DOT11_IBSS_PARAMS

構造体
サイズx64: 16 バイト / x86: 16 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)。

フィールド

フィールド型サイズx64x86説明
HeaderNDIS_OBJECT_HEADER4+0+0NDIS オブジェクトのバージョン情報を含むヘッダー。
bJoinOnlyBOOLEAN1+4+4既存 IBSS への参加のみを行うか示すフラグ。
uIEsOffsetDWORD4+8+8情報要素データへの先頭からのオフセット。
uIEsLengthDWORD4+12+12情報要素データのバイト長を表す。

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_IBSS_PARAMS 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)
; Header : NDIS_OBJECT_HEADER (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; bJoinOnly : BOOLEAN (+4, 1byte)  poke st,4,値  /  値 = peek(st,4)
; uIEsOffset : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; uIEsLength : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; ※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)。
