@defun set-file-modes filename mode
This function sets mode bits of @var{filename} to @var{mode} (which
must be an integer). Only the low 12 bits of @var{mode} are used.
On MS-DOS and MS-Windows, these functions (like the function that
actually operate on files) accept MS-DOS or MS-Windows file-name syntax,
where backslashes separate the components, as well as Unix syntax; but
-they always return Unix syntax. On VMS, these functions (and the ones
-that operate on files) understand both VMS file-name syntax and Unix
-syntax. This enables Lisp programs to specify file names in Unix syntax
-and work properly on all systems without change.
