VDS_PATH_POLICY

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 24 バイト / x86: 24 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

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)
; VDS_PATH_POLICY サイズ: 24 バイト(x64)
dim st, 6    ; 4byte整数×6(構造体サイズ 24 / 4 切り上げ)
; pathId : VDS_PATH_ID (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; bPrimaryPath : BOOL (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; ulWeight : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (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)。
#defstruct global VDS_PATH_ID
    #field int64 ullSourceId
    #field int64 ullPathId
#endstruct

#defstruct global VDS_PATH_POLICY
    #field VDS_PATH_ID pathId
    #field bool bPrimaryPath
    #field int ulWeight
#endstruct

stdim st, VDS_PATH_POLICY        ; NSTRUCT 変数を確保
st->bPrimaryPath = 100
