L2TP_CONFIG_PARAMS1

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 48 バイト / x86: 36 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。(x86 レイアウト)
; L2TP_CONFIG_PARAMS1 サイズ: 36 バイト(x86)

; dwTunnelConfigParamFlags : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; TunnelConfigParams : L2TP_TUNNEL_CONFIG_PARAMS2 (+12, 24byte)  varptr(st)+12 を基点に操作(24byte: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。
