Subscribing to Events

Uniqueness of Subscriptions

Your application may subscribe to an event by calling the awNewSubscription function. The following example contains an excerpt from the subscribe1.c sample application that shows the use of the awNewSubscription function. The function accepts these parameters:

A BrokerClient handle.

An event type name.

An event filter string or NULL if event filtering is not desired. Filters are described in Managing Event Types.

BrokerClient c;

/* Make a subscription */
err = awNewSubscription(c, "Sample::SimpleEvent", NULL);
if (err != AW_NO_ERROR) {
printf("Error on create subscription\n%s\n", awErrorToString(err));
return 0;
}
