Check away status

Hi everyone, I tried to search for this, but "away" is too common of a word for the forum's search engine.

How do you check/listen for whether or not a sitting avatar is away? I'd like to make a script that will unsit an avatar if it ever takes an Away or Busy status, but I couldn't find an event that would read that information. Any help available for me?

Thanks in advance!

Look for llGetAgentInfo() in a wiki.

if (llGetAgentInfo(av_key) & AGENT_AWAY)
{
// Agent is away...
}
