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.
