* * 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 .
