  dwarf_get_fde_instr_bytes(Dwarf_Fde
    fde, Dwarf_Ptr *ret_inst,
    Dwarf_Unsigned *ret_len, Dwarf_Error
    *error);
dwarf_get_fde_instr_bytes() retrieves
  instruction bytes from a given FDE descriptor.
Argument fde should reference a valid DWARF FDE descriptor.
Argument ret_inst should point to a location that will be set to a pointer to an array of bytes containing the instructions of the FDE descriptor.
Argument ret_len should point to a location that will hold the length in bytes of the instructions returned in argument ret_inst.
If argument err is not
    NULL, it will be used to store error information in
    case of an error.
Applications can use the function dwarf_expand_frame_instructions(3) to parse and expand the returned instruction bytes into an array of Dwarf_Frame_Op descriptors.
dwarf_get_fde_instr_bytes() returns
  DW_DLV_OK when it succeeds. In case of an error, it
  returns DW_DLV_ERROR and sets the argument
  err.
dwarf_get_fde_instr_bytes() can fail with:
