There can be events needing to be flushed if the ring was full and had overflowed. Alternatively if the ring was setup with the .BR IORING_SETUP_DEFER_TASKRUN flag then this will process outstanding tasks, possibly resulting in more CQEs. .SH RETURN VALUE On success .BR io_uring_get_events (3) returns 0. On failure it returns .BR -errno . .SH SEE ALSO .BR io_uring_get_sqe (3), .BR io_uring_submit_and_get_events (3), .BR io_uring_cq_has_overflow (3)
