MIB_IPPATH_TABLE

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 160 バイト / x86: 144 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
NumEntriesDWORD4+0+0Table配列に格納されたパスエントリの数を示す。
TableMIB_IPPATH_ROW152/136+8+8IPパス行(MIB_IPPATH_ROW)の可変長配列である。
