安全描述符与未命名对象相关？

Question

创建未命名的对象时，例如使用带有lpName == nullptr的CreateEvent，是否在LPSECURITY_ATTRIBUTES中传递的安全描述符与任何内容相关？特别是，DACL或完整性级别是否用于限制任何情况下的访问？

Microsoft's Raymond Chen actually addressed this question in the Old New Thing blog, listing inheritance and DuplicateHandle as places where the security descriptor is relevant for unnamed objects: https://blogs.msdn.microsoft.com/oldnewthing/20150604-00/?p=45451
