Why not:

struct core_dummy_s {};
namespace prv {
class Dummy : public core_dummy_s
{
public:
....


In fact, why does prv::Dummy need to be a separate type from core_dummy_s?

And why are you creating a C++ wrapper around a C API of a C++ implementation?
Can't you remove the middle abstraction?

This isn't correct either: there is no object DummyClass at that location.
This will probably work, but isn't legal.
