I wint_t towlower(wint_t wc );
DESCRIPTION
The
R towlower ()
function is the wide-character equivalent of the
tolower(3)
function.
If
wc is a wide character, it is converted to
lowercase.
Characters which do not have case are returned unchanged.
If
wc is WEOF, WEOF is returned.
RETURN VALUE
The
R towlower ()
function returns the lowercase equivalent of wc,
or WEOF if wc is WEOF.
CONFORMING TO
C99.
NOTES
The behavior of
R towlower ()
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.
