構造体
📘 Microsoft Learn (日本語) · English

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_HEAP_DESC サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; SizeInBytes : ULONGLONG (+0, 8byte)  qpoke st,0,値 / qpeek(st,0)  ※IronHSPのみ。3.7/3.8は lpoke st,0,下位 : lpoke st,4,上位
; Properties : D3D12_HEAP_PROPERTIES (+8, 20byte)  varptr(st)+8 を基点に操作(20byte:入れ子/配列)
; Alignment : ULONGLONG (+32, 8byte)  qpoke st,32,値 / qpeek(st,32)  ※IronHSPのみ。3.7/3.8は lpoke st,32,下位 : lpoke st,36,上位
; Flags : D3D12_HEAP_FLAGS (+40, 4byte)  st.10 = 値  /  値 = st.10   (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)。
