VDS_PARTITION_INFORMATION_EX
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
| フィールド | 型 | サイズ | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| dwPartitionStyle | __VDS_PARTITION_STYLE | 4 | +0 | +0 | パーティション形式を示す__VDS_PARTITION_STYLE列挙値。 |
| ullStartingOffset | ULONGLONG | 8 | +8 | +8 | パーティションの開始オフセットをバイト単位で示す。 |
| ullPartitionLength | ULONGLONG | 8 | +16 | +16 | パーティションの長さをバイト単位で示す。 |
| dwPartitionNumber | DWORD | 4 | +24 | +24 | パーティション番号(1始まり)。 |
| bRewritePartition | BOOLEAN | 1 | +28 | +28 | パーティションエントリを書き換えるか否かを示すBOOLEAN値。 |
| Anonymous | _Anonymous_e__Union | 112 | +32 | +32 | 形式に応じたMBR/GPT固有情報を格納する無名共用体。 |
共用体: _Anonymous_e__Union x64 112B / x86 112B

}HSP用 定義
HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; VDS_PARTITION_INFORMATION_EX サイズ: 144 バイト(x64)
dim st, 36 ; 4byte整数×36(構造体サイズ 144 / 4 切り上げ)
; dwPartitionStyle : __VDS_PARTITION_STYLE (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; ullStartingOffset : ULONGLONG (+8, 8byte) qpoke st,8,値 / qpeek(st,8) ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; ullPartitionLength : ULONGLONG (+16, 8byte) qpoke st,16,値 / qpeek(st,16) ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; dwPartitionNumber : DWORD (+24, 4byte) st.6 = 値 / 値 = st.6 (lpoke/lpeek も可)
; bRewritePartition : BOOLEAN (+28, 1byte) poke st,28,値 / 値 = peek(st,28)
; Anonymous : _Anonymous_e__Union (+32, 112byte) varptr(st)+32 を基点に操作(112byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
