PARTITION_INFORMATION

構造体

サイズx64: 32 バイト / x86: 32 バイト

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
StartingOffset	LONGLONG	8	+0	+0	パーティションの開始オフセット。バイト単位。
PartitionLength	LONGLONG	8	+8	+8	パーティションの長さ。バイト単位。
HiddenSectors	DWORD	4	+16	+16	パーティション前方の隠しセクタ数。
PartitionNumber	DWORD	4	+20	+20	パーティション番号。1始まり。
PartitionType	BYTE	1	+24	+24	パーティション種別を示すMBRタイプコード。
BootIndicator	BOOLEAN	1	+25	+25	ブート可能パーティションかどうかを示す真偽値。
RecognizedPartition	BOOLEAN	1	+26	+26	OSが認識可能なパーティションかどうかを示す真偽値。
RewritePartition	BOOLEAN	1	+27	+27	パーティションテーブルを書き換えるかどうかを示す真偽値。

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)
; PARTITION_INFORMATION サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; StartingOffset : LONGLONG (+0, 8byte)  qpoke st,0,値 / qpeek(st,0)  ※IronHSPのみ。3.7/3.8は lpoke st,0,下位 : lpoke st,4,上位
; PartitionLength : LONGLONG (+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
; HiddenSectors : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; PartitionNumber : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; PartitionType : BYTE (+24, 1byte)  poke st,24,値  /  値 = peek(st,24)
; BootIndicator : BOOLEAN (+25, 1byte)  poke st,25,値  /  値 = peek(st,25)
; RecognizedPartition : BOOLEAN (+26, 1byte)  poke st,26,値  /  値 = peek(st,26)
; RewritePartition : BOOLEAN (+27, 1byte)  poke st,27,値  /  値 = peek(st,27)
; ※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。
