   8 ** Name: dbmalloc1.c

  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 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.
