void store( T desired, std::memory_order order = std::memory_order_seq_cst ) const noexcept;		(since C++20)

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

order must be one of std::memory_order_relaxed, std::memory_order_release or std::memory_order_seq_cst. Otherwise the behavior is undefined.

Parameters

desired	-	the value to store into the referenced object
order	-	memory order constraints to enforce

Return value

(none)

stores a value into the object referenced by an atomic_ref object (public member function)
