用PsSetCreateProcessNotifyRoutine,PsSetCreateThreadNotifyRoutine来进行进程线程监控我想大家已经都非常熟练了.sinister在一文中已经实现得很好了.前一段时间看到网上有人在研究监视远线程的文章,比较有意思.就写代码玩一玩.这之中就出现了一些问题.比方说直接用sinister的代码的话,是不能动态卸载的,因为他在安装了进线程监视函数后没有进行清除动作,造成在动态卸载时蓝屏,BUGCHECK为0x000000ce,错误码为:DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS.很显然,在驱动退出后,一些进线程操作仍然在访问原来的地址,造成出错.在XP后,微软给出了一个函数PsRemoveCreateThreadNotifyRoutine用来清除线程监视函数(清除进程监视的就是PsSetCreateProcessNotifyRoutine).我一直奇怪ICESWORD在2000中是怎么做到进线程监视的.后来才发现,在运行icesword后释放出一个detport.sys文件,然后一直在系统中存在着没有卸载掉.只是把它隐藏了而已^_^.这不是个好消息,难道我为了测试一个驱动,测试一次就得重启一次吗?呵呵,肯定不是啊,所以想办法搞定它.-with PsSetCreateProcessNotifyRoutine, PsSetCreateThreadNotifyRoutine thread to process control, I think we had a very skilled.

此为操作系统实验:进程同步机制的模拟实现. 报告中有 程序流程图 解题思路 部分主要源码等!! 简介:进程是程序在一个数据集合上运行的过程，进程是并发执行的，也即系统中的多个进程轮流地占用处理器运行。 我们把如干个进程都能进行访问和修改地那些变量成为公共变量。由于进程是并发执行的，所以，如果对进程访问公共变量不加限制，那么就会产生“与时间有关”的错误，即进程执行后，所得到的结果与访问公共变量的时间有关。为了防止这类错误，系统必须要用同步机构来控制进程对公共变量的访问。一般说，同步机构是由若干条原语――同步原语――所组成。本实验要求学生模拟PV操作同步机构的实现，模拟进程的并发执行，了解进程并发执行时同步机构的作用。-operating system for this experiment : the process synchronization mechanism Simulation.

Description : The process is procedural in a data set on the process of operation, the process is complicated by the implementation of the system that is the number of rotation process to deal with occupation Operation. We can process of stem out for a visit and to amend those variables as public variables. As the process is complicated by the implementation, so if the right to visit public process variables without restrictions, it will have a "Time" is wrong, the implementation process, the results obtained with the public
