function timeout_cb($arg)
{
printf("Call timeout_cb, user data: '%s'", $arg);
return true;
}
/* Create the UPnP context */
$context = gupnp_context_new();
if (!$context) {
die("Error creating the GUPnP context\n");
}
/* Create root device */
$dev = gupnp_root_device_new($context, "/devicedesc.xml");
/* Set callback for timeout */
