NAME¶

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

The volatile-qualified version is deprecated if (since C++20)
std::atomic<T>::is_always_lock_free is false.

Parameters¶

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

Return value¶

(none)
