std::atomic<T>::store

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

Atomically replaces the current value 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.

The volatile-qualified version is deprecated if std::atomic<T>::is_always_lock_free is false.

(since C++20)

Parameters

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

Return value

(none).
