After the caller has submitted a request with .BR io_uring_submit (3), the application can retrieve the completion with .BR io_uring_wait_cqe (3), .BR io_uring_peek_cqe (3), or any of the other CQE retrieval helpers, and mark it as consumed with .BR io_uring_cqe_seen (3). Completions must be marked as completed so their slot can get reused. .SH RETURN VALUE None .SH SEE ALSO .BR io_uring_submit (3), .BR io_uring_peek_cqe (3), .BR io_uring_wait_cqe (3), .BR io_uring_wait_cqes (3), .BR io_uring_wait_cqe_timeout (3)
