NAME
       towupper - convert a wide character to uppercase


SYNOPSIS
       #include <wctype.h>

       wint_t towupper(wint_t wc);


DESCRIPTION
       The  towupper()  function  is  the wide-character equivalent of the toupper(3) function.  If wc is a wide
       character, it is converted to uppercase.  Characters which do not have case are returned  unchanged.   If
       wc is WEOF, WEOF is returned.


RETURN VALUE
       The towupper() function returns the uppercase equivalent of wc, or WEOF if wc is WEOF.


CONFORMING TO
       C99.


NOTES
       The behavior of towupper() depends on the LC_CTYPE category of the current locale.

       This  function  is  not very appropriate for dealing with Unicode characters, because Unicode knows about
       three cases: upper, lower and title case.
