问题描述
我有一个指向COM对象的指针(在C ++中).有没有一种方法可以获取指针指向的对象的当前引用计数?
I have a pointer to a COM object (in C++). Is there a way to get the current reference count of the object which the pointer is pointing to?
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.
