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.
iswlower(3), towctrans(3), towupper(3)
