Instructions for using the events.emitter.removeListener method in node.js_node.js

emitter.removeListener(event, listener)

var callback = function(stream) {
console.log('someone connected!');
};
server.on('connection', callback);
// ...
server.removeListener('connection', callback);

// emits a 'removeListener' event iff the listener was removed
