linux操作系统学习实践 －－－main.c

main.c
 I don't mean to write the whole OS kernel.I just want to put what I have
 already learned into practice.But what will it be end up looking like.
 I don't know.ALA I have some free time,I will write something.Just like
 linus once said,"Just for fun".I don't care what this small ugly codes
 will be capable of,or does it worth something.I just write it for fun,
 and for practice.
