SIPAEVENT_SI_POLICY_SIGNER_PAYLOAD

構造体
サイズx64: 17 バイト / x86: 17 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)。

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)
; SIPAEVENT_SI_POLICY_SIGNER_PAYLOAD サイズ: 17 バイト(x64)
dim st, 5    ; 4byte整数×5(構造体サイズ 17 / 4 切り上げ)
; RootID : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; CertificatesLength : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; CertificatesCount : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; PolicyNameLength : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; EKUsLength : WORD (+12, 2byte)  wpoke st,12,値  /  値 = wpeek(st,12)
; EKUsCount : WORD (+14, 2byte)  wpoke st,14,値  /  値 = wpeek(st,14)
; VarLengthData : BYTE (+16, 1byte)  varptr(st)+16 を基点に操作(1byte: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。
