towupper,

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

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