type File 

type File struct {
	FileHeader
	Sections []*Section
	Progs    []*Prog
	// contains filtered or unexported fields
}

A File represents an open ELF file.

func NewFile 

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

NewFile creates a new File for accessing an ELF binary in an underlying reader. The ELF binary is expected to start at position 0 in the ReaderAt.

func Open 

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

Open opens the named file using os.Open and prepares it for use as an ELF 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) DynString 

func (f *File) DynString(tag DynTag) ([]string, error)

DynString returns the strings listed for the given tag in the file's dynamic section.

The tag must be one that takes string values: DT_NEEDED, DT_SONAME, DT_RPATH, or DT_RUNPATH.

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() ([]ImportedSymbol, 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 a section with the given name, or nil if no such section exists.

func (*File) SectionByType 

func (f *File) SectionByType(typ SectionType) *Section

SectionByType returns the first section in f with the given type, or nil if there is no such section.

func (*File) Symbols 

func (f *File) Symbols() ([]Symbol, error)

Symbols returns the symbol table for f.

For compatibility with Go 1.0, Symbols omits the null symbol at index 0. After retrieving the symbols as symtab, an externally supplied index x corresponds to symtab[x-1], not symtab[x].
