21 knet_link_get_status
22 knet_h - pointer to knet_handle_t
24 host_id - see knet_host_add(3)
26 link_id - see knet_link_set_config(3)
28 status - pointer to knet_link_status struct
30 struct_size - max size of knet_link_status - allows library to add
32 fields without ABI change. Returned structure will be truncated to this
33 length and .size member indicates the full size.
