registry key for getting active network interface name

Hi All,

Can any one tell me how to get the active network interface name using C and windows API?
From web I came to know that that active interface name is found at:

Code:

---

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\{GUID of Adapter}\Connection

---

Under this key, we have Name which gives name as "Local Area Connection/ wireless network connection....".

I need to get the value at that Name Field through program.
How to find this {GUID of Adapter}?
Please help me with sample code which does registry accesses to get this active interface name?

GIYF. Registry functions should be at MSDN.

Thank you dude
