net-adapter

cross platform library for getting presentable Network Adapter information. Written in a "c style" C++.

• Network adapter names (e.g. "Wireless Network Connection", "eth0", "en0", or "em0")
• IP address (e.g. 192.168.0.184)
• Subnet Mask (e.g. 255.255.255.0)
• UDP Broadcast address (e.g. 192.168.0.255)
• MAC address (e.g. b0:90:92:01:e2:aa)

The goal of the library is to provide presentable data, so data is stored as c strings. For use, data is also available as arrays of unsigned chars and unsigned shorts (where applicable).

NOTE: net-adapter gets your PC's IP address on the local network, NOT your IP on the internet. If you want to know that, you'll have to ask an outside server on the internet. Sorry.

Usage (Primary Adapter):

#include <NetAdapter/NetAdapter.h>                                              // Or wherever you put it //

// ... //

pNetAdapterInfo* Adapters = new_pNetAdapterInfo();                              // Many Adapters (hence the "p") //

const NetAdapterInfo* Current = get_primary_pNetAdapterInfo( Adapters );        // One Adapter (no "p") //
printf( "%s: %s (%s)\n", Current->Name, Current->IP, Current->MAC );

delete_pNetAdapterInfo( Adapters );                                             // Cleanup //

Usage (All Adapters):

pNetAdapterInfo* Adapters = new_pNetAdapterInfo();

size_t AdapterCount = count_pNetAdapterInfo(Adapters);                          // Count the Adapters //
for ( size_t Index = 0; Index < AdapterCount; Index++ ) {
        const NetAdapterInfo* Current = get_pNetAdapterInfo( Adapters, Index ); // get_, not get_primary_ //
        printf( "%i - %s: %s (%s)\n", Index, Current->Name, Current->IP, Current->MAC );
}

delete_pNetAdapterInfo( Adapters );

Usage (Printing an IP address using the raw data):

const NetAdapterInfo* Ct = get_primary_pNetAdapterInfo( Adapters );
printf( "%s: %i.%i.%i.%i\n", Ct->Name, Ct->Data.IP[0], Ct->Data.IP[1], Ct->Data.IP[2], Ct->Data.IP[3] );

History

Way back in 2012, I wanted a simple way to get the IP and MAC address of the current computer. Funny thing, this is actually beyond the scope of networking libraries like ENet.

Since Google Code is shutting down, I moved it. Here is the original blog post:

# Net Adapter – AKA the “Get IP/MAC address” library
So hey. I wrote and open sourced a small cross platform library for getting 
the IP and MAC address of the current device. You can find it on Google Code.

http://code.google.com/p/net-adapter/

So far I’ve tested it on Windows, Linux (Ubuntu), and Mac OSX Mountain Lion.
It *should* also work on iOS, BSD and Android. If you happen to test it on 
one of those other platforms, I would love to know what the Sample program 
outputs. Thanks!
