文章举例说明了在Ｗｉｎｄｏｗｓ ＮＴ 核心模式驱动程序与用户模式应用程序之间实现通信的一种方法，介绍了如何创建及在两者之间如何共享同一Ｓｅｍａｐｈｏｒｅ 同步对象的方法，以及驱动程序如何通过改变该同步对象的状态来唤醒应用程序以最终完成在两种不同模式程序之间通信的方法。
The article illustrates one way to communicate between a Windows NT kernel-mode driver and a user-mode application, how to create and how to share the same Semaphore synchronization object between them, and how the driver can change by changing The state of the synchronization object to wake up the application to eventually complete the method of communication between two different mode programs.
