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。(x86 レイアウト)
; ATM_PVC_PARAMS サイズ: 84 バイト(x86)
dim st, 21    ; 4byte整数×21(構造体サイズ 84 / 4 切り上げ)
; PvcConnectionId : ATM_CONNECTION_ID (+0, 12byte)  varptr(st)+0 を基点に操作(12byte:入れ子/配列)
; PvcQos : QOS (+12, 72byte)  varptr(st)+12 を基点に操作(72byte: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。
