DESCRIPTION

14       The  towlower()  function  is  the  wide-character  equivalent  of  the

16       ercase.  Characters  which do not have case are returned unchanged.  If
17       wc is WEOF, WEOF is returned.

RETURN VALUE

21       if wc is WEOF.

NOTES

30       The  behaviour  of  towlower()  depends on the LC_CTYPE category of the
31       current locale.
32
33       This function is not very appropriate for dealing with Unicode  charac‐
34       ters,  because  Unicode knows about three cases: upper, lower and title
35       case.
