michael@0 7 **
michael@0 8 ** Name: dlltest.c
michael@0 9 **
michael@0 10 ** Description: test dll functionality.
michael@0 11 **
michael@0 12 ** Modification History:
michael@0 13 ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
michael@0 14 ** The debug mode will print all of the printfs associated with this test.
michael@0 15 ** The regress mode will be the default mode. Since the regress tool limits
michael@0 16 ** the output to a one line status:PASS or FAIL,all of the printf statements
michael@0 17 ** have been handled with an if (debug_mode) statement.
michael@0 18 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
michael@0 19 ** recognize the return code from tha main program.
michael@0 20 ** 12-June-97 Revert to return code 0 and 1.
