NDIS_RECEIVE_SCALE_CAPABILITIES

構造体
サイズx64: 16 バイト / x86: 16 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
HeaderNDIS_OBJECT_HEADER4+0+0構造体の型・リビジョン・サイズを示すNDISオブジェクトヘッダー。
CapabilitiesFlagsDWORD4+4+4RSSの能力を示すフラグ(ハッシュ種別やトープロジ等)。
NumberOfInterruptMessagesDWORD4+8+8サポートする割り込みメッセージ数。
NumberOfReceiveQueuesDWORD4+12+12サポートする受信キュー数。

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)
; NDIS_RECEIVE_SCALE_CAPABILITIES サイズ: 16 バイト(x64)
dim st, 4    ; 4byte整数×4(構造体サイズ 16 / 4 切り上げ)
; Header : NDIS_OBJECT_HEADER (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; CapabilitiesFlags : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; NumberOfInterruptMessages : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; NumberOfReceiveQueues : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (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。
; ※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)。
