WNODE_SINGLE_INSTANCE

構造体

サイズx64: 72 バイト / x86: 72 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	x64	x86	説明

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)
; WNODE_SINGLE_INSTANCE サイズ: 72 バイト(x64)
dim st, 18    ; 4byte整数×18(構造体サイズ 72 / 4 切り上げ)
; WnodeHeader : WNODE_HEADER (+0, 48byte)  varptr(st)+0 を基点に操作(48byte:入れ子/配列)
; OffsetInstanceName : DWORD (+48, 4byte)  st.12 = 値  /  値 = st.12   (lpoke/lpeek も可)
; InstanceIndex : DWORD (+52, 4byte)  st.13 = 値  /  値 = st.13   (lpoke/lpeek も可)
; DataBlockOffset : DWORD (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; SizeDataBlock : DWORD (+60, 4byte)  st.15 = 値  /  値 = st.15   (lpoke/lpeek も可)
; VariableData : BYTE (+64, 1byte)  varptr(st)+64 を基点に操作(1byte: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。
