func MkdirAll added in v1.7.0

func MkdirAll(path string, perm os.FileMode) error

func Mknod

func Mknod(path string, mode uint32, dev int) error

Mknod creates a filesystem node (file, device special file or named pipe) named path with attributes specified by mode and dev

func Umask

func Umask(newmask int) (oldmask int, err error)

func UtimesNano

func UtimesNano(path string, ts []syscall.Timespec) error
