Defined in header <atomic> template< class T > void atomic_init( std::atomic<T>* obj, T desired ); (since C++11) template< class T > void atomic_init( volatile std::atomic<T>* obj, T desired ); (since C++11) Initializes the default-constructed atomic object object with the value desired. The function is not atomic: concurrent access from another thread, even through an atomic operation, is a data race. If obj was not default-constructed, the be

Defined in header <atomic> atomic_flag(); (1) (since C++11) atomic_flag( const atomic_flag& ) = delete; (2) (since C++11) Constructs a new std::atomic_flag. 1) Trivial default constructor, initializes std::atomic_flag to unspecified state. 2) The copy constructor is deleted; std::atomic_flag is not copyable. In addition, std::atomic_flag can be value-initialized to clear state with the expression ATOMIC_FLAG_INIT. For an atomic_flag with static storage duration, t

Defined in header <atomic> class atomic_flag; (since C++11) std::atomic_flag is an atomic boolean type. Unlike all specializations of std::atomic, it is guaranteed to be lock-free. Unlike std::atomic<bool>, std::atomic_flag does not provide load or store operations. Member functions (constructor) constructs an atomic_flag (public member function) operator= the assignment operator (public member function) clear atomically sets flag to false (public me
