std::atomic<std::shared_ptr<T>>

std::atomic is a C++ class template that provides atomic operations on its template parameter. In this case, the template parameter is std::shared_ptr<T>, which is a type of smart pointer that manages a reference-counted object.

The std::atomic<std::shared_ptr<T>> class template ensures that operations on the shared_ptr object are atomic, meaning that they are indivisible and cannot be interrupted by other threads. This prevents race conditions and ensures that the shared_ptr object is always in a consistent state.

The atomic operations provided by std::atomic<std::shared_ptr<T>> include load, store, and exchange. These operations allow multiple threads to access and modify the shared_ptr object without causing data races or other synchronization issues.

Overall, std::atomic<std::shared_ptr<T>> is a powerful tool for managing shared resources in a multithreaded environment, providing a safe and efficient way to share data between threads.
