std::call_once may also reach the same goal. Use both static community variables of C++eleven or std::call_once in place of creating your own personal double-checked locking for initialization.

Shared_ptr // A type that matches Pointer, has duplicate, and matches the Life span profile standards for just a shared operator kind; see intelligent ideas

In the event you publish/disable possibly from the copy constructor or the duplicate assignment operator, you almost certainly have to do the same for the other: If 1 does “Distinctive” perform, most likely so must another since the two features ought to have similar consequences.
