NAME
       io_uring_submit_and_get_events - submit requests to the submission
       queue and flush completions

SYNOPSIS

DESCRIPTION

       The benefit of this function is that it does both with only one system
       call.

       submitted submission queue entries. On failure it returns -errno.
