std::atomic_ref<T>::store
From cppreference.com
< cpp | atomic | atomic ref
void store( value_type desired, std::memory_order order = |
(constexpr since C++26) | |
Atomically replaces the current value of the referenced object with desired. Memory is affected according to the value of order.
This overload participates in overload resolution only if std::is_const_v<T> is false.
If order is not std::memory_order_relaxed, std::memory_order_release or std::memory_order_seq_cst, the behavior is undefined.
[edit] Parameters
desired | - | the value to store into the referenced object |
order | - | memory order constraints to enforce |
