/*********************************************************************** ** ** Name: dlltest.c ** ** Description: test dll functionality. ** ** Modification History: ** 14-May-97 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. ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been *updated to ** recognize the return code from tha main program. ** 12-June-97 Revert to return code 0 and 1.
