#
The type wchar_Ā­t is a distinct type rather than a typedef to an existing integral type.
The token wchar_Ā­t is a keyword in this International Standard.
It does not appear as a macro or type name defined in any of <cstddef> ([cstddef.syn]), <cstdlib> ([cstdlib.syn]), or <cwchar> ([cwchar.syn]).
