std::atomic::store (3) Linux Manual Page

std::atomic<T>::store – std::atomic<T>::store

Synopsis

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

    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.

Parameters

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

Return value

(none)
