The
towlower
()
function converts an upper-case letter to the corresponding lower-case
letter.
Although the
towlower
()
function uses the current locale, the
towlower_l
()
function may be passed a locale directly. See
xlocale(3) for more information.
If the argument is an upper-case letter, the
towlower
() function returns the corresponding
lower-case letter if there is one; otherwise, the argument is returned
unchanged.
