POSIX defines two cases:

- The value of the oflag argument is not valid.
- The implementation does not support synchronized I/O for this file.

The latter is only applicable when the synchronized I/O extensions are
supported and any of the O_SYNC/O_DSYNC/O_RSYNC flags is used.

An implementation can define arbitrary extra cases in addition to the
ones mentioned by POSIX.
