钩子是WINDOWS中消息处理机制的一个要点，通过安装各种钩子，应用程序能够设置相应的子例程来监视系统里的消息传递以及在这些消息到达目标窗口程序之前处理它们。钩子的种类很多，每种钩子可以截获并处理相应的消息，如键盘钩子可以截获键盘消息，鼠标钩子可以截获鼠标消息，外壳钩子可以截获启动和关闭应用程序的消息，日志钩子可以监视和记录输入事件。钩子分为线程专用钩子和全局钩子，线程专用钩子只监视指定的线程，要监视系统中的所有线程，必须用到全局钩子。对于全局钩子，钩子函数必须包含在独立的动态链接库(DLL)中，这样才能被各种相关联的应用程序调用。

hook
A point in the Windows message-handling mechanism where an application can install a subroutine to monitor messages.
hook chain
A list of pointers to the hook procedures associated with a hook. When a message occurs that is monitored by the hook, Windows calls the first hook procedure in the chain.
hook procedure
