TOWUPPER(R)         Linux Programmer's Manual         TOWUPPER(R)



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.

CONFORMING TO
       ISO/ANSI C, UNIX98

SEE ALSO
       towlower(r), towctrans(s), iswupper(r)

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.
