The client of the binding is going to have to do some low level work to use the binding, which is a bit nasty. However exposing the structures and letting them poke about in them feels too dangerous. And a key struct also uses bitfield :) In C++ you’d provide a constructor, and some accessor and mutator methods, and make the actual data private. In Ocaml, it feels more natural in these cases where functional operations are favoured to make the structure opaque, and if necessary for construction, write some methods in C, and then provide binding to them. — john skaller [email protected] http://felix-lang.org _______________________________________________ Ctypes mailing list [email protected] http://lists.ocaml.org/listinfo/ctypes
