EXPLICIT_ACCESS_W

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 48 バイト / x86: 32 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
grfAccessPermissionsDWORD4+0+0付与または拒否するアクセス権のビットマスク。
grfAccessModeACCESS_MODE4+4+4アクセスの許可/拒否/監査等を示すACCESS_MODE値。
grfInheritanceACE_FLAGS4+8+8子オブジェクトへの継承方法を示すACE_FLAGSビット値。
TrusteeTRUSTEE_W32/20+16+12アクセス権が適用される対象トラスティ(Unicode)。

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。(x86 レイアウト)
; EXPLICIT_ACCESS_W サイズ: 32 バイト(x86)

; grfInheritance : ACE_FLAGS (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; Trustee : TRUSTEE_W (+12, 20byte)  varptr(st)+12 を基点に操作(20byte: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。
