  推荐答案

  我认为 这个页面 很好地涵盖了它.调用 RegisterInterfaceInGlobal 将您的 COM 接口放入 GIT，将其 cookie 传递给您的其他线程，然后可以使用该 cookie 调用 GetInterfaceFromGlobal 以获取原始接口.

  I think this page covers it rather well. Call RegisterInterfaceInGlobal to put your COM interface in the GIT, pass its cookie to your other threads, which can then call GetInterfaceFromGlobal using that cookie to get the original interface.

  请注意，每个线程都必须调用 CoCreateInstance(CLSID_StdGlobalInterfaceTable......但别担心，它们都会获得一个指向同一 GIT 实例的接口指针.

  Note that each thread has to call CoCreateInstance(CLSID_StdGlobalInterfaceTable... but don't worry, they all get an interface pointer to the same instance of the GIT.
