       int32_t qb_loop_signal_add(
           qb_loop_t                  *l, /* pointer to the loop instance */
           enum qb_loop_priority       p, /* the priority */
           int32_t                     sig,  /* (SIGHUP or SIGINT) etc .... */
           void                       *data,   /* user data passed into the dispatch function */
           qb_loop_signal_dispatch_fn  dispatch_fn,          /* callback function */
           qb_loop_signal_handle      *handle     /* (out) a reference to the signal job */
       );
