MIB_IPDESTROW

構造体

サイズx64: 64 バイト / x86: 64 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	x64	x86	説明
ForwardRow	MIB_IPFORWARDROW	56	+0	+0	宛先ルートの転送情報を保持するMIB_IPFORWARDROW構造体である。
dwForwardPreference	DWORD	4	+56	+56	このルートの優先度(プリファレンス値)を示す。
dwForwardViewSet	DWORD	4	+60	+60	このルートが属するビューの集合を示すビットマスクである。

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)
; MIB_IPDESTROW サイズ: 64 バイト(x64)
dim st, 16    ; 4byte整数×16(構造体サイズ 64 / 4 切り上げ)
; ForwardRow : MIB_IPFORWARDROW (+0, 56byte)  varptr(st)+0 を基点に操作(56byte:入れ子/配列)
; dwForwardPreference : DWORD (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; dwForwardViewSet : DWORD (+60, 4byte)  st.15 = 値  /  値 = st.15   (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。
