Ada modular types provide bitwise operations.
So if you need bitwise operations on Integers or C.Int
you should change their view to modular type and then
do bitwise operations.
Something like this:
CIM is new Ada.Unchecked_Conversion ( Interfaces.C.Int,
Interfaces.C.Unsigned);
CMI is new Ada.Unchecked_Conversion ( Interfaces.C.Unsigned,
Interfaces.C.Int);
...
a : Interfaces.C.Int;
b : Interfaces.C.Int;
c : Interfaces.C.Int;
c := CMI ( CIM(a) or CIM (b) );
That's all you need.
