推荐答案
调用 IUnknown :: AddRef ，然后立即 IUnknown :: Release .后者返回的值是未完成引用的当前计数.请注意，该值不一定是准确的，仅是参考信息.
Call IUnknown::AddRef and then immediately IUnknown::Release. The value returned by the latter is current count of outstanding references. Note that the value does not have to be accurate, it is informational only.
