パラメーター

名前型方向説明
dwFlagsDWORDin取得対象を示すフラグ。GPO_LIST_FLAG_MACHINEでマシン、未指定でユーザーを対象とする。
pMachineNameLPCSTRinoptional対象コンピューター名(ANSI)。NULL可でローカルを使う。
pSidUserPSIDinoptional対象ユーザーのSID。マシン側取得時はNULL可。
pGuidExtensionGUID*in適用結果を取得するCSE(クライアント側拡張)のGUID。
ppGPOListGROUP_POLICY_OBJECTA**out適用されたGPOの連結リスト(GROUP_POLICY_OBJECTA)を受け取る出力ポインタ。
