NAME
       towupper - transliterate lower-case wide-character code to upper-case

SYNOPSIS
       #include <wchar.h>

       wint_t towupper(wint_t wc);

DESCRIPTION
       The  towupper()	function  has as a domain a type wint_t, the value of which must be a character representable as a wchar_t, and must be  a
       wide-character code corresponding to a valid character in the current locale or the value of WEOF. If the argument has any other value, the
       argument  is  returned  unchanged.  If the argument of towupper() represents a lower-case wide-character code (as defined by character type
       information in the program locale category LC_CTYPE),   the result is the corresponding upper-case wide-character code. All other arguments
       in the domain are returned unchanged.

RETURN VALUES
       Upon  successful completion, towupper() returns the upper-case letter corresponding to the argument passed. Otherwise, it returns the argu-
       ment unchanged.

ERRORS
       No errors are defined.
