PF_FILTER_STATS

構造体

サイズx64: 72 バイト / x86: 48 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
dwNumPacketsFiltered	DWORD	4	+0	+0	このフィルタによってフィルタ処理されたパケット数である。
info	PF_FILTER_DESCRIPTOR	64/44	+8	+4	対応するフィルタの記述子(PF_FILTER_DESCRIPTOR)である。
