#include <liburing.h>

void io_uring_cq_advance(struct io_uring *ring,
                          unsigned nr);

The io_uring_cq_advance(3) function marks nr IO completions belonging to the ring param as consumed.

After the caller has submitted a request with io_uring_submit(3), the application can retrieve the completion with io_uring_wait_cqe(3), io_uring_peek_cqe(3), or any of the other CQE retrieval helpers, and mark it as consumed with io_uring_cqe_seen(3).

The function io_uring_cqe_seen(3) calls the function io_uring_cq_advance(3).

Completions must be marked as seen, so their slot can get reused. Failure to do so will result in the same completion being returned on the next invocation.
