Graph::RegisterEventHandle
Subscribes to interested events. Currently, the host-device disconnection event is supported. When disconnection occurs, the user can receive this event and handle the disconnection logic (for example, waiting for stopping the main program) in the registered callback function. This API is defined in graph.h.
