Defined in header <atomic>
template< class T >
void atomic_store( std::atomic<T>* obj, T desr );
 (1) (since C++11)
template< class T >
void atomic_store( volatile std::atomic<T>* obj, T desr );
 (2) (since C++11)
template< class T >

void atomic_store_explicit( std::atomic<T>* obj, T desr,

                            std::memory_order order);
 (3) (since C++11)
template< class T >

void atomic_store_explicit( volatile std::atomic<T>* obj, T desr,

                            std::memory_order order);
 (4) (since C++11)

1-2) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr)

3-4) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr, order)

Contents

Parameters

desr - the value to store in the atomic object
order - the memory synchronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_release and std::memory_order_seq_cst are permitted.

Return value

none.
