SYNOPSIS         top

       #include <liburing.h>

       int io_uring_submit_and_wait(struct io_uring *ring,
                                    unsigned wait_nr);

DESCRIPTION         top

       The io_uring_submit_and_wait(3) function submits the next
       requests from the submission queue belonging to the ring and
       waits for wait_nr completion events.

       After the caller retrieves a submission queue entry (SQE) with
       io_uring_get_sqe(3) and prepares the SQE, it can be submitted
       with io_uring_submit_and_wait(3).

RETURN VALUE         top

       On success io_uring_submit_and_wait(3) returns the number of
       submitted submission queue entries. On failure it returns -errno.
