Types

type Header

type Header struct {
	Size         uint16
	Method       string
	PackedSize   uint64
	OriginalSize uint64
	Time         time.Time
	Attribute    uint8
	Level        uint8
	CRC          uint16
	OSID         uint8

	HeaderCRC *uint16
	Name      string
	Dir       string
	DOS       struct {
		Attr uint16
		Time uint64
	}
	UNIX struct {
		Perm  uint16
		GID   uint16
		UID   uint16
		Group string
		User  string
		Time  time.Time
	}
}

Header is header of file in LHA archive.

type Reader

type Reader struct {
	// contains filtered or unexported fields
}

Reader is LHA archive reader.

func NewReader

func NewReader(r io.Reader) *Reader

NewReader creates LHA archive reader.

func (*Reader) CRC16

func (r *Reader) CRC16() uint16

CRC16 returns current CRC16 value.

func (*Reader) Decode

func (r *Reader) Decode(w io.Writer) (decoded int, err error)

Decode decodes a file to w. It returns decoded size and error.

func (*Reader) NextHeader

func (r *Reader) NextHeader() (h *Header, err error)

NextHeader reads a next file header.
