摘要
描述了文件系统驱动与文件系统过滤驱动的关系,通过对文件系统响应用户模式应用程序操作请求原理的分析,得出文件系统过滤驱动入口函数的编写方式,以及关键分发例程的实现方法,并给出了用户模式应用程序与内核模式文件系统过滤驱动程序进行通信的方式.
The relation between file system driver and file system filter driver is described firstly. On the analysis of the procedure that the file system responds to the applications＇ requests, the way how to program the file system filter driver＇ s main function is put forward, in addition, the methods to programming several important dispatch functions are brought forward. Furthermore, the means how the applications in user mode communicates with file system filter driver in kernd mode is described in detail.
