The event management framework allows a PU to request the PMC to call it notify callback whenever a qualifying event occurs. One can request to be notified for a specific node or any event related to a specific node. The two qualifying events will invoke the callback function for the following events:
- State change of the node for which callback is registered
- Zero users of the node for which callback is registered
- Error events for which callback is registered
If you are no longer interested in receiving notifications about events related to the node that the callback was previously requested, you can de-register it.
For more information on error events, see PLM Errors.
