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)
