这是我自己编写实现的一个基于设备驱动的本地进线程通信方法。该方法需要用到设备文件来联系两个没有亲缘关系的进线程。资料中包含Makefile文件，根据自己的Linux系统，可以编译出模块程序。里面附带了简单的例程用来进行测试。-This is what I have written to achieve a local-based device driver into the thread communication methods. Need to use the device file to link the two thread which have no genetic relationship. Modify the　Makefile　according to your own Linux system, you can compile to get the module program. With a simple routine which is used for testing.
