谈到在Windows创建线程的例子，在网上的很多的参考都是基于MFC的。其实，就操作系统实验这个前提而言，大可不必去碰那个大型的MFC的框架。[1]中提到了在Windows命令控制台下创建进程及线程的方法，本文对[1]中的方法加以了实现，并做些简单的进程及线程的测试程序。
-On Windows create a thread in the examples of the many online reference are based on the MFC. In fact, experiments on this premise in terms of the operating system, no need to touch the large MFC framework. [1] mentioned in the Windows command console to create processes and threads under way, this paper [1] in the methods to achieve, and do a simple process and thread test procedures.

用C语言实现进程调度－操作系统课程设计设计思想：
“最高优先数优先”调度算法的基本思想是把cpu分配给就绪队列中优先数最高的进程。采用动态优先数，即优先数在创建进程时给定一个初始值，当进程获得一次cpu后其优先数就减少1。-C language scheduling process-design courses on operating system design : "Priority number of the highest priority" scheduling algorithm the basic idea is cpu allocated to the parade were in place the highest priority in the process. Dynamic priority, which is priority number in the creation process to set an initial value, When the process is a cpu after its priority on reducing the number of one.
