Types

type Auxiliary

type Auxiliary [18]byte

type Coff

type Coff struct {
	pe.FileHeader
	pe.SectionHeader32

	*Dir
	DataEntries []DataEntry
	Data        []Sizer

	Relocations []RelocationEntry
	Symbols     []Symbol
	StringsHeader
	Strings []Sizer
}

func NewRDATA

func NewRDATA() *Coff

func NewRSRC

func NewRSRC() *Coff

func (*Coff) AddData

func (coff *Coff) AddData(symbol string, data Sizer)

NOTE: only usable for Coff created using NewRDATA NOTE: symbol names must be probably >8 characters long NOTE: symbol names should not contain embedded zeroes

func (*Coff) AddResource

func (coff *Coff) AddResource(kind uint32, id uint16, data Sizer)

NOTE: function assumes that 'id' is increasing on each entry NOTE: only usable for Coff created using NewRSRC

func (*Coff) Arch

func (coff *Coff) Arch(arch string) error

NOTE: must be called immediately after NewRSRC, before any other functions.

func (*Coff) Freeze

func (coff *Coff) Freeze()

Freeze fills in some important offsets in resulting file.
