get result from users.find() function

[profesoralex]

Hi! I have the code:

var sys = require('sys'); var nStore = require('nstore/lib/nstore').extend(require('nstore/lib/nstore/query')()); var users = nStore.new('data/users.db', function (){
users.find({user: "alex", pass:"123"}, (function(err, results) { if(err) { sys.puts('not found...'); } else { sys.puts(results.creationix.room); } })); });

What I need is something like:

var sys = require('sys'); function routeToRoom(userId,passw){ var roomId=0; var nStore = require('nstore/lib/nstore').extend(require('nstore/lib/nstore/query')()); var users = nStore.new('data/users.db', function (){
users.find({user: userId, pass:passw}, (function(err, results) { if(err) { roomId=-1; } else { roomId=results.creationix.room; } })); }); return roomId; } sys.puts(routeToRoom("alex","123"));

But I get always: 0

I guess "return roomId;" is executed before that " roomId=results.creationix.room;" . Could someone help me whit this code? Thanks in advance!
