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_NODE_CONNECTION_INFORMATION サイズ: 46 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 46 / 4 切り上げ)
; ConnectionIndex : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; DeviceDescriptor : USB_DEVICE_DESCRIPTOR (+4, 18byte)  varptr(st)+4 を基点に操作(18byte:入れ子/配列)
; CurrentConfigurationValue : BYTE (+22, 1byte)  poke st,22,値  /  値 = peek(st,22)
; LowSpeed : BOOLEAN (+23, 1byte)  poke st,23,値  /  値 = peek(st,23)
; DeviceIsHub : BOOLEAN (+24, 1byte)  poke st,24,値  /  値 = peek(st,24)
; DeviceAddress : WORD (+25, 2byte)  wpoke st,25,値  /  値 = wpeek(st,25)
; NumberOfOpenPipes : DWORD (+27, 4byte)  lpoke st,27,値  /  値 = lpeek(st,27)
; ConnectionStatus : USB_CONNECTION_STATUS (+31, 4byte)  lpoke st,31,値  /  値 = lpeek(st,31)
; PipeList : USB_PIPE_INFO (+35, 11byte)  varptr(st)+35 を基点に操作(11byte: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)。
