STORAGE_ZONE_DESCRIPTOR

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)。

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)
; STORAGE_ZONE_DESCRIPTOR 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)
; Size : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; ZoneType : STORAGE_ZONE_TYPES (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; ZoneCondition : STORAGE_ZONE_CONDITION (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; ResetWritePointerRecommend : BOOLEAN (+12, 1byte)  poke st,12,値  /  値 = peek(st,12)
; Reserved0 : BYTE (+13, 3byte)  varptr(st)+13 を基点に操作(3byte:入れ子/配列)
; ZoneSize : 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
; WritePointerOffset : ULONGLONG (+24, 8byte)  qpoke st,24,値 / qpeek(st,24)  ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,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。
