DESCRIPTION
The towupper() function converts a lower-case letter to the corresponding
upper-case letter.

towupper_l() function may be passed a locale directly. See xlocale(3) for
more information.
RETURN VALUES
If the argument is a lower-case letter, the towupper() function returns
the corresponding upper-case letter if there is one; otherwise, the argu-
ment is returned unchanged.
