Types

type ADV

type ADV []byte

ADV represents the Syslinux Auxiliary Data Vector.

func NewADV

func NewADV(r io.ReadSeeker) (adv ADV, err error)

NewADV returns the Auxiliary Data Vector.

func (ADV) Bytes

func (a ADV) Bytes() ([]byte, error)

Bytes returns serialized contents of ADV.

func (ADV) DeleteTag

func (a ADV) DeleteTag(t uint8) (ok bool)

DeleteTag deletes a tag in the ADV.

func (ADV) ReadTag

func (a ADV) ReadTag(t uint8) (val string, ok bool)

ReadTag reads a tag in the ADV.

func (ADV) ReadTagBytes

func (a ADV) ReadTagBytes(t uint8) (val []byte, ok bool)

ReadTagBytes reads a tag in the ADV.

func (ADV) SetTag

func (a ADV) SetTag(t uint8, val string) bool

SetTag sets a tag in the ADV.

func (ADV) SetTagBytes

func (a ADV) SetTagBytes(t uint8, val []byte) (ok bool)

SetTagBytes sets a tag in the ADV.
