DEVPRIVATE_RESOURCE

構造体

サイズx64: 36 バイト / x86: 36 バイトパッキング1

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
PRV_Header	DEVPRIVATE_DES	24	+0	+0	私的リソースの記述子ヘッダ(DEVPRIVATE_DES)。
PRV_Data	DEVPRIVATE_RANGE	12	+24	+24	私的範囲データの先頭(DEVPRIVATE_RANGE)。可変長配列の起点。

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)
; DEVPRIVATE_RESOURCE サイズ: 36 バイト(x64)
dim st, 9    ; 4byte整数×9(構造体サイズ 36 / 4 切り上げ)
; PRV_Header : DEVPRIVATE_DES (+0, 24byte)  varptr(st)+0 を基点に操作(24byte:入れ子/配列)
; PRV_Data : DEVPRIVATE_RANGE (+24, 12byte)  varptr(st)+24 を基点に操作(12byte: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。
; ※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)。
