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)
; KSJACK_SINK_INFORMATION サイズ: 96 バイト(x64)
dim st, 24    ; 4byte整数×24(構造体サイズ 96 / 4 切り上げ)
; ConnType : KSJACK_SINK_CONNECTIONTYPE (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; ManufacturerId : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; ProductId : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; AudioLatency : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; HDCPCapable : BOOL (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; AICapable : BOOL (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; SinkDescriptionLength : BYTE (+20, 1byte)  poke st,20,値  /  値 = peek(st,20)
; SinkDescription : WCHAR (+22, 64byte)  varptr(st)+22 を基点に操作(64byte:入れ子/配列)
; PortId : LUID (+88, 8byte)  varptr(st)+88 を基点に操作(8byte: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)。
