All I had to do prior to starting the event loop was the following:

    ev = HTEvent_new(commandCallback,
                     server_data,   /* some event specific data */
                     HT_PRIORITY_MAX,
                     timer);        /* non zero timer value */

    HTEvent_register(sock, HTEvent_READ, ev);


Where sock used to be a local Unix Socket (I wouldn't trust UDP, in
addition, you would also have to check that nobody else connects to the
socket via the network). For me this worked without problems, subsequently
written data caused the commandCallback to be triggered (again).
