lower case letter conversion (wide character version)
Standard C Library (libc, -lc)
#include
<wctype.h>
wint_t
towlower(wint_t wc);

wint_t
towlower_l(wint_t wc,
locale_t loc);
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.
