Detailed Description

IDHGenericEvent An IDH will often have to post events from at interrupt time. Since memory allocation cannot occur from the interrupt handler, the IDH can preallocate storage needed for handling the event by creating some IDHGenericEvent items. Subsequently, when an event is generated, the type of event (specified in the IDHEventHeader) will dictate how the IDHGenericEvent should be interpretted.

IMPORTANT NOTE : This means that a specific event structure can NEVER be greater than the size of the generic one.
