I think it is close to impossible to do in portable way. Most 
reliable approach is to get list of all configured network 
interfaces via posix functions (or via `system` call as least 
resort), filter out "lo" and broadcast message for every such 
interface. I think you can also filter only wireless interfaces 
that way relatively easily too.
