NAME

       io_uring_get_events - Flush outstanding requests to CQE ring

SYNOPSIS

       #include <liburing.h>

       int io_uring_get_events(struct io_uring *ring);

DESCRIPTION

       The io_uring_get_events(3) function runs outstanding work and
       flushes completion events to the CQE ring.

       There can be events needing to be flushed if the ring was full
       and had overflowed.  Alternatively if the ring was setup with the
       IORING_SETUP_DEFER_TASKRUN flag then this will process
       outstanding tasks, possibly resulting in more CQEs.

RETURN VALUE

       On success io_uring_get_events(3) returns 0. On failure it
       returns -errno.
