io_uring_cqe_seen(3)

io_uring_cqe_seen3

Mark io_uring completion event as consumed

Usage

#include <liburing.h>

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

Overview

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
