questions regarding shared_from_this

Question

I have a function which takes a shared_ptr. In some member function memfun of MyClass, I need to pass this

Answer 1

In addition with David Rodríguez - dribeas, shared pointer isn't recommended by google

It maintains reference count internally, so making it work correctly, InterlockedIncrement and InterlockedDecrement are used, these two functions are really slower than normal ++ and --.

You should check this object ownership truly need be shared with others, per my experience, shared pointer could be avoided in most cases.
