Detailed Description

This group contains the Event Manager implementation.

Function Documentation

rtems_status_code _Event_Seize	(	rtems_event_set	event_in,
		rtems_option	option_set,
		rtems_interval	ticks,
		rtems_event_set *	event_out,
		Thread_Control *	executing,
		Event_Control *	event,
		Thread_Wait_flags	wait_class,
		States_Control	block_state,
		ISR_lock_Context *	lock_context
	)

Seizes a set of events.

Parameters

event_in	is the input event set.
option_set	is the option set.
ticks	is the optional timeout in clock ticks.
event_out[out]	is the output event set.
executing[in,out]	is the executing thread.
event[in,out]	is the source event set.
wait_class	is the thread wait class of the source event set.
block_state	is the thread blocking state of the source event set.
lock_context[in,out]	is the lock context set up by _Thread_Get().

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_UNSATISFIED	The events of interest were not immediately available.
RTEMS_TIMEOUT	The events of interest were not available within the specified timeout interval.

rtems_status_code _Event_Surrender	(	Thread_Control *	the_thread,
		rtems_event_set	event_in,
		Event_Control *	event,
		Thread_Wait_flags	wait_class,
		ISR_lock_Context *	lock_context
	)

Surrenders a set of events.

Parameters

the_thread[in,out]	is the thread of the event set.
event_in	is the set of events to post.
event[in,out]	is the target event set.
wait_class	is the thread wait class of the target event set.
lock_context[in,out]	is the lock context set up by _Thread_Get().

Return values

RTEMS_SUCCESSFUL The requested operation was successful.
