NAME¶

std::atomic::store - std::atomic::store

Synopsis¶

void store( T desired, std::memory_order order = (1) (since C++11)
std::memory_order_seq_cst ) noexcept;
void store( T desired, std::memory_order order =
std::memory_order_seq_cst ) volatile (2) (since C++11)
noexcept;

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

If order is one of std::memory_order_consume, std::memory_order_acquire and
std::memory_order_acq_rel, the behavior is undefined.

It is deprecated if std::atomic<T>::is_always_lock_free is false and (since C++20)
overload (2) participates in overload resolution.

Parameters¶

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

Return value¶

(none)
