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  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.

       towlower(3), towctrans(3), iswupper(3)

NOTES

       The behaviour 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.
