How to display all of CI sessions?

[eluser]shinokada[/eluser]
I can display php session with print_r ($_SESSION); to check my php session.

I want to check CI session.

Is there any equivalent to print_r ($_SESSION); to display all the CI session?

Or do I have to specify?

Thanks in advance.

print_r($this->session->userdata); would do that
