# std::atomic_ref<T>::store

From cppreference.com
< cpp‎ | atomic‎ | atomic ref

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)

operator= | stores a value into the object referenced by an `atomic_ref` object (public member function)
