** Name: joinuk.c
**
** Description: Join kernel - user
**
** Modification History:
** 
** 19-May-97 AGarcia - separate the four join tests into different unit test modules.
**			 AGarcia- Converted the test to accomodate the debug_mode flag.
**	         The debug mode will print all of the printfs associated with this test.
**			 The regress mode will be the default mode. Since the regress tool limits
**           the output to a one line status:PASS or FAIL,all of the printf statements
**			 have been handled with an if (debug_mode) statement.
** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
**			recognize the return code from tha main program.
