SE_SID
共用体サイズ=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 |
|---|---|---|---|---|---|
| Sid | SID | 12 | +0 | +0 | SID構造体としての表現。 |
| Buffer | BYTE | 68 | +0 | +0 | 最大サイズのSIDを格納するための固定長バイトバッファ。 |

}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)
; SE_SID サイズ: 68 バイト(x64)
dim st, 17 ; 4byte整数×17(構造体サイズ 68 / 4 切り上げ)
; Sid : SID (+0, 12byte) varptr(st)+0 を基点に操作(12byte:入れ子/配列)
; Buffer : BYTE (+0, 68byte) varptr(st)+0 を基点に操作(68byte: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)。
