这篇文章是有关在OS Windows下挂钩API函数的方法。所有例子都在基于NT技术的Windows版本NT 4.0及以上有效(Windows NT 4.0, Windows 2000, Windows XP)。可能在其它Windows系统也会有效。

你应该比较熟悉Windows下的进程、汇编器、PE文件结构和一些API函数，才能明白这篇文章里的内容。

这里使用\"Hooking API\"这个术语表示对API的完全修改。当调用被挂钩的API时，我们的代码能立刻被执行。我将写下完全的挂钩过程。

-This article is concerned with the OS Windows API function linked to the method. All the examples are based on the NT version of Windows NT 4.0 and above effective (Windows NT 4.0, Windows 2000, Windows XP). In other Windows system will effectively. You may be familiar with the process under Windows, assembler, PE file structure and some API function, in order to understand this article's content. Here the use of "56.6 API," said the term of the complete API changes. When the call was linked to the API, the code can be executed immediately. I will write entirely linked to the process.
