**
** Name: dbmalloc1.c
**
** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.
**
** Modification History:
**
** 19-May-97 AGarcia - separate the four join tests into different unit test
*modules.
**          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.
