what are the userinfo variables for notifications

[BigJohnny]

stuff like $vbulletin->userinfo['pmunread'] but one for each of the "notifications"

How do i find out what the userinfo vars are for all of these

unread profile visitor messages
profile visitor messages waiting approval
incoming friend requests
requests to join your social groups
invitations ot join social groups
unread picture comments
picture comments waiting approval
group messages waiting approval

basically i want the userinfo variables so i can set another variable based on eather or not those userinfo vars have something or not like if($vbulletin->userinfo['pmunread']!= 0)
