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_EX_V2 サイズ: 16 バイト(x64)
dim st, 4    ; 4byte整数×4(構造体サイズ 16 / 4 切り上げ)
; ConnectionIndex : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Length : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; SupportedUsbProtocols : USB_PROTOCOLS (+8, 4byte)  varptr(st)+8 を基点に操作(4byte:入れ子/配列)
; Flags : USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS (+12, 4byte)  varptr(st)+12 を基点に操作(4byte: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。
#defstruct global USB_NODE_CONNECTION_INFORMATION_EX_V2, pack=1

#endstruct

stdim st, USB_NODE_CONNECTION_INFORMATION_EX_V2        ; NSTRUCT 変数を確保
st->ConnectionIndex = 100
mes "ConnectionIndex=" + st->ConnectionIndex
; ※union フィールドは byte 列で確保(NSTRUCT は union 非対応)。必要に応じ手動でアクセス。
