パラメーター

名前	型	方向	説明
hServer	HANDLE	inoptional	対象RDセッションホストサーバーのハンドル。ローカルなら WTS_CURRENT_SERVER_HANDLE を指定する。
pReserved	void*	in	予約済みパラメーター。常に NULL を指定する。
Reserved	DWORD	in	予約済みパラメーター。常に 0 を指定する。
pListenerName	LPSTR	in	セキュリティ情報を取得する対象リスナーの名前を指すANSI文字列ポインター。
SecurityInformation	OBJECT_SECURITY_INFORMATION	in	取得するセキュリティ情報の種類を示すフラグ。DACL/SACL/所有者などを指定する。
pSecurityDescriptor	PSECURITY_DESCRIPTOR	outoptional	取得したセキュリティ記述子を受け取るバッファーへのポインター。
nLength	DWORD	in	pSecurityDescriptor バッファーのサイズ(バイト単位)。
lpnLengthNeeded	DWORD*	out	実際に必要なバッファーサイズ(バイト単位)を受け取る変数へのポインター。
