       io_uring_sq_ready - number of unconsumed or unsubmitted entries

       #include <liburing.h>

       unsigned io_uring_sq_ready(const struct io_uring *ring);

DESCRIPTION

       The io_uring_sq_ready(3) function returns the number of
       unconsumed (if SQPOLL) or unsubmitted entries that exist in the
       SQ ring belonging to the ring param.

       Usage of this function only applies if the ring has been setup
       with IORING_SETUP_SQPOLL, where request submissions, and hence
       consumption from the SQ ring, happens through a polling thread.

       SQ ring.
