IP Helper API Programming [VC++]

This page illustrates how to use the IP Helper API by showing simple sample codes. IP Helper API is an API for writing networking related codes on Windows platform. Using IP Helper API, you can get information about network interfaces, get network statistics, setup IP address, etc.

Please be ware that the data transmission itself is out of scope of IP Helper API. It is done by winsock.

Preparing IPHLPAPI(IP Helper API)

To use IP Helper API, you would have to install the Platform SDK. You can download Platform SDK from microsoft site.

After you downloaded Platform SDK, you need two more steps to compile IP Helper API codes. First, you would have to include iphlpapi.h somewhere in your code. Next, you would have to link two libraries, WS2_32.lib (winsock2) and iphlpapi.lib.

After you finished preparing, you can start writing your code.
