Elemento definito nell'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 );
Inizializza il default-costruito object oggetto atomico con il desired valore. La funzione non è atomica: l'accesso concorrente da un altro thread, anche attraverso un'operazione atomica, è una gara di dati.
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.

[modifica] Note

Questa funzione è prevista per la compatibilità con C. Se la compatibilità non è necessario, std::atomic possono essere inizializzate attraverso i loro costruttori non predefiniti.
Original:
This function is provided for compatibility with C. If the compatibility is not required, std::atomic may be initialized through their non-default constructors.
