You should not be messing with mixed-language programming until you are no
longer new to Ada. Much of your problem comes from the fact that you don't
understand packages yet.
When you do get to mixed-language programming, you should never use any types in
your code that interfaces with C that are not declared in Interfaces.C and its
children, or that are declared to be Convention C.
