DESCRIPTION
The
R 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
R towupper ()
function returns the uppercase equivalent of wc,
or WEOF if wc is WEOF.
CONFORMING TO
C99.
NOTES
The behavior of
R 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.
