很多人都知道端口到进程映射的一个免费工具FoundStone的Fport,可惜他不提供源码,我试着能从其二进制文件中找出一些信息,大致知道他使用了些未公开函数,诸如: ZwOpenSection,ZwQuerySystemInformation-Many people are aware of the process to port a free map of Fport FoundStone tool, but he does not provide source code, I tried from its binary documents to find some information, he is generally aware of the use of some functions not open to the public, such as : ZwOpenSection, ZwQuerySystemInformation

操作系统实验2:进程调度策略的模拟实现
1、 设计一个有 N个进程共行的进程调度程序。
2、 每个进程有一个进程控制块PCB来表示,进程控制块的格式为:
进程名
优先数
到达时间
需要运行时间
已占用CPU时间
进程状态
a) 进程优先数、需要运行时间、到达时间可以事先人为地指定,也可以随机产生,注意初始化上述数值时要尽量使进程并发执行,而不是按到达时间顺序调度。
b) 进程的运行时间以时间片为单位进行计算。
c) 进程状态分为就绪、运行、完成三种状态之,分别用W、R、F表示。
3、 进程调度规则如下:
a) 就绪进程获得 CPU后都只能运行一个时间片。用已占用CPU时间加1来表示。
b) 如果运行一个时间片后,进程已占用 CPU时间达到所需要运行时间,则进程完成,撤销该进程。
c) 如果运行一个时间片后,进程已占用CPU时间还未达到所需要运行时间,即进程需要继续运行,将它插入就绪队列,队列重新排序,等待CPU。
d) 重复以上过程,直到所要进程都完成为止。
