Quick question - style cookies

[antialiasis]

Okay, I'm pretty much finished with this style mod I'm making that makes vBulletin use the cookies from my main website for the skin selector. Now I've run into an unfortunate problem: I absolutely can't find where vBulletin sets the cookies when the style has been changed with the quick style switcher (or manual addition of ?styleid=whatever to the URL). Exactly which file has that code and where? Any help would be greatly appreciated.

It's in /includes/init.php

PHP Code:

// Set up user's chosen style
if ($vbulletin->GPC['styleid'])
{
    $styleid =& $vbulletin->GPC['styleid'];
    vbsetcookie('styleid', $styleid);
}
else if ($vbulletin->GPC[COOKIE_PREFIX . 'styleid'])
{
    $styleid = $vbulletin->GPC[COOKIE_PREFIX . 'styleid'];
}
else
{
    $styleid = 0;
}

It's working perfectly now. Thanks a lot!
