I did a lot of C interfacing and there are quite a few option open. Usualy
you need two parameters one for the array one for the size.
A very interesting hint - if you declare the following type inside a
procedure:
type C_Array is array 0 .. Number - 1 of Interfaces.C.int;
then Number does not need to a constant. And of course the other way around
as well:
type Ada_Array is array 1 .. Number of Integer;
