std::atomic::load(3) | C++ Standard Libary | std::atomic::load(3) |
NAME¶
std::atomic::load - std::atomic::load
Synopsis¶
T load( std::memory_order order = std::memory_order_seq_cst )
const
noexcept; (since C++11)
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 (since C++20)
std::atomic<T>::is_always_lock_free is false.
Parameters¶
order - memory order constraints to enforce
Return value¶
The current value of the atomic variable.
