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)
; SpanningEventEmmMessage サイズ: 18 バイト(x64)
dim st, 5    ; 4byte整数×5(構造体サイズ 18 / 4 切り上げ)
; bCAbroadcasterGroupId : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; bMessageControl : BYTE (+1, 1byte)  poke st,1,値  /  値 = peek(st,1)
; wServiceId : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; wTableIdExtension : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; bDeletionStatus : BYTE (+6, 1byte)  poke st,6,値  /  値 = peek(st,6)
; bDisplayingDuration1 : BYTE (+7, 1byte)  poke st,7,値  /  値 = peek(st,7)
; bDisplayingDuration2 : BYTE (+8, 1byte)  poke st,8,値  /  値 = peek(st,8)
; bDisplayingDuration3 : BYTE (+9, 1byte)  poke st,9,値  /  値 = peek(st,9)
; bDisplayingCycle : BYTE (+10, 1byte)  poke st,10,値  /  値 = peek(st,10)

; wMessageLength : WORD (+14, 2byte)  wpoke st,14,値  /  値 = wpeek(st,14)
; szMessageArea : WCHAR (+16, 2byte)  varptr(st)+16 を基点に操作(2byte: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。
