How to Use Class Library Methods

When using CAN communication driver functions in C#, call class library method other than calling the function directly.
The functions of CAN communication driver are called by calling the methods of class library.

The methods in the class library are defined as the original functions without the prefix,
so call them accordingly.

For example, when using CanInit function

Ret = can.Init ( ・・・・

For example, when using CntBusConnect function

Ret = can.BusConnect ( ・・・・
