MIB_IPMCAST_BOUNDARY_TABLE
構造体サイズ=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配列に格納されたマルチキャスト境界エントリの数を示す。 |
| table | MIB_IPMCAST_BOUNDARY | 16 | +4 | +4 | マルチキャスト境界行(MIB_IPMCAST_BOUNDARY)の可変長配列である。 |

}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_IPMCAST_BOUNDARY_TABLE サイズ: 20 バイト(x64)
dim st, 5 ; 4byte整数×5(構造体サイズ 20 / 4 切り上げ)
; dwNumEntries : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; table : MIB_IPMCAST_BOUNDARY (+4, 16byte) varptr(st)+4 を基点に操作(16byte: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)。
