func Mkdev added in v1.4.0

func Mkdev(major int64, minor int64) uint32

Linux device nodes are a bit weird due to backwards compat with 16 bit device nodes. They are, from low to high: the lower 8 bits of the minor, then 12 bits of the major, then the top 12 bits of the minor

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
