FileError

Description:

[ CCode ( has_type_id = false ) ]
public errordomain FileError

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.

Error codes:

  • ACCES - Permission denied; the file permissions do not allow the attempted operation.
  • AGAIN - Resource temporarily unavailable; the call might work if you try again later.
  • 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).
  • EXIST - Operation not permitted; only the owner of the file (or other resource) or processes with special privileges can perform the operation.
  • FAILED - Does not correspond to a UNIX error code; this is the standard "failed for unspecified reason" error code present in all Error error code enumerations.
  • FAULT - You passed in a pointer to bad memory.
  • INTR - Interrupted function call; an asynchronous signal occurred and prevented completion of the call.
  • INVAL - Invalid argument.
  • IO - Input/output error; usually used for physical read or write errors.
  • ISDIR - File is a directory; you cannot open a directory for writing, or create or remove hard links to it.
  • LOOP - Too many levels of symbolic links were encountered in looking up a file name.
  • MFILE - The current process has too many files open and can't open any more.
  • NAMETOOLONG - Filename too long.
  • NFILE - There are too many distinct file openings in the entire system.
  • NODEV - The underlying file system of the specified file does not support memory mapping.
  • NOENT - No such file or directory.
  • NOMEM - No memory available.
  • NOSPC - No space left on device; write operation on a file failed because the disk is full.
  • NOSYS - Function not implemented; this indicates that the system is missing some functionality.
  • NOTDIR - A file that isn't a directory was specified when a directory is required.
  • NXIO - No such device or address.
  • PERM - Operation not permitted; only the owner of the file (or other resource) or processes with special privileges can perform the operation.
  • PIPE - Broken pipe; there is no process reading from the other end of a pipe.
  • ROFS - The directory containing the new link can't be modified because it's on a read-only file system.
  • TXTBSY - Text file busy.
