シグネチャ

// api-ms-win-security-base-l1-2-2.dll
#include <windows.h>

BOOL DeriveCapabilitySidsFromName(
    LPCWSTR CapName,
    PSID** CapabilityGroupSids,
    DWORD* CapabilityGroupSidCount,
    PSID** CapabilitySids,
    DWORD* CapabilitySidCount
);

パラメーター

名前	型	方向	説明
CapName	LPCWSTR	in	文字列形式のケイパビリティ名。
CapabilityGroupSids	PSID**	out	NTAuthority を持つ GroupSids。
CapabilityGroupSidCount	DWORD*	out	配列内の GroupSids の数。
CapabilitySids	PSID**	out	AppAuthority を持つ CapabilitySids。
CapabilitySidCount	DWORD*	out	AppAuthority を持つ CapabilitySid の数。

戻り値の型: BOOL

公式ドキュメント

この関数は、ケイパビリティ名から 2 つの SID 配列を構築します。1 つは NT Authority を持つグループ SID の配列で、もう 1 つは AppAuthority を持つケイパビリティ SID の配列です。

戻り値

関数が成功した場合は TRUE を返します。

関数が失敗した場合は FALSE を返します。拡張エラー情報を取得するには、GetLastError を呼び出してください。

解説(Remarks)

呼び出し元は、各配列で返される個々の SID を LocalFree を呼び出して解放するとともに、配列自体に割り当てられたメモリも解放する必要があります。

レガシーケイパビリティ(Win10 より前に公開されたもの)のアプリケーションケイパビリティ用に計算される SID は、公開済みの SID と同一になりますが、サービスグループケイパビリティ SID 用の SID はハッシュベースになります。
