1.11 +** Name: dbmalloc1.c
1.12 +**
1.13 +** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.
1.14 +**
1.15 +** Modification History:
1.16 +**
1.17 +** 19-May-97 AGarcia - separate the four join tests into different unit test modules.
1.18 +** AGarcia- Converted the test to accomodate the debug_mode flag.
1.19 +** The debug mode will print all of the printfs associated with this test.
1.20 +** The regress mode will be the default mode. Since the regress tool limits
1.21 +** the output to a one line status:PASS or FAIL,all of the printf statements
1.22 +** have been handled with an if (debug_mode) statement.
