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)
; DVD_TitleAttributes サイズ: 3208 バイト(x64)
dim st, 802    ; 4byte整数×802(構造体サイズ 3208 / 4 切り上げ)
; Anonymous : _Anonymous_e__Union (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; VideoAttributes : DVD_VideoAttributes (+4, 52byte)  varptr(st)+4 を基点に操作(52byte:入れ子/配列)
; ulNumberOfAudioStreams : DWORD (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; AudioAttributes : DVD_AudioAttributes (+60, 320byte)  varptr(st)+60 を基点に操作(320byte:入れ子/配列)
; MultichannelAudioAttributes : DVD_MultichannelAudioAttributes (+384, 2304byte)  varptr(st)+384 を基点に操作(2304byte:入れ子/配列)
; ulNumberOfSubpictureStreams : DWORD (+2688, 4byte)  st.672 = 値  /  値 = st.672   (lpoke/lpeek も可)
; SubpictureAttributes : DVD_SubpictureAttributes (+2692, 512byte)  varptr(st)+2692 を基点に操作(512byte: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。
