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
