_InterlockedExchange为 Win32 Windows SDKInterlockedExchange函数提供编译器内部支持。 _InterlockedExchange存在几种变体,这些变体根据其涉及的数据类型和是否使用特定于处理器获取或发布语义而有所不同。 当_InterlockedExchange函数对 32 位整数值操作时,_InterlockedExchange8对 8 位整数值操作,_InterlockedExchange16对 ...
Interlocked.Decrement(ref value) 数值减一(原子性操作) Interlocked.Exchange(ref value1, value2) 交换:把值2赋给值1;返回新值 Interlocked.CompareExchange(ref value1, value2, value3) 实现比较和交换两种功能:值1和值3比较,如果相同,把值2给值1,不相同则不作任何操作;返回原值(多用于判断条件)(示例3中...

InterlockedCompareExchange msdn states that InterlockedCompareExchange has performance penalties due to "memory fences". For performance gains modern CPUs often execute instructions out of order to make maximum use of the available silicon (including memory read/writes). Because the hardware enforces ...
