NAME

std::atomic_flag::clear - std::atomic_flag::clear

Synopsis

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

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

Parameters

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