ibnotify is part of the IEEE 488 API. NI-DAQ has it's own API with it's own event functions (Config_DAQ_Event_Message, etc.). The Lab-PC board is a pretty old DAQ board though, and I'm not sure that these functions are available in the old version of NI-DAQ you are using.
The flexmotion API is not event-driven so there is no equivalent to ibnotify. You would have to poll the status of the operations that are running (there are status functions for this). In CVI you could do this in a timer CB or another thread for motion.
