サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド	型	サイズ	x64	x86	説明
InterfaceNumber	BYTE	1	+0	+0	このクラスインターフェイスの番号を示す。
PipeCount	BYTE	1	+1	+1	このインターフェイスのパイプ数を示す。
PipeArr	USBFN_PIPE_INFORMATION	192	+4	+4	各パイプ情報を格納するUSBFN_PIPE_INFORMATION配列。

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)
; USBFN_CLASS_INTERFACE サイズ: 196 バイト(x64)
dim st, 49    ; 4byte整数×49(構造体サイズ 196 / 4 切り上げ)
; InterfaceNumber : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; PipeCount : BYTE (+1, 1byte)  poke st,1,値  /  値 = peek(st,1)
; PipeArr : USBFN_PIPE_INFORMATION (+4, 192byte)  varptr(st)+4 を基点に操作(192byte: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)。
