看看这个网页吧，里面说得满清楚的了

我这个文章我看过了，如果不用vector，怎么样才能取出ip，subnet mask等信息呢？关键是。请你指点迷津。

[kevinaniu]

如果我的程序移到内核上去的话，STL可以用吗？谢谢，请高人指点。

Module Name:

Ipconfig.cpp

Abstract:

This module illustrates how to programmatically retrieve IP configuration
information similar to the IPCONFIG.EXE utility. It demonstrates how to use
the IP Helper APIs GetNetworkParams() and GetAdaptersInfo().

To execute this application, simply build the application using the Microsoft Visual C++
nmake.exe program generation utility to make an executable ipconfig.exe. After the
build is complete, simply execute the resulting ipconfig.exe program.
