-- This array contains the IDs of all RTEMS tasks created by this test.

TASK_ID : array ( RTEMS.UNSIGNED32
range 0 .. TIME_TEST_SUPPORT.OPERATION_COUNT ) of RTEMS.ID;
--
-- This variable is used to index through the TASK_ID array
-- so that events can be send to the next task.

-- The following variable is set to the execution time returned
-- by the timer.

-- DESCRIPTION:
--
-- This RTEMS task initializes the application.
--

ARGUMENT : in RTEMS.TASKS.ARGUMENT
);

--
-- TEST_INIT
--
-- DESCRIPTION:
--
-- This subprogram performs test initialization. Once initialization
-- has been completed, this task sets the TASK_COUNT to 0 and
-- starts the timer before performing a preemptive EVENT_SEND.

--
-- HIGH_TASK
--
-- DESCRIPTION:
--
-- This RTEMS task is highest priority task in the system.
-- Its first action is to perform a blocking EVENT_RECEIVE.
-- It is the last task to have its event set sent to it. Thus it
-- is the last task to be awakened by a preemptive EVENT_SEND.
-- After it preempts the last MIDDLE_TASKS, it stops the timer
-- and reports the execution time of preemptive EVENT_SEND.
--
procedure HIGH_TASK (
ARGUMENT : in RTEMS.TASKS.ARGUMENT
);
pragma Convention (C, HIGH_TASK);
--
-- MIDDLE_TASKS
--
-- DESCRIPTION:
--
-- These RTEMS tasks perform a blocking EVENT_RECEIVE. When
-- readied, each task will increment the TASK_COUNT and
-- perform a preemptive EVENT_SEND. TASK_COUNT is used to
-- index the TASK_ID array in such a way that incrementing
-- TASK_COUNT makes it index the ID of the next task to
-- send events to.

procedure MIDDLE_TASKS (
ARGUMENT : in RTEMS.TASKS.ARGUMENT
);
