-DESCRIPTION
-When <[mode]> is zero, the <<fwide>> function determines the current
-orientation of <[fp]>. It returns a value > 0 if <[fp]> is
-wide-character oriented, i.e. if wide character I/O is permitted but
-char I/O is disallowed. It returns a value < 0 if <[fp]> is byte
-oriented, i.e. if char I/O is permitted but wide character I/O is
-disallowed. It returns zero if <[fp]> has no orientation yet; in
-this case the next I/O operation might change the orientation (to byte
-oriented if it is a char I/O operation, or to wide-character oriented
-if it is a wide character I/O operation).
-
-Once a stream has an orientation, it cannot be changed and persists
-until the stream is closed, unless the stream is re-opened with freopen,
-which removes the orientation of the stream.
-
-When <[mode]> is non-zero, the <<fwide>> function first attempts to set
-<[fp]>'s orientation (to wide-character oriented if <[mode]> > 0, or to
-byte oriented if <[mode]> < 0). It then returns a value denoting the
-current orientation, as above.
-
-RETURNS
-The <<fwide>> function returns <[fp]>'s orientation, after possibly
-changing it. A return value > 0 means wide-character oriented. A return
-value < 0 means byte oriented. A return value of zero means undecided.
-
-PORTABILITY
-C99, POSIX.1-2001.
