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)
; DOT11_CONNECTION_START_PARAMETERS サイズ: 52 バイト(x64)
dim st, 13    ; 4byte整数×13(構造体サイズ 52 / 4 切り上げ)
; Header : NDIS_OBJECT_HEADER (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; BSSType : DOT11_BSS_TYPE (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; AdhocBSSID : BYTE (+8, 6byte)  varptr(st)+8 を基点に操作(6byte:入れ子/配列)
; AdhocSSID : DOT11_SSID (+16, 36byte)  varptr(st)+16 を基点に操作(36byte: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)。
