GFileError

Values corresponding to errno codes returned from file operations on UNIX. Unlike errno codes, GFileError values are available on all systems, even Windows. The exact meaning of each code depends on what sort of file operation you were performing; the UNIX documentation gives more details. The following error code descriptions come from the GNU C Library manual, and are under the copyright of that manual. It's not very portable to make detailed assumptions about exactly which errors will be returned from a given operation. Some errors don't occur on some systems, etc., sometimes there are subtle differences in when a system will report a given error, etc. G_FILE_ERROR_EXIST Operation not permitted; only the owner of the file (or other resource) or processes with special privileges can perform the operation. G_FILE_ERROR_ISDIR File is a directory; you cannot open a directory for writing, or create or remove hard links to it. G_FILE_ERROR_ACCES Permission denied; the file permissions do not allow the attempted operation. G_FILE_ERROR_NAMETOOLONG Filename too long. G_FILE_ERROR_NOENT No such file or directory. This is a "file doesn't exist" error for ordinary files that are referenced in contexts where they are expected to already exist. G_FILE_ERROR_NOTDIR A file that isn't a directory was specified when a directory is required. G_FILE_ERROR_NXIO No such device or address. The system tried to use the device represented by a file you specified, and it couldn't find the device. This can mean that the device file was installed incorrectly, or that the physical device is missing or not correctly attached to the computer. G_FILE_ERROR_NODEV This file is of a type that doesn't support mapping. G_FILE_ERROR_ROFS The directory containing the new link can't be modified because it's on a read-only file system. G_FILE_ERROR_TXTBSY Text file busy. G_FILE_ERROR_FAULT You passed in a pointer to bad memory. (GLib won't reliably return this, don't pass in pointers to bad memory.) G_FILE_ERROR_LOOP Too many levels of symbolic links were encountered in looking up a file name. This often indicates a cycle of symbolic links. G_FILE_ERROR_NOSPC No space left on device; write operation on a file failed because the disk is full. G_FILE_ERROR_NOMEM No memory available. The system cannot allocate more virtual memory because its capacity is full. G_FILE_ERROR_MFILE The current process has too many files open and can't open any more. Duplicate descriptors do count toward this limit. G_FILE_ERROR_NFILE There are too many distinct file openings in the entire system. G_FILE_ERROR_BADF Bad file descriptor; for example, I/O on a descriptor that has been closed or reading from a descriptor open only for writing (or vice versa). G_FILE_ERROR_INVAL Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function. G_FILE_ERROR_PIPE Broken pipe; there is no process reading from the other end of a pipe. Every library function that returns this error code also generates a `SIGPIPE' signal; this signal terminates the program if not handled or blocked. Thus, your program will never actually see this code unless it has handled or blocked `SIGPIPE'. G_FILE_ERROR_AGAIN Resource temporarily unavailable; the call might work if you try again later. G_FILE_ERROR_INTR Interrupted function call; an asynchronous signal occurred and prevented completion of the call. When this happens, you should try the call again. G_FILE_ERROR_IO Input/output error; usually used for physical read or write errors. i.e. the disk or other physical device hardware is returning errors. G_FILE_ERROR_PERM Operation not permitted; only the owner of the file (or other resource) or processes with special privileges can perform the operation. G_FILE_ERROR_NOSYS Function not implemented; this indicates that the system is missing some functionality. G_FILE_ERROR_FAILED Does not correspond to a UNIX error code; this is the standard "failed for unspecified reason" error code present in all GError error code enumerations. Returned if no specific code applies.
