     8 ** Name: joinuk.c

     9 **

    10 ** Description: Join kernel - user

    11 **

    12 ** Modification History:

    13 **

    14 ** 19-May-97 AGarcia - separate the four join tests into different unit test modules.

    15 **			 AGarcia- Converted the test to accomodate the debug_mode flag.

    16 **	         The debug mode will print all of the printfs associated with this test.

    17 **			 The regress mode will be the default mode. Since the regress tool limits

    18 **           the output to a one line status:PASS or FAIL,all of the printf statements

    19 **			 have been handled with an if (debug_mode) statement.

    20 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to

    21 **			recognize the return code from tha main program.
