NDIS_RECEIVE_SCALE_PARAMETERS

構造体

サイズx64: 28 バイト / x86: 28 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)。

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_PARAMETERS サイズ: 28 バイト(x64)
dim st, 7    ; 4byte整数×7(構造体サイズ 28 / 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)
; Flags : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; BaseCpuNumber : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; HashInformation : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; IndirectionTableSize : WORD (+12, 2byte)  wpoke st,12,値  /  値 = wpeek(st,12)
; IndirectionTableOffset : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; HashSecretKeySize : WORD (+20, 2byte)  wpoke st,20,値  /  値 = wpeek(st,20)
; HashSecretKeyOffset : DWORD (+24, 4byte)  st.6 = 値  /  値 = st.6   (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。
