应用层与驱动层共享内存应用实例

在前一个例子SharedSection中，我们共享内存区通讯。这个驱动紧紧关联到用户模式进程的地址空间，也就是驱动所用的虚拟地址在进程空间地址中。这个例子中我们用的这个方法，没有这个缺点，对于驱动来说这个方法更适合。

首先，驱动的功能。

; SharingMemory - How to share memory between kernel-mode driver and its user-mode client

; This method is applicable only for highest-level or monolithic driver
; because of while processing IRP such driver's type is in the context
; of the requested user process which address space driver maps the memory buffer into.
