<%GLibFileError>
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.
alias 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.
alias G_FILE_ERROR_ISDIR
File is a directory; you cannot open a directory for writing, or create or remove hard links to it.
alias G_FILE_ERROR_ACCES
Permission denied; the file permissions do not allow the attempted operation.
alias 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.
alias G_FILE_ERROR_NOTDIR
A file that isn't a directory was specified when a directory is required.
alias 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.
alias G_FILE_ERROR_NODEV
The underlying file system of the specified file does not support memory mapping.
alias G_FILE_ERROR_ROFS
The directory containing the new link can't be modified because it's on a read-only file system.
alias 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.)
alias 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.
alias G_FILE_ERROR_NOSPC
No space left on device; write operation on a file failed because the disk is full.
alias G_FILE_ERROR_NOMEM
No memory available. The system cannot allocate more virtual memory because its capacity is full.
alias 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.
alias 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).
alias G_FILE_ERROR_INVAL
Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function.
alias 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'.
alias G_FILE_ERROR_AGAIN
Resource temporarily unavailable; the call might work if you try again later.
alias 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.
alias 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.
alias 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.
