構造体
📘 Microsoft Learn (日本語) · English

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)
; COMPOSITION_TARGET_STATS サイズ: 72 バイト(x64)
dim st, 18    ; 4byte整数×18(構造体サイズ 72 / 4 切り上げ)
; outstandingPresents : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; presentTime : ULONGLONG (+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
; vblankDuration : 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
; presentedStats : COMPOSITION_STATS (+24, 24byte)  varptr(st)+24 を基点に操作(24byte:入れ子/配列)
; completedStats : COMPOSITION_STATS (+48, 24byte)  varptr(st)+48 を基点に操作(24byte: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)。
