std::atomic_store, std::atomic_store_explicit

Defined in header <atomic>
(1) (since C++11)
template< class T >
void atomic_store( std::atomic<T>* obj, T desr );
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);
template< class T >
void atomic_store_explicit( volatile std::atomic<T>* obj, T desr, 
                            std::memory_order order);
1) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr)
2) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr, order)

Parameters

obj - pointer to the atomic object to modify
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.

Exceptions

noexcept specification:
