## Functions

### gog_series_check_validity ()

    void
    gog_series_check_validity (GogSeries *series);

Updates the is_valid flag for a series. This is an internal utility that should not really be necessary for general usage.

#### Parameters

series | GogSeries |

### gog_series_get_element ()

    GogSeriesElement *
    gog_series_get_element (GogSeries const *series,
