How to check if user is authenticated?

[null]

I need to add some code to vB.

How do I check if user is authenticated? What variables do I use? Basically I'm asking for vb API.

Appreciate your help

We do not have access to the license system if that is what you are looking for, it is custom coding for vBulletin and Jelsofts' license system.

I mean what code should I write to check if user is authenticated?

Ok, figured out

PHP Code:

if(isset($_COOKIE["bbuserid"]))
  $authenticated = true;
else
  $authenticated = false;
