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)
; NABTS_BUFFER サイズ: 543 バイト(x64)
dim st, 136    ; 4byte整数×136(構造体サイズ 543 / 4 切り上げ)
; ScanlinesRequested : VBICODECFILTERING_SCANLINES (+0, 128byte)  varptr(st)+0 を基点に操作(128byte:入れ子/配列)
; PictureNumber : LONGLONG (+128, 8byte)  qpoke st,128,値 / qpeek(st,128)  ※IronHSPのみ。3.7/3.8は lpoke st,128,下位 : lpoke st,132,上位
; NabtsLines : NABTS_BUFFER_LINE (+136, 407byte)  varptr(st)+136 を基点に操作(407byte: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。
; ※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)。
