void store( T desired, std::memory_order order =
std::memory_order_seq_cst ) noexcept;
(1)
(since C++11)
std::memory_order_seq_cst ) noexcept;
void store( T desired, std::memory_order order =
std::memory_order_seq_cst ) volatile noexcept;
(2)
(since C++11)
std::memory_order_seq_cst ) volatile 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 overload (2) participates in overload resolution.
(since C++20)[edit] Parameters
desired
-
the value to store into the atomic variable
order
-
memory order constraints to enforce
[edit] Return value
(none)
