D3DX11_FFT_BUFFER_INFO

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 40 バイト / x86: 40 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x64x86説明
NumTempBufferSizesDWORD4+0+0必要な一時バッファの数。
TempBufferFloatSizesDWORD16+4+4各一時バッファのサイズ(float単位)を格納する配列。
NumPrecomputeBufferSizesDWORD4+20+20必要な事前計算バッファの数。
PrecomputeBufferFloatSizesDWORD16+24+24各事前計算バッファのサイズ(float単位)を格納する配列。

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)
; D3DX11_FFT_BUFFER_INFO 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)
; NumTempBufferSizes : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; TempBufferFloatSizes : DWORD (+4, 16byte)  varptr(st)+4 を基点に操作(16byte:入れ子/配列)
; NumPrecomputeBufferSizes : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; PrecomputeBufferFloatSizes : DWORD (+24, 16byte)  varptr(st)+24 を基点に操作(16byte: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。
