Passing “this” to a function from within a constructor?

Question

Can I pass \"this\" to a function as a pointer, from within the class constructor, and use it to point at the object\'s members before the constructor returns?

Is it saf

Answer 1

As a side-note on the presented code, I would instead templatize the void*:

class Stuff
{
public:
    template 
    static void print_number(const T& t)
    {
        std::cout << t.number;
    }

    int number;

    Stuff(int number_)
    : number(number_)
    {
        print_number(*this);
    }
};

Then you'd get a compile error if the type of t doesn't have a number member.
