EssPartitionGetList

現在選択されているデータベースが関与しているパーティション定義のリストを戻します。

構文

            ESS_FUNC_M EssPartitionGetList (
            hCtx, pSelectPartition, pusCount, ppPartition
            );

パラメータ	データ型	説明
hCtx	ESS_HCTX_T	APIコンテキスト・ハンドル。
pSelectPartition	ESS_PARTSLCT_T	パーティションの選択条件。
pusCount	ESS_PUSHORT_T	戻されるパーティションの数。
ppPartition	ESS_PART_INFO_T	パーティション情報構造体において割り当てられた配列へのポインタ。

戻り値

正常終了の場合は0が戻され、失敗した場合はエラー・コードが戻されます。
