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 ) |
noexcept
specification: noexcept
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 (typedef) |
