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)
; MIXERCAPS2A 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)
; wMid : WORD (+0, 2byte)  wpoke st,0,値  /  値 = wpeek(st,0)
; wPid : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; vDriverVersion : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; szPname : CHAR (+8, 32byte)  varptr(st)+8 を基点に操作(32byte:入れ子/配列)
; fdwSupport : DWORD (+40, 4byte)  st.10 = 値  /  値 = st.10   (lpoke/lpeek も可)
; cDestinations : DWORD (+44, 4byte)  st.11 = 値  /  値 = st.11   (lpoke/lpeek も可)
; ManufacturerGuid : GUID (+48, 16byte)  varptr(st)+48 を基点に操作(16byte:入れ子/配列)
; ProductGuid : GUID (+64, 16byte)  varptr(st)+64 を基点に操作(16byte:入れ子/配列)
; NameGuid : GUID (+80, 16byte)  varptr(st)+80 を基点に操作(16byte: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)。
