) const COFFSymbolSize = 18
COFFSymbol represents single COFF symbol table record.
type COFFSymbol struct {
Name [8]uint8
Value uint32
SectionNumber int16
Type uint16
StorageClass uint8
NumberOfAuxSymbols uint8
} func (sym *COFFSymbol) FullName(st StringTable) (string, error)
FullName finds real name of symbol sym. Normally name is stored in sym.Name, but if it is longer then 8 characters, it is stored in COFF string table st instead.
type DataDirectory struct {
VirtualAddress uint32
Size uint32
} A File represents an open PE file.
type File struct {
FileHeader
OptionalHeader interface{} // of type *OptionalHeader32 or *OptionalHeader64
Sections []*Section
Symbols []*Symbol // COFF symbols with auxiliary symbol records removed
COFFSymbols []COFFSymbol // all COFF symbols (including auxiliary symbol records)
StringTable StringTable
// contains filtered or unexported fields
} func NewFile(r io.ReaderAt) (*File, error)
NewFile creates a new File for accessing a PE binary in an underlying reader.
func Open(name string) (*File, error)
Open opens the named file using os.Open and prepares it for use as a PE binary.
func (f *File) Close() error
Close closes the File. If the File was created using NewFile directly instead of Open, Close has no effect.
func (f *File) DWARF() (*dwarf.Data, error)
func (f *File) ImportedLibraries() ([]string, error)
ImportedLibraries returns the names of all libraries referred to by the binary f that are expected to be linked with the binary at dynamic link time.
func (f *File) ImportedSymbols() ([]string, error)
ImportedSymbols returns the names of all symbols referred to by the binary f that are expected to be satisfied by other libraries at dynamic load time. It does not return weak symbols.
func (f *File) Section(name string) *Section
Section returns the first section with the given name, or nil if no such section exists.

} Reloc represents a PE COFF relocation. Each section contains its own relocation list.
type Reloc struct {
VirtualAddress uint32
SymbolTableIndex uint32
Type uint16
} Section provides access to PE COFF section.
type Section struct {
SectionHeader
Relocs []Reloc
// Embed ReaderAt for ReadAt method.
// Do not embed SectionReader directly
// to avoid having Read and Seek.
// If a client wants Read and Seek it must use
// Open() to avoid fighting over the seek offset
// with other clients.
io.ReaderAt
// contains filtered or unexported fields
} func (s *Section) Data() ([]byte, error)
Data reads and returns the contents of the PE section s.
func (s *Section) Open() io.ReadSeeker
Open returns a new ReadSeeker reading the PE section s.
SectionHeader is similar to SectionHeader32 with Name field replaced by Go string.
type SectionHeader struct {
Name string
VirtualSize uint32
VirtualAddress uint32
Size uint32
Offset uint32
PointerToRelocations uint32
PointerToLineNumbers uint32

} StringTable is a COFF string table.
type StringTable []byte
func (st StringTable) String(start uint32) (string, error)
String extracts string from COFF string table st at offset start.
Symbol is similar to COFFSymbol with Name field replaced by Go string. Symbol also does not have NumberOfAuxSymbols.
type Symbol struct {
