该操作是原子读取操作。 第一个版本根据命令对内存进行访问memory_order_seq_cst,第二个版本根据内存访问内存访问order。order必须是一个memory_order_relaxed,memory_order_consume,memory_order_acquire或memory_order_seq_cst。否则,行为是不确定的。 这是为所有原子对象类型定义的通用函数A。该参数是指向易失性原子...
C atomic_load_explicit(constvolatileA*obj,memory_orderorder); (2)(C11 起) 原子地加载并返回obj所指向的原子对象的当前值。该操作是原子读操作。 第一版本按照memory_order_seq_cst排序内存访问,第二版本根按照order排序内存访问。order必须是memory_order_relaxed、memory_order_consume、memory_order_acquire或...
This shall be one of the following values of theenumtypememory_order: memory_order_seq_cst memory_order_consume memory_order_acquire memory_order_relaxed Return value The contained value. Tis the type of the contained value (atomic's template parameter). ...
order must be one of memory_order_relaxed, memory_order_consume, memory_order_acquire or memory_order_seq_cst. Otherwise the behavior is undefined. This is a generic function defined for all atomic object types A. The argument is pointer to a volatile atomic type to accept addresses of ...

obj - 指向要加载的原子对象的指针 order - 此操作所用的内存同步顺序:只容许 std::memory_order_relaxed、 std::memory_order_consume、 std::memory_order_acquire 和std::memory_order_seq_cst。 返回值obj 所指向的原子对象所保有的值。 参阅load 原子地获得原子对象的值 (std::atomic<T> 的公开...
C atomic_load_explicit( const volatile A* obj, memory_order order ); (2) (C11 起) 原子地加载并返回 obj 所指向的原子对象的当前值。该操作是原子读操作。 第一版本按照 memory_order_seq_cst 排序内存访问,第二版本根按照 order 排序内存访问。 order 必须是 memory_order_relaxed、 memory_order_co...
2%29原子地获得obj好像obj->load(order) 参数 obj - pointer to the atomic object to modify order - the memory synchronization 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. ...
The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to order. order must be one of memory_order_relaxed, memory_order_consume, memory_order_acquire or memory_order_seq_cst. Otherwise the behavior is undefined. ...
