type COFFSymbol

COFFSymbol represents single COFF symbol table record.

type COFFSymbol struct {
    Name               [8]uint8
    Value              uint32
    SectionNumber      int16
    Type               uint16
    StorageClass       uint8
    NumberOfAuxSymbols uint8
}

func (*COFFSymbol) FullName

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

type DataDirectory struct {
    VirtualAddress uint32
    Size           uint32
}

type File

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

func NewFile(r io.ReaderAt) (*File, error)

NewFile creates a new File for accessing a PE binary in an underlying reader.

func Open

func Open(name string) (*File, error)

Open opens the named file using os.Open and prepares it for use as a PE binary.

func (*File) Close

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 (*File) DWARF

func (f *File) DWARF() (*dwarf.Data, error)

func (*File) ImportedLibraries

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 (*File) ImportedSymbols

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 (*File) Section

func (f *File) Section(name string) *Section

Section returns the first section with the given name, or nil if no such section exists.

    // with other clients.

    // contains filtered or unexported fields
