40** Name: dlltest.c
41**
42** Description: test dll functionality.
43**
44** Modification History:
45** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
46** The debug mode will print all of the printfs associated with this test.
47** The regress mode will be the default mode. Since the regress tool limits
48** the output to a one line status:PASS or FAIL,all of the printf statements
49** have been handled with an if (debug_mode) statement.
50** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
51** recognize the return code from tha main program.
52** 12-June-97 Revert to return code 0 and 1.
