NAME top

       io_uring_register_napi - register NAPI busy poll settings

SYNOPSIS top

       #include <liburing.h>

       int io_uring_register_napi(struct io_uring *ring,
                                  struct io_uring_napi *napi)

DESCRIPTION top

       The io_uring_register_napi(3) function registers the NAPI
       settings for subsequent operations. The NAPI settings are
       specified in the structure that is passed in the napi parameter.
       The structure consists of the napi timeout busy_poll_to (napi
       busy poll timeout in us) and prefer_busy_poll.

       Registering a NAPI settings sets the mode when calling the
       function napi_busy_loop and corresponds to the
       SO_PREFER_BUSY_POLL socket option.

       NAPI busy poll can reduce the network roundtrip time.

RETURN VALUE top

       On success io_uring_register_napi(3) return 0. On failure they
       return -errno.  It also updates the napi structure with the
       current values.
