PUBLIC_OBJECT_BASIC_INFORMATION

構造体
サイズx64: 56 バイト / x86: 56 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
AttributesDWORD4+0+0オブジェクトの属性を示すフラグ。
GrantedAccessDWORD4+4+4オブジェクトに対して付与されたアクセス権マスク。
HandleCountDWORD4+8+8オブジェクトを参照しているハンドル数。
PointerCountDWORD4+12+12オブジェクトへの参照(ポインタ)数。
ReservedDWORD40+16+16予約DWORD配列。

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)
; PUBLIC_OBJECT_BASIC_INFORMATION サイズ: 56 バイト(x64)
dim st, 14    ; 4byte整数×14(構造体サイズ 56 / 4 切り上げ)
; Attributes : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; GrantedAccess : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; HandleCount : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; PointerCount : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; Reserved : DWORD (+16, 40byte)  varptr(st)+16 を基点に操作(40byte: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。
