For a pipeline filesrc ! spider ! audiosink, do:

static gboolean
seek (guint64 ns)
  GstEvent *event;
  GstElement *audiosink = ..;

  event = gst_event_new_seek (GST_SEEK_METHOD_SET | GST_FORMAT_TIME,
  return gst_element_send_event (audiosink, event);  

And yes, the application development manual needs work... ;).
