JET_RSTINFO_W
構造体サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。
フィールド

|---|---|---|---|---|---|
| cbStruct | DWORD | 4 | +0 | +0 | この構造体のバイトサイズ。 |
| rgrstmap | JET_RSTMAP_W* | 8/4 | +8 | +4 | データベースの再配置マップ配列JET_RSTMAP_Wへのポインタ。 |
| crstmap | INT | 4 | +16 | +8 | rgrstmap配列の要素数。 |
| lgposStop | JET_LGPOS | 8 | +20 | +12 | リカバリを停止するログ位置JET_LGPOS(時点復元用)。 |
| logtimeStop | JET_LOGTIME | 24/16 | +32 | +20 | リカバリを停止する時刻JET_LOGTIME(時点復元用)。 |
| pfnStatus | JET_PFNSTATUS | 8/4 | +56 | +36 | 進捗を通知するJET_PFNSTATUSコールバック関数ポインタ。NULL可。 |
