RESTOREPOINTINFOA

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 80 バイト / x86: 80 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

フィールド型サイズx64x86説明
dwEventTypeRESTOREPOINTINFO_EVENT_TYPE4+0+0復元イベントの種別。RESTOREPOINTINFO_EVENT_TYPEで表す。
dwRestorePtTypeRESTOREPOINTINFO_TYPE4+4+4復元ポイントの種別。RESTOREPOINTINFO_TYPEで表す。
llSequenceNumberLONGLONG8+8+8復元ポイントのシーケンス番号。LONGLONGで表す。
szDescriptionCHAR64+16+16復元ポイントの説明。ANSI(CHAR)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)
; RESTOREPOINTINFOA サイズ: 80 バイト(x64)
dim st, 20    ; 4byte整数×20(構造体サイズ 80 / 4 切り上げ)
; dwEventType : RESTOREPOINTINFO_EVENT_TYPE (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; dwRestorePtType : RESTOREPOINTINFO_TYPE (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; llSequenceNumber : 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
; szDescription : CHAR (+16, 64byte)  varptr(st)+16 を基点に操作(64byte: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。
