Fields§

§smooth_sync: bool

< set to true if smooth sync required

§server_from_dhcp: bool

< set to true to request NTP server config from DHCP

§wait_for_sync: bool

< if true, we create a semaphore to signal time sync event

§start: bool

< set to true to automatically start the SNTP service

§sync_cb: Option<unsafe extern "C" fn(_: *mut timeval)>

< optionally sets callback function on time sync event

§renew_servers_after_new_IP: bool

< this is used to refresh server list if NTP provided by DHCP (which cleans other pre-configured servers)

§ip_event_to_renew: u32

< set the IP event id on which we refresh server list (if renew_servers_after_new_IP=true)

§index_of_first_server: usize

< refresh server list after this server (if renew_servers_after_new_IP=true)

§num_of_servers: usize

< number of preconfigured NTP servers

§servers: [*const i8; 1]

< list of servers
