wint_t, WEOF - integer type capable of storing any wchar_t of WEOF

wint_t  is  a  type used in functions that work with wide characters.  It is capable of storing any valid
       wchar_t or WEOF.  It is an integer type.

       WEOF is used by wide-character functions to indicate the end of an input file or an error.  It is of type
       wint_t.
