在Visual C++中使用内联汇编不需要额外的编译器和联接器，且可以处理Visual C++中不能处理的一些事情，而且可以使用在C/C++中的变量，所以非常方便。内联汇编主要用于如下场合:



　　1.使用汇编语言写函数；

　　2.对速度要求非常高的代码；

　　3.设备驱动程序中直接访问硬件；

　　4.\"Naked\" Call的初始化和结束代码。

-used in conjunction with the compilation does not need additional compiler and connectivity devices, which can be dealt with Visual C can not handle some things that can be used in the C / C variables, so it is convenient. In conjunction with the compilation mainly for the following occasions : 1. The use of assembly language to write function; 2. The very high speed code; 3. Device driver had direct access to hardware; 4. "Naked" Call the initialization and termination code.
