Functions

func Compactz

func Compactz(argv []byte) []byte

Compactz returns nil if argument is empty or zero

func GobDecode

func GobDecode(v []byte, e interface{}) error

GobDecode decodes a gob-encoded value v.

func GobEncode

func GobEncode(e interface{}) ([]byte, error)

GobEncode encodes e by using gob and returns.

func HandleKillSig

func HandleKillSig(handler func(), logger *log.Logger)

HandleKillSig gets killing signals (interrupt, quit and terminate) and calls a registered handler function for cleanup. Finally, this will exit program

func IsZero

func IsZero(argv []byte) bool

IsZero returns true if argument is empty or zero

func PathMkdirAll

func PathMkdirAll(paths ...string) string

PathMkdirAll make a path by joining paths and create directory if not exists
