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)
; BTH_QUERY_SERVICE サイズ: 256 バイト(x64)
dim st, 64    ; 4byte整数×64(構造体サイズ 256 / 4 切り上げ)
; type : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; serviceHandle : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; uuids : SdpQueryUuid (+8, 240byte)  varptr(st)+8 を基点に操作(240byte:入れ子/配列)
; numRange : DWORD (+248, 4byte)  st.62 = 値  /  値 = st.62   (lpoke/lpeek も可)
; pRange : SdpAttributeRange (+252, 4byte)  varptr(st)+252 を基点に操作(4byte: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)。
