To make it more easy to implement the only thing that is missing in ctypes now is `val ptr_to_raw_address : unit ptr -> int64`. In my example below I bypassed that by directly using the "ctypes_dlsym" stub.

It looks fine to me.  I've added the missing function here:

Shouldn't this be

   value mlapp_str_int (value fun_ptr, value str)

?
