/***********************************************************************
**
** Name: dbmalloc1.c (OBSOLETE)
**
** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.
**
** Modification History:
** 14-May-97 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.
**
** 12-June-97 AGarcia Revert to return code 0 and 1, remove debug option (obsolete).
