RESTOREPOINTINFOEX

構造体
サイズx64: 532 バイト / x86: 532 バイトパッキング1

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

dwEventTypeDWORD4+8+8復元イベントの種別を示す値。
dwRestorePtTypeDWORD4+12+12復元ポイントの種別を示す値。
dwRPNumDWORD4+16+16復元ポイント番号。
szDescriptionWCHAR512+20+20復元ポイントの説明。WCHARの固定長バッファ。

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)
; RESTOREPOINTINFOEX サイズ: 532 バイト(x64)
dim st, 133    ; 4byte整数×133(構造体サイズ 532 / 4 切り上げ)
; ftCreation : FILETIME (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; dwEventType : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; dwRestorePtType : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; dwRPNum : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; szDescription : WCHAR (+20, 512byte)  varptr(st)+20 を基点に操作(512byte: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。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
