      8 ** Name: dbmalloc1.c (OBSOLETE)
      9 **
     10 ** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.
     11 **
     12 ** Modification History:
     13 ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
     14 **           The debug mode will print all of the printfs associated with this
     15 *test.
     16 **           The regress mode will be the default mode. Since the regress tool
     17 *limits
     18 **           the output to a one line status:PASS or FAIL,all of the printf
     19 *statements
     20 **           have been handled with an if (debug_mode) statement.
     21 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been
     22 *updated to
     23 **          recognize the return code from tha main program.
     24 **
     25 ** 12-June-97 AGarcia Revert to return code 0 and 1, remove debug option
     26 *(obsolete).
