I've added support for retrieving struct layout from C in a pull request:
It works in a very similar fashion to cstubs: you put your struct
declaration inside a functor
module Bindings(S : Cstubs_structs.STRUCT) =
let cell = structure "cell"
let payload = field cell int "payload"
let next = field cell (ptr cell) "next"
let () = seal cell
and then call Cstubs_structs.write_c to generate an ML module with
which to instantiate the functor.
The pull request has more details and some illustrative tests.
