Internal notes:
TimeOut, DriverBufferSize : it is possible that these parameters can be moved to another function like TE_USB_FX2_SetTimeOut and
TE_USB_FX2_SetDriverBufferSize or erased (internally fixed) if Trenz Electronic decides in this direction.
The instantiation of driver buffer happens in TE_USB_FX2_Open(): the user must specify TimeOut and DriverBufferSize.
A future extension is the possibility to set TimeOut = 1000 (1 ms) and DriverBufferSize = 131,072 if the respective value passed to the function is 0.

A Note on the Header File TE_USB_FX2_CyAPI.h

Two different header files exist.
One is used for the creation of TE_USB_FX2_CyAPI.dll DLL.
Another header file (with the same name) is exported for the creation of application programs that use TE_USB_FX2_CyAPI.dll DLL.
The latter has some additional lines with regard to the former. This happens to solve some problems with the include files in applications.
The lines of difference are the followings (added to TE_USB_FX2_CyAPI.h used for applications).
#pragma once
//#include <WinDef.h> NO, it fails at 32 bit
#include <windows.h>
#include "CyAPI.h"
typedef unsigned char byte;
Internal note: The file to use is in C:\Project3264bit\TE_USB_FX2_CyAPI\FileToExportForApplication
