Return a pointer to the value at index contained in this.
*Note*: in binding languages, some custom types fail to be correctly passed through. For these types, you should use specific functions. For instance, in the Python binding, a [type@ColorArray] `GValue` won't be usable with this function. You should use instead [ method@ValueArray.get_color_array].
