Inquiry Intrinsic Function (Specific): Returns the INTEGER KIND that will hold an address. This is a specific function that has no generic function associated with it. It cannot be passed as an actual argument.
result = INT_PTR_KIND( )
The result type is default integer. The result is a scalar with the value equal to the value of the kind parameter of the integer data type that can represent an address on the targeted platform.
The result value is 4 on IA-32 target architecture; 8 on Intel® 64 architecture.
