フィールド	型	サイズ	x64	x86	説明
Version	DWORD	4	+0	+0	構造体のバージョン番号。
Size	DWORD	4	+4	+4	この構造体のサイズをバイト単位で示す。
ProtocolSpecificData	STORAGE_PROTOCOL_SPECIFIC_DATA	40	+8	+8	プロトコル固有データを保持するSTORAGE_PROTOCOL_SPECIFIC_DATA構造体。

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)
; STORAGE_PROTOCOL_DATA_DESCRIPTOR サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; Version : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Size : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; ProtocolSpecificData : STORAGE_PROTOCOL_SPECIFIC_DATA (+8, 40byte)  varptr(st)+8 を基点に操作(40byte: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)。
