TOWLOWER(3)						     Linux Programmer's Manual						       TOWLOWER(3)

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(3) function.  If wc is a wide character, it is converted to lower-
       case.  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.

CONFORMING TO
       C99.

NOTES
       The behavior of 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.
