構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 32 バイト / x86: 32 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

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)
; AM_DVD_RENDERSTATUS サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; hrVPEStatus : HRESULT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; bDvdVolInvalid : BOOL (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; bDvdVolUnknown : BOOL (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; bNoLine21In : BOOL (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; bNoLine21Out : BOOL (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; iNumStreams : INT (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; iNumStreamsFailed : INT (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; dwFailedStreamsFlag : DWORD (+28, 4byte)  st.7 = 値  /  値 = st.7   (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。
