#include <qb/qbloop.h>

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 */
);

PARAMS¶
