Defined in header <atomic>
void clear( std::memory_order order =
                std::memory_order_seq_cst ) volatile noexcept;
(1) (since C++11)
void clear( std::memory_order order =
                std::memory_order_seq_cst ) noexcept;
(2) (since C++11)

Atomically changes the state of a std::atomic_flag to clear (false).

If order is one of std::memory_order_consume, std::memory_order_acquire and std::memory_order_acq_rel, the behavior is undefined.

[edit] Parameters

order - the memory synchronization ordering
