Defined in header <atomic>
(1) (since C++11)
template< class T >
T atomic_load( const std::atomic<T>* obj );
template< class T >
T atomic_load( const volatile std::atomic<T>* obj );
(2) (since C++11)
template< class T >

T atomic_load_explicit( const std::atomic<T>* obj,

                        std::memory_order order );
template< class T >

T atomic_load_explicit( const volatile std::atomic<T>* obj,

                        std::memory_order order );
1) Atomically obtains the value pointed to by obj as if by obj->load()
2) Atomically obtains the value pointed to by obj as if by obj->load(order)

Contents

[edit] Parameters

obj - pointer to the atomic object to modify
order - the memory sycnhronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_consume, std::memory_order_acquire and std::memory_order_seq_cst are permitted.

[edit] Return value

The value that is held by the atomic object pointed to by obj

[edit] Exceptions

noexcept specification:
