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_SBCP_INFO_PAYLOAD_V1 サイズ: 21 バイト(x64)
dim st, 6    ; 4byte整数×6(構造体サイズ 21 / 4 切り上げ)
; PayloadVersion : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; VarDataOffset : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; HashAlgID : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; DigestLength : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; Options : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; SignersCount : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; VarData : BYTE (+20, 1byte)  varptr(st)+20 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。
