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)
; NTMS_PARTITIONINFORMATIONW サイズ: 960 バイト(x64)
dim st, 240    ; 4byte整数×240(構造体サイズ 960 / 4 切り上げ)
; PhysicalMedia : GUID (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; LogicalMedia : GUID (+16, 16byte)  varptr(st)+16 を基点に操作(16byte:入れ子/配列)
; State : DWORD (+32, 4byte)  st.8 = 値  /  値 = st.8   (lpoke/lpeek も可)
; Side : WORD (+36, 2byte)  wpoke st,36,値  /  値 = wpeek(st,36)
; dwOmidLabelIdLength : DWORD (+40, 4byte)  st.10 = 値  /  値 = st.10   (lpoke/lpeek も可)
; OmidLabelId : BYTE (+44, 255byte)  varptr(st)+44 を基点に操作(255byte:入れ子/配列)
; szOmidLabelType : WCHAR (+300, 128byte)  varptr(st)+300 を基点に操作(128byte:入れ子/配列)
; szOmidLabelInfo : WCHAR (+428, 512byte)  varptr(st)+428 を基点に操作(512byte:入れ子/配列)
; dwMountCount : DWORD (+940, 4byte)  st.235 = 値  /  値 = st.235   (lpoke/lpeek も可)

; Capacity : LONGLONG (+952, 8byte)  qpoke st,952,値 / qpeek(st,952)  ※IronHSPのみ。3.7/3.8は lpoke st,952,下位 : lpoke st,956,上位
; ※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。
