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)
; USB_HUB_DEVICE_INFO サイズ: 103 バイト(x64)
dim st, 26    ; 4byte整数×26(構造体サイズ 103 / 4 切り上げ)
; HubDescriptor : USB_HUB_DESCRIPTOR (+0, 71byte)  varptr(st)+0 を基点に操作(71byte:入れ子/配列)
; HubNumber : DWORD (+71, 4byte)  lpoke st,71,値  /  値 = lpeek(st,71)
; DeviceAddress : WORD (+75, 2byte)  wpoke st,75,値  /  値 = wpeek(st,75)
; HubIsSelfPowered : BOOLEAN (+77, 1byte)  poke st,77,値  /  値 = peek(st,77)
; HubIsRootHub : BOOLEAN (+78, 1byte)  poke st,78,値  /  値 = peek(st,78)
; HubCapabilities : USB_HUB_CAPABILITIES (+79, 4byte)  varptr(st)+79 を基点に操作(4byte:入れ子/配列)
; NumberOfHubPorts : DWORD (+83, 4byte)  lpoke st,83,値  /  値 = lpeek(st,83)
; PortInfo : USB_HUB_PORT_INFORMATION (+87, 16byte)  varptr(st)+87 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)。
