     10 ** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.
     11 **
     12 ** Modification History:
     13 **
     14 ** 19-May-97 AGarcia - separate the four join tests into different unit test
     15 *modules.
     16 **           AGarcia- Converted the test to accomodate the debug_mode flag.
     17 **           The debug mode will print all of the printfs associated with this
     18 *test.
     19 **           The regress mode will be the default mode. Since the regress tool
     20 *limits
     21 **           the output to a one line status:PASS or FAIL,all of the printf
     22 *statements
     23 **           have been handled with an if (debug_mode) statement.
     24 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been
     25 *updated to
     26 **          recognize the return code from tha main program.
