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 added in v1.1.0 

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) DynamicSymbols added in v1.4.0 

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

DynamicSymbols returns the dynamic symbol table for f. The symbols will be listed in the order they appear in f.

For compatibility with Symbols, DynamicSymbols 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].

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. The symbols will be listed in the order they appear in 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].
