__EventQueueOverflowEvent class

The __EventQueueOverflowEvent system class reports when an event is dropped as a result of delivery queue overflow.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.


class __EventQueueOverflowEvent : __EventDroppedEvent
  uint32              CurrentQueueSize;
  object              Event;
  __EventConsumer REF IntendedConsumer;
  uint8               SECURITY_DESCRIPTOR[];
  uint64              TIME_CREATED;
