Broadcasting

Broadcasting is a communication channel used for sending one to many type of messages.

Implementation using User Events

The transport mechanism for broadcast messages is based on User Events with a fixed data type. The creation of the broadcast User Event reference and event registration is managed by framework methods. To register for broadcasts from a process, use the Register for Broadcast Events.vi. There is also a method available to recursively register for all processes within an Application called Register for Broadcast Events Recursively.vi.

To receive broadcasts, an event structure should be used as shown above.
