Functions

func SdNotify

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
