Normally, you want to use this function to check in frontend if there is a backend session. To check this, you must call ```session_start()``` first.
In Rex4 you had to do it yourself, for example see https://github.com/redaxo/redaxo/commit/d84e734100a345d744f0a6e33f0d0c1cb2580cd2#L1R25 (I've forgotten to delete it there).
In my opinion this function makes no sense without ```session_start()```.
