io_uring_cqe_seen 3 "November 15, 2021" "liburing-2.1" "liburing Manual"
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
