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_VideoAttributes サイズ: 52 バイト(x64)
dim st, 13    ; 4byte整数×13(構造体サイズ 52 / 4 切り上げ)
; fPanscanPermitted : BOOL (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; fLetterboxPermitted : BOOL (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; ulAspectX : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; ulAspectY : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; ulFrameRate : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; ulFrameHeight : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; Compression : DVD_VIDEO_COMPRESSION (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; fLine21Field1InGOP : BOOL (+28, 4byte)  st.7 = 値  /  値 = st.7   (lpoke/lpeek も可)
; fLine21Field2InGOP : BOOL (+32, 4byte)  st.8 = 値  /  値 = st.8   (lpoke/lpeek も可)
; ulSourceResolutionX : DWORD (+36, 4byte)  st.9 = 値  /  値 = st.9   (lpoke/lpeek も可)
; ulSourceResolutionY : DWORD (+40, 4byte)  st.10 = 値  /  値 = st.10   (lpoke/lpeek も可)
; fIsSourceLetterboxed : BOOL (+44, 4byte)  st.11 = 値  /  値 = st.11   (lpoke/lpeek も可)
; fIsFilmMode : BOOL (+48, 4byte)  st.12 = 値  /  値 = st.12   (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。
