Inoltre, può essere std::atomic_flag valore inizializzato per cancellare lo stato con il ATOMIC_FLAG_INIT espressione. Per un atomic_flag con durata di memorizzazione static, questo garantisce che i valori di questo flag è noto prima che i costruttori sono funzionare per oggetti statici.
Original:
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, this guarantees that the values of this flag is known before any constructors are run for static objects.
