DXGI_FRAME_STATISTICS_MEDIA
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 |
|---|---|---|---|---|---|
| PresentCount | DWORD | 4 | +0 | +0 | アプリが呼び出したPresentの累積回数。 |
| PresentRefreshCount | DWORD | 4 | +4 | +4 | Present時点のリフレッシュ累積回数。 |
| SyncRefreshCount | DWORD | 4 | +8 | +8 | QPC時刻取得時のリフレッシュ累積回数。 |
| SyncQPCTime | LONGLONG | 8 | +16 | +16 | 直近のVBlankに対応する高精度カウンタ(QPC)時刻。 |
| SyncGPUTime | LONGLONG | 8 | +24 | +24 | 予約済みで通常0が返るGPU時刻フィールド。 |
| CompositionMode | DXGI_FRAME_PRESENTATION_MODE | 4 | +32 | +32 | メディアフレームの合成(プレゼンテーション)モードを示す列挙値。 |
| ApprovedPresentDuration | DWORD | 4 | +36 | +36 | 承認されたPresentの表示継続時間(100ナノ秒単位)。 |

}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_FRAME_STATISTICS_MEDIA サイズ: 40 バイト(x64)
dim st, 10 ; 4byte整数×10(構造体サイズ 40 / 4 切り上げ)
; PresentCount : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; PresentRefreshCount : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; SyncRefreshCount : DWORD (+8, 4byte) st.2 = 値 / 値 = st.2 (lpoke/lpeek も可)
; SyncQPCTime : LONGLONG (+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
; SyncGPUTime : LONGLONG (+24, 8byte) qpoke st,24,値 / qpeek(st,24) ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,上位
; CompositionMode : DXGI_FRAME_PRESENTATION_MODE (+32, 4byte) st.8 = 値 / 値 = st.8 (lpoke/lpeek も可)
; ApprovedPresentDuration : DWORD (+36, 4byte) st.9 = 値 / 値 = st.9 (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。
