摘要
介绍了VxD的工作原理及Windows98的中断机制,讨论了数据采集虚拟设备驱动程序VxD的编程方法,给出了由VC++6.0编写的Win32应用程序实例,很好地实现与负责处理数据采集卡硬件中断的VxD进行通信.
This paper discusses the principle of VxD′s working and the mechanism of Windows98′s interruption. The VxD programming method for data acquisition is presented and a Win32 application example which is compiled through VC++6.0 is given, the application realizes communication with VxD used to handle hardware interruption for data acquisition card.
