std::atomic<T>::load
| (since C++11) | ||
|
T load( std::memory_order order = std::memory_order_seq_cst ) const noexcept;
|
||
|
T load( std::memory_order order = std::memory_order_seq_cst ) const volatile noexcept;
|
||
Atomically loads and returns the current value of the atomic variable. Memory is affected according to the value of order.
order must be one of std::memory_order_relaxed, std::memory_order_consume, std::memory_order_acquire 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
| order | - | memory order constraints to enforce |
Return value
The current value of the atomic variable.
