NDIS_WLAN_BSSID_EX

構造体
サイズx64: 120 バイト / x86: 120 バイト

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)。

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)
; NDIS_WLAN_BSSID_EX サイズ: 120 バイト(x64)
dim st, 30    ; 4byte整数×30(構造体サイズ 120 / 4 切り上げ)
; Length : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; MacAddress : BYTE (+4, 6byte)  varptr(st)+4 を基点に操作(6byte:入れ子/配列)
; Reserved : BYTE (+10, 2byte)  varptr(st)+10 を基点に操作(2byte:入れ子/配列)
; Ssid : NDIS_802_11_SSID (+12, 36byte)  varptr(st)+12 を基点に操作(36byte:入れ子/配列)
; Privacy : DWORD (+48, 4byte)  st.12 = 値  /  値 = st.12   (lpoke/lpeek も可)
; Rssi : INT (+52, 4byte)  st.13 = 値  /  値 = st.13   (lpoke/lpeek も可)
; NetworkTypeInUse : NDIS_802_11_NETWORK_TYPE (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; Configuration : NDIS_802_11_CONFIGURATION (+60, 32byte)  varptr(st)+60 を基点に操作(32byte:入れ子/配列)
; InfrastructureMode : NDIS_802_11_NETWORK_INFRASTRUCTURE (+92, 4byte)  st.23 = 値  /  値 = st.23   (lpoke/lpeek も可)
; SupportedRates : BYTE (+96, 16byte)  varptr(st)+96 を基点に操作(16byte:入れ子/配列)
; IELength : DWORD (+112, 4byte)  st.28 = 値  /  値 = st.28   (lpoke/lpeek も可)
; IEs : BYTE (+116, 1byte)  varptr(st)+116 を基点に操作(1byte: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)。
