Overview
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.
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 argument is returned unchanged.
