What are you trying to determine from this parsing? Do you need to 
actually know the netdev name or can you get by with the address of the 
device? If you are using dat_registry_list_providers(), just walk the 
list, use the device name for the dat_ia_open and if it returns 
DAT_SUCCESS the device is active and configured. You can then call 
dat_ia_query to get the IP address.
