SOCKET_PROCESSOR_AFFINITY

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 8 バイト / x86: 8 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
ProcessorPROCESSOR_NUMBER4+0+0ソケット処理を割り当てるプロセッサ番号(グループ+番号)である。
NumaNodeIdWORD2+4+4関連付けるNUMAノードのIDである。
ReservedWORD2+6+6予約フィールドである。0を設定する。

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)
; SOCKET_PROCESSOR_AFFINITY サイズ: 8 バイト(x64)
dim st, 2    ; 4byte整数×2(構造体サイズ 8 / 4 切り上げ)
; Processor : PROCESSOR_NUMBER (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; NumaNodeId : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; Reserved : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; ※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)。
#defstruct global PROCESSOR_NUMBER
    #field short Group
    #field byte Number
    #field byte Reserved
#endstruct

#defstruct global SOCKET_PROCESSOR_AFFINITY
    #field PROCESSOR_NUMBER Processor
    #field short NumaNodeId
    #field short Reserved
#endstruct

stdim st, SOCKET_PROCESSOR_AFFINITY        ; NSTRUCT 変数を確保
st->NumaNodeId = 100
