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)
; SP_ALTPLATFORM_INFO_V2 サイズ: 28 バイト(x64)
dim st, 7    ; 4byte整数×7(構造体サイズ 28 / 4 切り上げ)
; cbSize : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Platform : VER_PLATFORM (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; MajorVersion : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; MinorVersion : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; ProcessorArchitecture : PROCESSOR_ARCHITECTURE (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; Anonymous : _Anonymous_e__Union (+18, 2byte)  varptr(st)+18 を基点に操作(2byte:入れ子/配列)
; FirstValidatedMajorVersion : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; FirstValidatedMinorVersion : DWORD (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; ※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。
