This method takes no parameters.
Return S_OK or an error code.
In general, this call can occur on any thread, and the caller may be holding critical sections. Therefore, this method should not do anything that could cause a deadlock. Instead, the method should set an event or post a message to another thread, and the other thread should take any required actions.
