EventMask Objects
Introduction
The EventMask determines which event types will be sent from the controller to the Notify object. By setting bits in the EventMask, specific events can be sent to the Notify object when they occur or by clearing specific bits, the events can be ignored. By default, no Events will occur until the EventMask is set.
The Event, EventMgr, and Notify objects are used with the EventMask to handle controller events.
Data Types
| MPIEventMask | An array of unsigned longs |
Macros
