Argument data is an
    Elf_Data descriptor associated with a section of type
    SHT_SYMTAB, SHT_DYNSYM or
    SHT_GNU_versym. Argument ndx
    is the index of the symbol being retrieved or updated. The class-independent
    GElf_Sym structure is described in
    gelf(3).
Function gelf_getsym() retrieves
    class-dependent symbol information at index ndx in
    data buffer data and copies it to the destination
    pointed to by argument sym after translation to
    class-independent form.
Function gelf_update_sym() converts the
    class-independent symbol information pointed to by argument
    sym to class-dependent form, and writes it to the
    symbol entry at index ndx in the data buffer described
    by argument data. Function
    gelf_update_sym() signals an error if any of the
    values in the class-independent representation exceeds the representable
    limits of the target type.
gelf_getsym() returns the value of argument
  sym if successful, or NULL in case of an error. Function
  gelf_update_sym() returns a non-zero value if
  successful, or zero in case of an error.
