# GCC-Inline-Assembly-HOWTO
# GCC内联汇编HOWTO
v0.1, 01 March 2003.
* * *
_This HOWTO explains the use and usage of the inline assembly feature provided by GCC. There are only two prerequisites for reading this article, and that’s obviously a basic knowledge of x86 assembly language and C._
_本HOWTO文档将讲解GCC提供的内联汇编特性的用途和用法。对于阅读这篇文章，这里只有两个前提要求，很明显，就是x86汇编语言和C语言的基本认识。_

## 2. Overview of the whole thing.
## 2. 概览
We are here to learn about GCC inline assembly. What this inline stands for?
在这里，我们将学习GCC内联汇编。这内联表示的是什么呢？
我们可以要求编译器将一个函数的代码插入到调用者代码中函数被实际调用的地方。这样的函数就是内联函数。这听起来和宏差不多？这两者确实有相似之处。
We can instruct the compiler to insert the code of a function into the code of its callers, to the point where actually the call is to be made. Such functions are inline functions. Sounds similar to a Macro? Indeed there are similarities.
What is the benefit of inline functions?
