编译方法：1、将此代码剪贴保存为getmacadd.c
          2、然后在命令行状态(dos提示符下)执行：cl getmacadd.c /link netapi32.lib。这里为了保证编译顺利执行，必须保证编译程序能找到cl.exe 和netapi32.lib。否则先执行vcvars32.bat（Visual C++ 6.0环境）或者vsvars32.bat(Visual C++ 7.0环境)。编译正常完成后，输出如下：

C:\>cl getmacadd.c /link netapi32.lib
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8168 for 80×86

/out:getmacadd.exe
netapi32.lib
getmacadd.obj

执行getmacadd.exe即可。
