+more than once, so arguments given to

+should not be expressions with potential side effects.
+.Pp
+.Fn putwchar
+is identical to
+.Fn putwc
+with an output stream of
+.Em stdout .
+.Sh RETURN VALUES
+The functions,
+.Fn fputwc ,
+.Fn putwc
+and
+.Fn putwchar
+return the wide-character written.
+If an error occurs, the value
+.Dv WEOF
+is returned.
