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)
; D3D12_FEATURE_DATA_VIDEO_DECODER_HEAP_SIZE1 サイズ: 80 バイト(x64)
dim st, 20    ; 4byte整数×20(構造体サイズ 80 / 4 切り上げ)
; VideoDecoderHeapDesc : D3D12_VIDEO_DECODER_HEAP_DESC (+0, 56byte)  varptr(st)+0 を基点に操作(56byte:入れ子/配列)
; Protected : BOOL (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; MemoryPoolL0Size : ULONGLONG (+64, 8byte)  qpoke st,64,値 / qpeek(st,64)  ※IronHSPのみ。3.7/3.8は lpoke st,64,下位 : lpoke st,68,上位
; MemoryPoolL1Size : ULONGLONG (+72, 8byte)  qpoke st,72,値 / qpeek(st,72)  ※IronHSPのみ。3.7/3.8は lpoke st,72,下位 : lpoke st,76,上位
; ※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。
