--  Fatal_Directive_Status
--
--  DESCRIPTION:
--
--  This subprogram checks if Status is equal to Desired.  If so, it 
--  returns immediately.  Otherwise, it prints the Message along with
--  the Status and Desired status and invokes the Fatal_Error_Occurred
--  directive.
--

   procedure Fatal_Directive_Status (
      Status  : in     RTEMS.Status_Codes;
      Desired : in     RTEMS.Status_Codes;
      Message : in     STRING
   );
   pragma Inline ( Fatal_Directive_Status );

--  Directive_Failed
--
--  DESCRIPTION:
--
--  This subprogram checks if Status is equal to Successful.  If so, it 
--  returns immediately.  Otherwise, it prints the Message along with
--  the Status and Desired status and invokes the Fatal_Error_Occurred
--

   procedure Directive_Failed (
      Status  : in     RTEMS.Status_Codes;
      Message : in     STRING
   );
   pragma Inline ( Directive_Failed );

--
--  Print_Time
--
--  DESCRIPTION:
--
--  This subprogram prints the Prefix string, following by the
--  time of day in Time_Buffer, followed by the Suffix.
--

   procedure Print_Time (
      Prefix      : in     STRING;
      Time_Buffer : in     RTEMS.Time_Of_Day;
      Suffix      : in     STRING
   );

--
--  Put_Dot
--
--  DESCRIPTION:
--
--  This subprogram prints a single character without a carriage return.
--

   procedure Put_Dot ( 
      Buffer : in     STRING
   );
   pragma Inline ( Put_Dot );

--
--  Pause
--
--  DESCRIPTION:
--
--  This subprogram is used to pause screen output in the Test Suites
--  until the user presses carriage return.
--

   procedure Pause;

--
--  Pause_And_Screen_Number
--
--  DESCRIPTION:
--
--  This subprogram is used to pause screen output  and print the current
--  number in the Test Suites until the user presses carriage return.
--

   procedure Pause_And_Screen_Number (
      SCREEN : in     RTEMS.Unsigned32
   );

--
--  Put_Name
--
--  DESCRIPTION:
--
--  This subprogram prints the RTEMS object Name.  If New_Line is TRUE, 
--  then a carriage return is printed after the Name.
--

   procedure Put_Name (
      Name     : in     RTEMS.Name;
      New_Line : in     Boolean
   );
 
--
--  Task_Number
--
--  DESCRIPTION:
--
--  This function returns the task index which the test should use
--  for TID.
--

   function Task_Number (
      TID : in     RTEMS.ID
   ) return RTEMS.Unsigned32;
   pragma Inline ( Task_Number );

--
--  Do_Nothing
--
--  DESCRIPTION:
--
--  This procedure is called when a test wishes to use a delay
--  loop and insure that the compiler does not optimize it away.
--

   procedure Do_Nothing;

--
--  Ticks_Per_Second is the number of RTEMS clock ticks which
--  occur each second.
--

   Ticks_Per_Second : RTEMS.Interval;

--
--  Milliseconds_Per_Tick is the number of milliseconds which
--  occur between each RTEMS clock tick.
