std::atomic<T>::store - cppreference.com

From cppreference.com

`void store( T desired, std::memory_order order = std::memory_order_seq_cst ) noexcept;`	(1)	(since C++11)
`void store( T desired, std::memory_order order = std::memory_order_seq_cst ) volatile noexcept;`	(2)	(since C++11)

Atomically replaces the current value with desired. Memory is affected according to the value of order.

If order is one of std::memory_order_consume, std::memory_order_acquire and std::memory_order_acq_rel, the behavior is undefined.

It is deprecated if std::atomic<T>::is_always_lock_free is false and overload (2) participates in overload resolution.

(since C++20)

desired	-	the value to store into the atomic variable
order	-	memory order constraints to enforce

(none)
