std::atomic_store
STD：：原子[医]存储，STD：：原子[医]商店[医]显式
| Defined in header | | |
|---|---|---|
| | (1) | (since C++11) |
| template< class T > void atomic_store( std::atomic<T>* obj, T desr | | |
| template< class T > void atomic_store( volatile std::atomic<T>* obj, T desr | | |
| | (2) | (since C++11) |
| template< class T > void atomic_store_explicit( std::atomic<T>* obj, T desr, std::memory_order order | | |
| template< class T > void atomic_store_explicit( volatile std::atomic<T>* obj, T desr, std::memory_order order | |
1%29原子替换obj有价值的desr好像obj->store(desr)
2%29原子替换obj有价值的desr好像obj->store(desr, order)
参数
| obj | - | pointer to the atomic object to modify |
|---|---|---|
| desr | - | the value to store in the atomic object |
| order | - | the memory synchronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_release and std::memory_order_seq_cst are permitted. |

| store | atomically replaces the value of the atomic object with a non-atomic argument (public member function of std::atomic) |
|---|---|
| atomic_loadatomic_load_explicit (C++11)(C++11) | atomically obtains the value stored in an atomic object (function template) |
| memory_order (C++11) | defines memory ordering constraints for the given atomic operation (typedef) |
| std::atomic_store(std::shared_ptr) std::atomic_store_explicit(std::shared_ptr) | specializes atomic operations for std::shared_ptr (function template) |
