with RTEMS.TASKS;

package TMTEST is

--
--  Buffer Record similar to that used by RTEMS 3.2.1.  Using this
--  avoids changes to the test.
--

   type BUFFER is
      record
         FIELD1 : RTEMS.UNSIGNED32;   -- TEMPORARY UNTIL VARIABLE LENGTH
         FIELD2 : RTEMS.UNSIGNED32;
         FIELD3 : RTEMS.UNSIGNED32;
         FIELD4 : RTEMS.UNSIGNED32;
      end record;

--
--  The following is the ID of the message queue used for timing operations.
--

   QUEUE_ID : RTEMS.ID;

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

   END_TIME  : RTEMS.UNSIGNED32;

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

   procedure INIT (
      ARGUMENT : in     RTEMS.TASKS.ARGUMENT
   );
   pragma Convention (C, INIT);

--
--  TEST_INIT
--
--  DESCRIPTION:
--
--  This subprogram performs test initialization.  As each application
--  task is created and started, it will preempt this task and
--  perform a blocking MESSAGE_QUEUE_RECEIVE.  Once all of the 
--  initialization is completed, the timer is started and the first 
--  preemptive MESSAGE_QUEUE_URGENT is executed.
--

   procedure TEST_INIT (
      ARGUMENT : in     RTEMS.TASKS.ARGUMENT
   );
   pragma Convention (C, TEST_INIT);

--
--  HIGH_TASK
--
--  DESCRIPTION:
--
--  This RTEMS task is the highest priority task in the system.  
--  It performs a blocking blocking MESSAGE_QUEUE_RECEIVE.  It is
--  the last test task created and started.  Thus it is the last 
--  task to be enqueued waiting for a message and the last task
--  to receive the message.  Once it receives the message, it
--  stops the timer and reports the execution time for a
--  preemptive MESSAGE_QUEUE_URGENT.
--

   procedure HIGH_TASK (
      ARGUMENT : in     RTEMS.TASKS.ARGUMENT
   );
   pragma Convention (C, HIGH_TASK);

--
--  MIDDLE_TASKS
--
--  DESCRIPTION:
--
--  As each of these RTEMS tasks is created and started, it preempts
--  the initialization task and perform a blocking MESSAGE_QUEUE_RECEIVE.
--

   procedure MIDDLE_TASKS (
      ARGUMENT : in     RTEMS.TASKS.ARGUMENT
   );
   pragma Convention (C, MIDDLE_TASKS);
