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.
