[Boost-users] [newbie] creating a (complex?) C++ wrapper around a C function call...

I want to create a wrapper function

template <class foo>
op_pk_fd_set_class(packet *packet, int index,
                    foo &value, int simulated_bits);

around the following function... (in OPNET)

op_pk_fd_set(
     packet* pkptr,       // same as in wrapper
     int index,           // same as in wrapper
     int some_constant,   //OPC_TYPE_STRUCT
     void* value,
     int simulated_bits,  // same as in wrapper
     void* (*copy_proc)(void* obj_to_copy,int alloc_size),
     void (dealloc_proc*)(void *obj),
     int alloc_size);

I believe dealloc_proc can just be a function pointer to the destructor.
  I could very well be mistaken, but I believe that a normal constructor
takes only one parameter.  I also think alloc_size should be sizeof(foo).

I do not know how to obtain function pointers for constructor and
deconstructor member functions.  Any assistance I could get would be
appreciated.
