Question

Is there a way to know that my object is alive other than declaring a static private member in class and increment it in constructor, decrement it in destructor. Thanks in advance.

You can also do it non-intrusively to your class with STL using shared_ptr/weak_ptr.

stl::shared_ptr<YourClass> p = stl::make_shared(...); // holds a strong reference to your type
stl::weak_ptr<YourClass> wp(p);  

cout << wp.use_count(); // "1"

p.reset();

cout << wp.use_count(); // "0"
