COM:我可以在不调用 Release 的情况下调用 CoUninitialize 吗？

Question

我有个疑问。我初始化 COM，做 CoCreateInstance 并使用一些接口(interface)。我可以在不调用 Release 的情况下调用 CoUninitialize 吗？它会导致任何内存/资源泄漏吗？

CoUninitialize should be called on application shutdown, as the last call made to the COM library after the application hides its main windows and falls through its main message loop. If there are open conversations remaining, CoUninitialize starts a modal message loop and dispatches any pending messages from the containers or server for this COM application. By dispatching the messages, CoUninitialize ensures that the application does not quit before receiving all of its pending messages. Non-COM messages are discarded.

你应该只在关机时调用 CoUninitialize，到那时你是否有内存泄漏都没有关系。
