NAME
       towlower - convert a wide character to lowercase

SYNOPSIS
       #include <wctype.h>

       wint_t towlower(wint_t wc);

DESCRIPTION
       The  towlower  function is the wide-character equivalent of the tolower
       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 towlower function returns the lowercase equivalent of wc,  or  WEOF
       if wc is WEOF.

NOTES
       The  behaviour of towlower depends on the LC_CTYPE category of the cur-
       rent locale.

       This function is not very appropriate for dealing with Unicode  charac-
       ters,  because  Unicode knows about three cases: upper, lower and title
       case.
