来自「pci的驱动程序编程基本框架,在此基础上编程非常方便,实现了由PCI进行DMA传」· 代码 · 共 22 行

This directory holds the code to build a PCI driver that will map
device memory info user space.  (Note: It is not a good idea to map
memory into user space because a user space program can then crash 
the machine.  For bring a PCI device up for the first time, however,
this can be a useful utility).  It assumes that the device is a frame
buffer, buf that assumption can be changed.  To build it, you will
need the Microsoft Windows NT DDK.  It has been tested under the
NT 3.51 DDK.  Use the 'build' command to create the driver.

makefile		Standard NT makefile for device drivers
maptest.c		A very small program that can map the PCI memory
			  into user space.  It will be built by default
			  with the 'build' command, but it can also be
			  created with the Microsoft Visual C++ 2.0
			  project maptest.mak
maptest.mak		A Microsoft Visual C++ 2.0 project file
skeleton.c		A skeleton device driver that will locate and map
			  a PCI device.
skeleton_dev.h		Defines the extended device structure
skeleton_nt.h		Defines the ioctls
sources			Specifies what the 'build' command should do.
