进程(process..进程(process)和线程(thread)是操作系统的基本概念,但是它们比较抽象,不容易掌握。最近,我读到一篇材料,发现有一个很好的类比,可以把它们解释地清晰易懂。1、计算机的核心是CPU,它承担了
当调用系统服务时,主调线程会从用户模式切换到内核模式,调用结束后再返回到用户模式,也就是所谓的模式切换。在线程的KTHREAD结构中,定义了UserTime和KernelTime两个字段,分别用来记录这个线程在用户模式和内核模式的运行时间(以时钟中断次数为单位)。模式切换是通过软中断或专门的快速系统调用(fast system call)指令来...
另外,TEB包括thread-local storage data。在多线程应用程序中,常会出现维护一个线程独有的数据的寻求。这个线程指定数据存储的地方叫thread-local storage。通过下面这个链接了解更多关于thread-local storage信息:、 http://msdn.microsoft.com/en-us/library/windows/desktop/ms686749(v=vs.85).aspx TEB的一些重要属...
