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).
| order | - | the memory synchronization ordering for this operation (cannot be std::memory_order_consume, std::memory_order_acquire, or std::memory_order_acq_rel) |
atomically sets the flag to true and obtains its previous value (public member function) |
|
|
(C++11)(C++11) | atomically sets the value of the flag to false (function) |
|
(C++11) | defines memory ordering constraints for the given atomic operation (enum) |
