Function dwarf_whatattr() retrieves the attribute code
  for the DWARF attribute referenced by argument attr, and
  writes it to the location pointed to by argument
  retcode. If argument err is not
  NULL, it will be used to return an error descriptor in case of an error.
On success, function dwarf_whatattr() returns
  DW_DLV_OK. In case of an error, it returns
  DW_DLV_ERROR and sets argument
  err.
Function dwarf_whatattr() can fail with the following
  error:
  - [DW_DLE_ARGUMENT]
- Either of argument attr or
      retcode was NULL.
