QB_LOOP_POLL_ADD(3) libqb Programmer's Manual QB_LOOP_POLL_ADD(3)

qb_loop_poll_add - Add a poll job to the mainloop.

#include <qb/qbloop.h>

int32_t qb_loop_poll_add(
    qb_loop_t                *l,
    enum qb_loop_priority     p,
    int32_t                   fd,
    int32_t                   events,
    void                     *data,
    qb_loop_poll_dispatch_fn  dispatch_fn
);

l pointer to the loop instance

p the priority

fd file descriptor.

events (POLLIN|POLLOUT) etc ....

data user data passed into the dispatch function

dispatch_fn callback function


enum qb_loop_priority {
      QB_LOOP_LOW;
      QB_LOOP_MED;
      QB_LOOP_HIGH;
};

status (0 == ok, -errno == failure)

it is a re-occurring job.
