io_uring_get_events(3) liburing Manual io_uring_get_events(3)
io_uring_get_events - Flush outstanding requests to CQE ring
#include <liburing.h>
int io_uring_get_events(struct io_uring *ring);
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.
On success io_uring_get_events(3) returns 0. On failure it
returns -errno.
