Hi,

I'm trying to bind the following struct:

typedef struct mpc_ast_t {
  char *tag;
  char *contents;
  mpc_state_t state;
  int children_num;
  struct mpc_ast_t** children;
} mpc_ast_t;

I have this:

   type ASTs is
   record
      Tag                : C.Strings.chars_ptr;
      Contents           : C.Strings.chars_ptr;
      State              : States;
      Number_Of_Children : C.int;
      Children           : System.Address; --  Pointer to a pointer to an array of ASTs.
   end record with
     Convention => C;

Children needs to be accessed in code as a pointer to a pointer to an array of ASTs.

How do I best bind this thing? It's likely going to have to be converted from Address to a particular type using Unchecked_Conversion most likely.

Thanks,
Luke.
