NAME

       io_uring_cq_advance - mark one or more io_uring completion events as consumed

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 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).

       The function io_uring_cqe_seen(3) calls the function io_uring_cq_advance(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 invocation.

RETURN VALUE

       None
