This method is not directly available to language bindings.

#### Parameters

`idx`

  Type: `guint`

  Index.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

Type: `GRefString`

A `GRefString`, or `NULL` on error.

The returned data is owned by the instance.
