MIB_IFTABLE

構造体

サイズx64: 864 バイト / x86: 864 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
dwNumEntries	DWORD	4	+0	+0	table配列に格納されたインターフェース行数を示す。
table	MIB_IFROW	860	+4	+4	MIB_IFROW要素を格納する可変長配列の先頭。

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_IFTABLE サイズ: 864 バイト(x64)
dim st, 216    ; 4byte整数×216(構造体サイズ 864 / 4 切り上げ)
; dwNumEntries : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; table : MIB_IFROW (+4, 860byte)  varptr(st)+4 を基点に操作(860byte: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。
