io_uring_cqe_seen - Man Page
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
