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)
; WTS_TIME_ZONE_INFORMATION サイズ: 172 バイト(x64)
dim st, 43    ; 4byte整数×43(構造体サイズ 172 / 4 切り上げ)
; Bias : INT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; StandardName : WCHAR (+4, 64byte)  varptr(st)+4 を基点に操作(64byte:入れ子/配列)
; StandardDate : WTS_SYSTEMTIME (+68, 16byte)  varptr(st)+68 を基点に操作(16byte:入れ子/配列)
; StandardBias : INT (+84, 4byte)  st.21 = 値  /  値 = st.21   (lpoke/lpeek も可)
; DaylightName : WCHAR (+88, 64byte)  varptr(st)+88 を基点に操作(64byte:入れ子/配列)
; DaylightDate : WTS_SYSTEMTIME (+152, 16byte)  varptr(st)+152 を基点に操作(16byte:入れ子/配列)
; DaylightBias : INT (+168, 4byte)  st.42 = 値  /  値 = st.42   (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。
; ※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)。
