OPM_REQUESTED_INFORMATION
構造体サイズ=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 |
|---|---|---|---|---|---|
| omac | OPM_OMAC | 16 | +0 | +0 | 返却情報の完全性を検証するOMAC署名(OPM_OMAC)。 |
| cbRequestedInformationSize | DWORD | 4 | +16 | +16 | abRequestedInformation内の有効データのバイトサイズ。 |
| abRequestedInformation | BYTE | 4076 | +20 | +20 | 要求された情報の本体を格納するバイト配列。 |

}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)
; OPM_REQUESTED_INFORMATION サイズ: 4096 バイト(x64)
dim st, 1024 ; 4byte整数×1024(構造体サイズ 4096 / 4 切り上げ)
; omac : OPM_OMAC (+0, 16byte) varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; cbRequestedInformationSize : DWORD (+16, 4byte) st.4 = 値 / 値 = st.4 (lpoke/lpeek も可)
; abRequestedInformation : BYTE (+20, 4076byte) varptr(st)+20 を基点に操作(4076byte: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)。
