This is a simple demo program for the WNMP Barracuda plugin. The demo program contains two WNMP modules: coffee vending machine (coffee.c, coffee_impl.c) and test1 (test1.c, test1_impl.c). The stub file coffee_impl.c is not implemented and is left as an exercise for you. The MIB file for the coffee vending machine is in mib/COFFEE-POT-MIB.
Please see the WNMP documentation for more information.
