+DESCRIPTION
+Use <<fgetwc>> to get the next wide character from the file or stream
+identified by <[fp]>.  As a side effect, <<fgetwc>> advances the file's
+current position indicator.
+
+The  <<getwc>>  function  or macro functions identically to <<fgetwc>>.  It
+may be implemented as a macro, and may evaluate its argument more  than
+once. There is no reason ever to use it.
+
+<<_fgetwc_r>> and <<_getwc_r>> are simply reentrant versions of
+<<fgetwc>> and <<getwc>> that are passed the additional reentrant
+structure pointer argument: <[ptr]>.
+
+RETURNS
+The next wide character cast to <<wint_t>>), unless there is no more data,
+or the host system reports a read error; in either of these situations,
+<<fgetwc>> and <<getwc>> return <<WEOF>>.
+
+You can distinguish the two situations that cause an <<EOF>> result by
+using the <<ferror>> and <<feof>> functions.

+DESCRIPTION
+<<fputwc>> writes the wide character argument <[wc]> to the file or
+stream identified by <[fp]>.
+
+If the file was opened with append mode (or if the stream cannot
+support positioning), then the new wide character goes at the end of the
+file or stream.  Otherwise, the new wide character is written at the
+current value of the position indicator, and the position indicator
+oadvances by one.
+
+The <<putwc>> function or macro functions identically to <<fputwc>>.  It
+may be implemented as a macro, and may evaluate its argument more than
+once. There is no reason ever to use it.
+
+The <<_fputwc_r>> and <<_putwc_r>> functions are simply reentrant versions
+of <<fputwc>> and <<putwc>> that take an additional reentrant structure
+argument: <[ptr]>.
+
+RETURNS
+If successful, <<fputwc>> and <<putwc>> return their argument <[wc]>.
+If an error intervenes, the result is <<EOF>>.  You can use
+`<<ferror(<[fp]>)>>' to query for errors.

+	FILE *<[fp]>;
+	int <[mode]>;
+
+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.

+
+DESCRIPTION
+The <<putwchar(>> function or macro is the wide-character equivalent of
+the <<putchar>> function. It writes the wide character wc to stdout.
+
+The alternate function <<_putwchar_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+If successful, <<putwchar>> returns its argument <[wc]>.  If an error
+intervenes, the result is <<EOF>>.  You can use `<<ferror(stdin)>>' to
+query for errors.

+
+DESCRIPTION
+<<ungetwc>> is used to return wide characters back to <[stream]> to be
+read again.  If <[wc]> is WEOF, the stream is unchanged.  Otherwise, the
+wide character <[wc]> is put back on the stream, and subsequent reads will see
+the wide chars pushed back in reverse order.  Pushed wide chars are lost if the
+stream is repositioned, such as by <<fseek>>, <<fsetpos>>, or
+<<rewind>>.
+
+The underlying file is not changed, but it is possible to push back
+something different than what was originally read.  Ungetting a
+character will clear the end-of-stream marker, and decrement the file
+position indicator.  Pushing back beyond the beginning of a file gives
+unspecified behavior.
+
+The alternate function <<_ungetwc_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+The wide character pushed back, or <<WEOF>> on error.
