Registering Events
Events do not have callbacks because they cannot be invoked from ThingWorx platform as a request to the edge device running your application. For your application to report events back to ThingWorx platform, use the twApi_RegisterEvent function to register the events. For more information about the function, refer to the Doxygen documentation that accompanies the C SDK.
