Invalid AWS- / How to be sure if image is removed from the edge

Question

I want to invalidate the root directory and http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Invalidation.html#invalidation-specifying-objects

It says we can use wild cards

Say we have a way like

https: //cdn_url/rootimage/first/1/type/1.png

https: //cdn_url/rootimage/first/1/type/2.png

https: //cdn_url/rootimage/first/2/type/1.png

https: //cdn_url/rootimage/first/2/type/2.png

https: //cdn_url/rootimage/second/1/type/1.png

https: //cdn_url/rootimage/second/1/type/2.png

https: //cdn_url/rootimage/second/2/type/1.png

https: //cdn_url/rootimage/second/1/type/2.png

So if I write

 AmazonCloudFrontClient objClient = new AmazonCloudFrontClient(ConfigurationManager.AppSettings["s3accesskey"], ConfigurationManager.AppSettings["s3secret"]);
        objClient.CreateInvalidation(new CreateInvalidationRequest
        {
            DistributionId = ConfigurationManager.AppSettings["CDNDistributionId"],
            InvalidationBatch = new InvalidationBatch 
            { 
                Paths = new Paths { Items = "/cdn_url/rootimage/*", Quantity = 1 } 
            }
        });

Will the above code work. and how about the quantity will be 1 or the quantity of all the actual images.
