TOWUPPER(3)						     Linux Programmer's Manual						       TOWUPPER(3)

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 upper-
       case.  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.
