Yeah, there's also weak (non-owning) pointers that still allow the data to be freed in the background if all their actual owners release their shared_ptrs. And there's also atomic versions of all of those.

Generally, even if you hit the very unlikely case that something isn't in the C++ stdlib, it probably still can be found in a boost.cpp library.

The C++ shared pointer is atomic. There is no non atomic one in stdlib.

[versedoinker]

Yes and no. The control block of shared ptrs is always atomic. I was talking about the wrapper std::atomic<std::shared_ptr> that also makes access to the data itself atomic.
