C array to ada record interface

[fjloma@andaluciajunta.es (Francisco Javier Loma Daza)]

It may be a FAQ, but I had not succeed to find some info so ...

I have a C struct like that

struct
{
   int a,b,c:
   int len;
   struct b* arr;
} A;

And I would love to interface in Ada with a record with a discriminant

type B_array(len: Positive) is record
    arr: array of B(1..len);
end record;

type A(len: Positive) is
   a,b,c: Integer;
   arr:   A(len);
end record;


What representation clauses and interfacing pragmas I need to use? Is
there a repository of examples about C interfacing?


Thanks in advance
