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)
; DXGI_OUTDUPL_FRAME_INFO サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; LastPresentTime : LONGLONG (+0, 8byte)  qpoke st,0,値 / qpeek(st,0)  ※IronHSPのみ。3.7/3.8は lpoke st,0,下位 : lpoke st,4,上位
; LastMouseUpdateTime : 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
; AccumulatedFrames : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; RectsCoalesced : BOOL (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; ProtectedContentMaskedOut : BOOL (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; PointerPosition : DXGI_OUTDUPL_POINTER_POSITION (+28, 12byte)  varptr(st)+28 を基点に操作(12byte:入れ子/配列)
; TotalMetadataBufferSize : DWORD (+40, 4byte)  st.10 = 値  /  値 = st.10   (lpoke/lpeek も可)
; PointerShapeBufferSize : DWORD (+44, 4byte)  st.11 = 値  /  値 = st.11   (lpoke/lpeek も可)
; ※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)。
