How to find user's online_status knowing its userid and username

[catalin8]

what would be the best way to find if a user is online or not if I know its id and name.

I need this done outside vb directory
( I have /global.php included
cookies set to the main domain )

thank you

functions_bigthree.php

// ###################### Start getOnlineStatus #######################
// work out if bbuser can see online status of user
// also puts in + and * symbols as $user[buddymark] and $user[invisiblemark]
function fetch_online_status(&$user, $setstatusimage = false)


As the function expects a userinfo array, you have to get the required filds first.
