System.Taffybar.Information.Network
Description
Provides information about network traffic over selected interfaces,
obtained from parsing the /proc/net/dev file using some of the
facilities provided by the System.Taffybar.Information.StreamInfo module.

Documentation
getNetInfo :: String -> IO (Maybe [Int]) Source #
Returns a two-element list containing the current number of bytes received
and transmitted via the given network interface (e.g. "wlan0"), according
to the contents of the /proc/dev/net file.
