procedure Op (argv_Address : System.Address; N : Natural) is
   type Argv_Type is array (Positive) of chars_ptr;
   pragma Convention (C, Argv_Type);

   Argv : Argv_Type;
   for Argv'Address use argv_Address;

begin
   for I in 1 .. N loop
      Put_Line (Value (Argv (I)));  -- or whatever
   end loop;
end Op;

Is that what you had in mind?
