You have two options for how the Broker will present events to Broker clients that are sharing the same client state. The default event ordering is called by-publisher and is described on By-Publisher Event Ordering. You can also opt to use no ordering, as described on Event Processing without Ordering.

The awGetDescriptorSharedEventOrdering method returns the current event processing order as either AW_SHARED_ORDER_NONE or AW_SHARED_ORDER_BY_PUBLISHER.

You can use the awSetDescriptorSharedEventOrdering method to specify the desired event processing order.
