DXGI_OUTPUT_DESC
構造体サイズ=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 |
|---|---|---|---|---|---|
| DeviceName | WCHAR | 64 | +0 | +0 | 出力(モニター)のデバイス名を表すワイド文字列。 |
| DesktopCoordinates | RECT | 16 | +64 | +64 | 仮想デスクトップ座標系における出力の矩形。 |
| AttachedToDesktop | BOOL | 4 | +80 | +80 | 出力がデスクトップに接続されているかを示すブール値。 |
| Rotation | DXGI_MODE_ROTATION | 4 | +84 | +84 | ディスプレイの回転状態を示す列挙値。 |
| Monitor | HMONITOR | 8/4 | +88 | +88 | この出力に対応するモニターのHMONITORハンドル。 |

}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。(x86 レイアウト)
; DXGI_OUTPUT_DESC サイズ: 92 バイト(x86)
dim st, 23 ; 4byte整数×23(構造体サイズ 92 / 4 切り上げ)
; DeviceName : WCHAR (+0, 64byte) varptr(st)+0 を基点に操作(64byte:入れ子/配列)
; DesktopCoordinates : RECT (+64, 16byte) varptr(st)+64 を基点に操作(16byte:入れ子/配列)
; AttachedToDesktop : BOOL (+80, 4byte) st.20 = 値 / 値 = st.20 (lpoke/lpeek も可)
; Rotation : DXGI_MODE_ROTATION (+84, 4byte) st.21 = 値 / 値 = st.21 (lpoke/lpeek も可)
; Monitor : HMONITOR (+88, 4byte) st.22 = 値 / 値 = st.22 (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。; 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)
