The atomic library provides components for fine-grained atomic operations allowing for lockless concurrent programming. Each atomic operation is indivisible with regards to any other atomic operation that involves the same object. Atomic objects are the only C++ objects free of data races; that is, if one thread writes to an atomic while another thread reads from it, the behavior is well-defined.
