        This call is intended to force the datasource to flush any pending

        would not normally have any effect on read-only datasources.

        Some data sources do not implement this method, and will still return

        The default implementation of this method just calls the SyncToDisk()
        method on each of the layers. Conceptionally, calling SyncToDisk() on
        a datasource should include any work that might be accomplished by
        calling SyncToDisk() on layers in that data source.

        This method allows positioning of a layer such that the

        This call is intended to force the layer to flush any pending writes

        OGR_L_SetIgnoredFields(OGRLayerH hLayer, const char **papszFields)

        Set which fields can be omitted when retrieving features from the
        layer.

        If the driver supports this functionality (testable using
        OLCIgnoreFields capability), it will not fetch the specified fields in
        subsequent calls to GetFeature() / GetNextFeature() and thus save some
        processing time and/or bandwidth.

        Besides field names of the layers, the following special fields can be
        passed: "OGR_GEOMETRY" to ignore geometry and "OGR_STYLE" to
        ignore layer style.

        By default, no fields are ignored.

        This method is the same as the C++ method OGRLayer::SetIgnoredFields()

        Parameters:
        -----------

        papszFields:  an array of field names terminated by NULL item. If NULL
        is passed, the ignored list is cleared.

        OGRERR_NONE if all field names have been resolved (even if the driver
        does not support this method)
