bool UltraLite_Connection_iface::RegisterForEvent( const ULValue & event_name, const ULValue & object_name, const ULValue & queue_name, bool register_not_unreg )
event_name system or user-defined event to register for
object_name object to which event applies (like table name)
queue_name NULL means default connection queue
register_not_unreg true to register, false to unregister
Register or unregister (a queue) to receive notifications of an event.
If no queue name is supplied, the default connection queue is implied, and created if required. Certain system events allow specification of an object name to which the event applies. For example, the TableModified event can specify the table name. Unlike SendNotification function, only the specific queue registered will receive notifications of the event - other queues with the same name on different connections will not (unless they are also explicit registered).
The predefined system events are:
True if the registration succeeded, false if the queue or event does not exist.
object_nameparameter specifies the table to monitor. A value of "*" means all tables in the database. This event has a parameter named 'table_name' whose value is the name of the modified table.
