sample code to programmatically detect wlan0

Hi,

I need to start a service (using systemd) only after wlan0 is up.
How can I detect it programmatically?

Sample code in g++ would be great. I'm using Angstrom v2012.05
Cheers

Not completely sure, but I think your requirement falls into the domain of udev. Perhaps research the problem form that angle.

I think you could parse the output of both 'ifconfig' and 'iwconfig'. ifconfig will show you if the interface is up and iwconfig will show you that it is authenticated at the access point.
