一个使用匿名管道实现进程间通讯的程序

多线程相关，值得一看哦-multithreading related eye-catcher oh

先用BACC编译,再用BAINTERP运行-using the BACC compiler, and then run BAINTERP

编写并调试一个模拟的进程调度程序，采用“最高优先数优先”调度算法对五个进程进行调度。 　　“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。 　　静态优先数是在创建进程时确定的，并在整个进程运行期间不再改变。 　　动态优先数是指进程的优先数在创建进程时可以给定一个初始值，并且可以按一定原则修改优先数。例如 ：在进程获得一次CPU后就将其优先数减少1。或者，进程等待的时间超过某一时限时增加其优先数的值，等等 -Write and debug a simulation of the process scheduler, using the "highest priority number priority" scheduling process scheduling algorithm to five. The "highest priority number first" scheduling algorithm the basic idea is to CPU allocated to the highest-priority ready queue in the process. Static priority number is determined when creating the process, and in the whole process will not change during the operation. Dynamic priority number refers to the process of creating a process priority number can be given an initial value, and can modify the priority number according to certain principles. Example : In the process, get a CPU after its reduction in the number one priority. Or, the process of waiting time exceeds a certain time limit, increase

此为操作系统实验报告：虚拟存储器 内含：程序流程图 设计思路 主要源码等等。 简介：在计算机系统中，为了提高主存利用率，往往把辅助存储器（如磁盘）作为主存储器的扩充，使多道运行的作业的全部逻辑地址空间总和可以超出主存的绝对地址空间。用这种办法扩充的主存储器称为虚拟存储器。通过本实验帮助同学理解在分页式存储管理中怎样实现虚拟存储器。-experimental operating system for this report : virtual memory consisting of : flowchart design major source so on. Description : in the computer system, in order to increase the utilization rate of survival, often auxiliary memory (such as disks) as a main memory expansion, multi-channel operation run the logic address space can exceed the sum of the absolute main memory address space. Use this method to expand the main memory known as virtual memory. Through this experiment to help students understand the paging storage management how to achieve virtual memory.

用C#实现的一个进程管理器，能显示出系统中所有进程，及对其进行终止等操作，值得一看。-C# a process manager, will show all system processes, and its termination of operations overseas.

采用事件的线程同步操作-use the thread synchronization

在NT环境下隐藏进程，也就是说在用户不知情的条件下，执行自己的代码的方法有很多种，比如说使用注 册表插入DLL，使用Windows挂钩等等。其中比较有代表性的是Jeffrey Richer在《Windows核心编程》中 介绍的LoadLibrary方法和罗云彬在《Windows环境下32位汇编语言程序设计》中介绍的方法。两种方法的 共同特点是：都采用远程线程，让自己的代码作为宿主进程的线程在宿主进程的地址空间中执行，从而达 到隐藏的目的。相比较而言，Richer的方法由于可以使用c/c++等高级语言完成，理解和实现都比较容易 ，但他让宿主进程使用LoadLibrary来装入新的DLL，所以难免留下蛛丝马迹，隐藏效果并不十分完美。罗 云彬的方法在隐藏效果上绝对一流，不过，由于他使用的是汇编语言，实现起来比较难（起码我写不了汇 编程序:)）。笔者下面介绍的方法可以说是对上述两种方法的综合：采用c/c++编码，实现完全隐藏。并 且，笔者的方法极大的简化了远程线程代码的编写，使其编写难度与普通程序基本一致。-the NT environment hidden process, the user is unaware of the conditions, the implementation of their code There are various ways, for instance, the use of the registry into DLL, etc. linked to the use of Windows. The more representative Jeffrey Richer is the "core Windows programming" introduced by the LoadLibrary method and the Luo Bin, "under Windows 32 assembly language programming" introduced by the method. Two methods are common features are : remote threads are used to keep the code as host process threads in t
