一个使用VtoolsD类库处理硬件中断的VxD应用

// hwint.h - include file for VxD HWINT, see hwint.cpp for details

#include <vtoolscp.h>		// Primary include for VtoolsD class library
#include "realclk.h"		// Include for our Real Time Clock class
#include "bellevt.h"		// Include for our bell event class

// Device parameters

#define HWINT_Major		1
#define HWINT_Minor		0

// The Device Class
//
// The device only needs two control message handlers: DEVICE_INIT and
// SYSTEM_EXIT.
