Interface without IP connection status

I'm on Win7 and Qt and I need to track local network interfaces. The problem is - some of them don't have IP layer but I want to know if they are connected or not.
I've tried




QNetworkInterface::allInterfaces() from Qt




and




GetInterfaceInfo() from iphlpapi.h




But both work only for interfaces with IP assigned. Duh.
I've also tried




pcap library




But pcap_if_t has no fields to track connection status, only MAC and others.
I feel stuck between two layers and don't know how to handle this.
I suppose there is a way with WMI query but it seems to be an overkill.

  • What do you mean by "connected"? Do you mean physically present on your local machine? That sounds like something for device manager functions.

  • Look at the Win32 GetAdaptersInfo() or GetAdaptersAddresses() function. They will give you detailed information and statuses of every installed network adapter.

I found out that internal interface status can be checked with the Win32 GetIfTable() function.
This example helped me a lot.
