avahi.go

package main

import (
        "github.com/guelfey/go.dbus"
        "log"
        "bufio"
        "os"

func main() {
        var dconn *dbus.Conn
        var obj *dbus.Object
        var path dbus.ObjectPath
        var err error

        dconn, err = dbus.SystemBus()
        if err != nil {
                log.Fatal("Fatal error ", err.Error())
        }

        obj = dconn.Object("org.freedesktop.Avahi", "/")
        obj.Call("org.freedesktop.Avahi.Server.EntryGroupNew", 0).Store(&path)

        obj = dconn.Object("org.freedesktop.Avahi", path)

        var AAY [][]byte
        for _, s := range []string{"[email protected]", "[email protected]", "status=avail"} {
                AAY = append(AAY, []byte(s))
        }

        // http://www.dns-sd.org/ServiceTypes.html
        obj.Call("org.freedesktop.Avahi.EntryGroup.AddService", 0,
