Expand description

DEPRECATION NOTICE**: This method is scheduled for removal in a future release.

Fetch an internal arrow struct array from the arrow result. Remember to call release on the respective ArrowArray object.

This function can be called multiple time to get next chunks, which will free the previous out_array. So consume the out_array before calling this function again.

@param result The result to fetch the array from. @param out_array The output array. @return DuckDBSuccess on success or DuckDBError on failure.
