Além disso, pode ser std::atomic_flag valor inicializado para limpar estado com o ATOMIC_FLAG_INIT expressão. Para uma atomic_flag com duração de armazenagem estática, o que garante que os valores desta bandeira é conhecida antes de qualquer construtores são executados para objetos estáticos.
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.
