and, optionally, O_EXCL.

ENXIO The file is a device special file and no corresponding device exists. ERRORS top open(), openat(), and creat() can fail with the following errors: EACCES The requested access to the file is not allowed, or search permission is denied Attempts to manipulate the object before the call completes return EALREADY. The file descriptor returned by a successful call will be the lowest-numbered file descriptor not currently open for the process.

To guarantee synchronous I/O, O_SYNC must be used in addition to O_DIRECT. A file descriptor is a reference to an open file description; this reference is unaffected if pathname is subsequently removed or modified to refer to a different file.
