std::atomic_flag
 
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).

Parameters

order - the memory synchronization ordering for this operation (cannot be std::memory_order_consume, std::memory_order_acquire, or std::memory_order_acq_rel)
