Functions

func FindAddressOfSymbol

func FindAddressOfSymbol(ef *elf.File, symbol string) (uint64, error)

TODO: Optimize! FindAddressOfSymbol finds the address of the given symbol in the given elf file by searching both the symbol table and the dynamic symbol table. Returns 0 if the symbol is not found.

func FindSymbol

func FindSymbol(ef *elf.File, symbol string) (*elf.Symbol, error)

FindSymbol finds symbol by name in the given elf file.

func HasSymbols

func HasSymbols(ef *elf.File, matches [][]byte) (bool, error)

func IsSymbolNameInDynamicSymbols

func IsSymbolNameInDynamicSymbols(f *elf.File, matches [][]byte) (bool, error)

ForEachElfSymbolNameInSymbols iterates over the symbols in the dynamic symbol table of the given elf file. It calls the given function for each symbol name. The value is only valid for the iteration, it must not be saved unless copied.

func IsSymbolNameInSymbols

func IsSymbolNameInSymbols(f *elf.File, matches [][]byte) (bool, error)

ForEachElfSymbolNameInSymbols iterates over the symbols in the symbol table of the given elf file. It calls the given function for each symbol name. The value is only valid for the iteration, it must not be saved unless copied.

func IsV8

func IsV8(f *elf.File) (bool, error)

HACK: This is a somewhat a brittle check.

func ReadStringAtAddress

func ReadStringAtAddress(rs io.ReadSeeker, address, size uint64) (string, error)

ReadStringAtAddress reads a null-terminated string from the given address in the given elf file.
