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
The underlying file system of the specified file
does not support memory 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.
