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.
