1.10 +**
1.11 +** Name: dlltest.c
1.12 +**
1.13 +** Description: test dll functionality.
1.14 +**
1.15 +** Modification History:
1.16 +** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
1.17 +** The debug mode will print all of the printfs associated with this test.
1.18 +** The regress mode will be the default mode. Since the regress tool limits
1.19 +** the output to a one line status:PASS or FAIL,all of the printf statements
1.20 +** have been handled with an if (debug_mode) statement.
1.21 +** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
1.22 +** recognize the return code from tha main program.
1.23 +** 12-June-97 Revert to return code 0 and 1.
