Defined in header <atomic>
template< class T >
void atomic_init( std::atomic<T>* obj, T desired );
template< class T >
void atomic_init( volatile std::atomic<T>* obj, T desired );
Initialisiert die default-gebaut atomaren Objekt object mit dem Wert desired. Die Funktion ist nicht atomic: den gleichzeitigen Zugriff von einem anderen Thread, auch durch eine atomare Operation, ist ein Daten-Rennen .
Original:
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.
