摘　　要：Windows操作系统实现了对内核的保护机制,用户级线程没有权限直接访问内核级缓冲区,不能直接与内核级线程共享缓冲区.研究了实现Windows内核线程与用户线程之间共享缓冲区的方法,包括DeviceIoControl方式和存储器映射方式,给出了部分源代码,同时分析了应用时应注意的问题.Windows realizes the protecting function to kernel; user thread has no direct access to kernel buffer or no sharing buffer with kernel thread. The paper researches the ways of realizing the sharing buffer between Windows kernel thread and user thread, including DeviceIoControl way and memory mapping way, listing some part of source code. Meanwhile it anlayses some practical and noticeable problems.

关 键 词：内核线程 用户线程 驱动程序 共享缓冲区 映射
