$userinfo in plugin?

[zivester]

What is the equivalent of $userinfo outside of the templating system? $vbulletin->userinfo is actually $bbuserinfo from what I can tell.

I'm trying to get $userinfo->[field8] in one of my plugins, but all I can access is the actual logged in user (usually $bbuserinfo) as $vbulletin->userinfo.

I wish there was a general howto for something like this.
