Hi all,

I'm wrapping some C code that requires me to define a struct in Ocaml
like this:

    type xt = { f : xt -> a }

and then pass the struct to C which stores it, and later the C needs
to find function f, call it from C, passing it the Ocaml xt struct.

Anyone have any clues on how to do this? I have most of the rest of
the C wrapper sorted out,  its just this thats causing me any difficulty.

Cheers,
Erik
