How to use a object whose copy constructor and copy assignment is private?

Question

In reading TCPL, I got a problem, as the title refered, and then \'private\' class is:

class Unique_handle {
private:
    Unique_handle& operato         


        

Answer 1

I have googled my question, and find a way to construct such a object:

static Unique_handle* instance() { return new Unique_handle(); }

but it seems wrong, then how can I define such a object outside?

Anyway, thank you for all of your concern.
