Socket.io

I'm running into an issue regarding getting all clients associated with a room.
I feel like there lacks a lot of documentation, and all Stackoverflow answers are outdated.
Back in v1 you could do this to retrieve the clients: io.sockets.clients(roomId)
So does any of you know how that is done now?

Maybe:

io.of(whatever).in(roomId).clients( function(err, clients) {
  if(err) throw err;
  console.log(clients);
});

.of(whatever) == namespace
.in(roomId) == room id (obviously)
