func SdNotify(unsetEnvironment bool, state string) (bool, error)
SdNotify sends a message to the init daemon. It is common to ignore the error. If `unsetEnvironment` is true, the environment variable `NOTIFY_SOCKET` will be unconditionally unset.
It returns one of the following: (false, nil) - notification not supported (i.e. NOTIFY_SOCKET is unset) (false, err) - notification supported, but failure happened (e.g. error connecting to NOTIFY_SOCKET or while sending data) (true, nil) - notification supported, data has been sent
func SdWatchdogEnabled(unsetEnvironment bool) (time.Duration, error)
SdWatchdogEnabled returns watchdog information for a service. Processes should call daemon.SdNotify(false, daemon.SdNotifyWatchdog) every time / 2. If `unsetEnvironment` is true, the environment variables `WATCHDOG_USEC` and `WATCHDOG_PID` will be unconditionally unset.
It returns one of the following: (0, nil) - watchdog isn't enabled or we aren't the watched PID. (0, err) - an error happened (e.g. error converting time). (time, nil) - watchdog is enabled and we can send ping. time is delay before inactive service will be killed.
