io_uring_cqe_seen(3)            liburing Manual           io_uring_cqe_seen(3)

NAME
       io_uring_cqe_seen - mark io_uring completion event as consumed

SYNOPSIS
       #include <liburing.h>

       void io_uring_cqe_seen(struct io_uring *ring,
                              struct io_uring_cqe *cqe);

DESCRIPTION
       The io_uring_cqe_seen(3) function marks the IO completion cqe 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).

       Completions must be marked as completed so their slot can get reused.

RETURN VALUE
       None
