Event Manager Initialization.

Event Manager

This routine performs the initialization necessary for this manager.

• INTERRUPT LATENCY:
  • single case

References _MPCI_Register_packet_processor().

_Event_sets_Clear()

RTEMS_INLINE_ROUTINE rtems_event_set _Event_sets_Clear	(	rtems_event_set	the_event_set,
		rtems_event_set	the_mask
	)

Removes the events in mask from the event_set passed in.

This function removes the events in mask from the event_set passed in. The result is returned to the user in event_set.

_Event_sets_Get()

RTEMS_INLINE_ROUTINE rtems_event_set _Event_sets_Get	(	rtems_event_set	the_event_set,
		rtems_event_set	the_event_condition
	)

Returns the events in event_condition that are set in event_set.

This function returns the events in event_condition which are set in event_set.

_Event_sets_Is_empty()

RTEMS_INLINE_ROUTINE bool _Event_sets_Is_empty

(

rtems_event_set

the_event_set

)

Checks if on events are posted in the event_set.

This function returns TRUE if on events are posted in the event_set, and FALSE otherwise.

Referenced by rtems_event_receive(), and rtems_event_system_receive().

_Event_sets_Post()

RTEMS_INLINE_ROUTINE void _Event_sets_Post	(	rtems_event_set	the_new_events,
		rtems_event_set *	the_event_set
	)

Posts the given new_events into the event_set passed in.

This routine posts the given new_events into the event_set passed in. The result is returned to the user in event_set.
