       wint_t towupper (wint_t wc);

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       The towupper function returns the uppercase equivalent of wc,  or  WEOF
       if wc is WEOF.

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

NOTES    [Toc]    [Back]

       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.
