How to listup whole linked packages in specific project?

Hello.

I’m using version 2.6.
I have “TestProject” with more than 500 packages in it.
The api guide told me to use for specific package;

http://serverip:81/source/TestProject/samplepackage

In the response, I can figure it out whether it is linked one or not by checking <linkinfo> column or by checking existance of _link file.

Question is;
Is there any way to listup whole linked packages at once instead of visiting all packages like above?

I found the solution.
thanks.
