有没有办法查询_com_ptr_t对象的当前引用计数？
[英]Is there a way to query the current reference count of a _com_ptr_t object?
问题描述
I'm having some issues (crashing) with a COM object that is wrapped in a _com_ptr_t template object. 
我遇到了一个包装在_com_ptr_t模板对象中的COM对象的问题（崩溃）。 I need to interrogate the object to see what the reference count is, because I'm pretty sure that the object is getting destroyed prematurely. 我需要询问对象以查看引用计数是什么，因为我非常确定该对象会被过早破坏。
It would be even better if I could somehow hook into the AddRef() and Release() functions, but I can't seem to find where these are beyond the ones located in the _com_ptr_t class. 如果我能以某种方式挂接到AddRef()和Release()函数，那会更好，但是我似乎找不到除_com_ptr_t类中的函数之外的其他函数。 Ideas? 有想法吗？

_com_ptr_t wraps an IUnknown instance, but hides the return of AddRef and Release which would be the current reference count. _com_ptr_t包装了一个IUnknown实例，但隐藏了AddRef和Release的返回值，它们将是当前引用计数。 GetInterfacePtr should "lift the fog". GetInterfacePtr应该“解除迷雾”。
