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.TASK_ARGUMENT

--
--  TEST_INIT
--
--  DESCRIPTION:
--
--  This subprogram performs test initialization.  After initialization
--  has been completed, the NO_WAIT case for MESSAGE_QUEUE_RECEIVE

   procedure TEST_INIT;

--
--  HIGH_TASK
--
--  DESCRIPTION:
--
--  This RTEMS task is the highest priority task in the system.  
--  It starts the timer and performs a blocking MESSAGE_QUEUE_RECEIVE.
--

   procedure HIGH_TASK (
      ARGUMENT : in     RTEMS.TASK_ARGUMENT
   );

--
--  MIDDLE_TASKS
--
--  DESCRIPTION:
--
--  These RTEMS tasks perform a blocking MESSAGE_QUEUE_RECEIVE.
--

   procedure MIDDLE_TASKS (
      ARGUMENT : in     RTEMS.TASK_ARGUMENT
   );

--
--  LOW_TASK
--
--  DESCRIPTION:
--
--  This RTEMS task stops the timer and reports the execution time 
--  of a blocking MESSAGE_QUEUE_RECEIVE.
--

   procedure LOW_TASK (
      ARGUMENT : in     RTEMS.TASK_ARGUMENT
   );
