From cppreference.com
Defined in header <experimental/atomic>
template < class T >
class atomic_shared_ptr;
(concurrency TS)

The class template atomic_shared_ptr provides thread-safe atomic pointer operations over a std::shared_ptr. It provides a better alternative to the non-member shared_ptr atomic access functions.
