DXGI_OUTDUPL_DESC

構造体

サイズx64: 36 バイト / x86: 36 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)。

フィールド

フィールド	型	サイズ	x64	x86	説明
ModeDesc	DXGI_MODE_DESC	28	+0	+0	複製対象出力の表示モードを表すDXGI_MODE_DESC。
Rotation	DXGI_MODE_ROTATION	4	+28	+28	デスクトップ画像の回転状態を示す列挙値。

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_DESC サイズ: 36 バイト(x64)
dim st, 9    ; 4byte整数×9(構造体サイズ 36 / 4 切り上げ)
; ModeDesc : DXGI_MODE_DESC (+0, 28byte)  varptr(st)+0 を基点に操作(28byte:入れ子/配列)
; Rotation : DXGI_MODE_ROTATION (+28, 4byte)  st.7 = 値  /  値 = st.7   (lpoke/lpeek も可)
; DesktopImageInSystemMemory : BOOL (+32, 4byte)  st.8 = 値  /  値 = st.8   (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)。
