How to use the node.io.start function in node

var start_job = function(job) {
            nodeio.start(job, function (err, output) {

                }
            }, true);
        };
        start_job(job1);

verbose(e);
        }

        this.emit(obj);
      });
    }
  };

  var job = new nodeio.Job({
