shared_from_this called from constructor

Question

I have to register an object in a container upon its creation. Without smart pointers I\'d use something like this:

a_class::a_class()
{
    register_somewhere(t         


        

Answer 1

For this purpose, I wrote my own drop-in replacement for shared_ptr, weak_ptr and enable_shared_from_this. You can check it out at Sourceforge.

It allows call of shared_from_this() in constructor and destructor without helper functions without space overhead compared to the standard enable_shared_from_this.

Note: creating shared_ptr's in dtors is only allowed as long as they are created only temporarily. That is, they are being destroyed before the dtor returns.
