towlower — convert a wide character to lowercase
#include <wctype.h>
wint_t towlower( |
wint_t | wc); |
The 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.
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.
