io_uring_cq_advance(3)		 liburing Manual	  io_uring_cq_advance(3)

NAME
     io_uring_cq_advance  -  mark one or more io_uring completion events as con-
     sumed

SYNOPSIS
     #include <liburing.h>

     void io_uring_cq_advance(struct io_uring *ring,
			       unsigned nr);

DESCRIPTION
     The io_uring_cq_advance(3) function marks nr IO  completions  belonging  to
     the ring param as consumed.

     After  the	 caller has submitted a request with io_uring_submit(3), the ap-
     plication can retrieve the	 completion  with  io_uring_wait_cqe(3),  io_ur-
     ing_peek_cqe(3),  or any of the other CQE retrieval helpers, and mark it as
     consumed with io_uring_cqe_seen(3).

     The  function  io_uring_cqe_seen(3)  calls	 the  function	 io_uring_cq_ad-
     vance(3).

     Completions  must	be marked as seen, so their slot can get reused. Failure
     to do so will result in the same completion being returned on the next  in-
     vocation.


RETURN VALUE
     None
