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
