callback question

callback question

[micha]

I'm storing an ocaml object in a c++ class (the class calls methods of
the ocaml class). To do that I register the object as described for
callback functions in the manual and use it with caml_named_value.
It works perfect so it seems to be the right way. (?)
But does the gc ever remove the object (since it is registered as a
callback)?

In a class definition, is this the  correct way to get things cleaned
up:

class x = object
 val obj = native_pointer
 ...
 initializer
    Gc.finalise (fun _ -> delete native_pointer) self;
end;;

You don't need to post questions twice.

Why don't you call Gc.compact () and see if the object gets freed?

that was a mistake, I didn't saw my first post.

simply because I didn't know that.
