线程的同步
虽然多线程能给我们带来好处，但是也有不少问题需要解决。例如，对于像磁盘驱动器这样独占性系统资源，由于线程可以执行进程的任何代码段，且线程的运行是由系统调度自动完成的，具有一定的不确定性，因此就有可能出现两个线程同时对磁盘驱动器进行操作，从而出现操作错误；又例如，对于银行系统的计算机来说，可能使用一个线程来更新其用户数据库，而用另外一个线程来读取数据库以响应储户的需要，极有可能读数据库的线程读取的是未完全更新的数据库，因为可能在读的时候只有一部分数据被更新过。-thread synchronization Although multithreading can bring us benefits, but there a lso many problems to be solved. For example, as disk drives such exclusivity system resources and can thread the process of implementation of any code, and the thread running by the scheduling system automatically and to a certain extent the uncertainty, So, then there could be two threads while the disk drives operate, which have operational errors; For example, For the computer banking system, may use a thread to update users of its database, and use another thread to read a database to respond to the needs of depositors, Reading is very likely to read threads database is not fully update the database, Reading may be because the time was only part of the updated dat

与pssetcreateprocessnotifyroutine，pssetcreatethreadnotifyroutine线程问题。
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. Sinister In "" A text has been achieved in very good. Some time ago the Internet was seen in the surveillance study of the threads from article more interesting.
