RE: How to derive the process ID of its own session?

If you are interested in the OS foreground process then see the following article:

Is there a way to trace a unix process id to a SID and SERIAL# ? http://www.jlcomp.demon.co.uk/faq/sid_from_proc.html

The article is going the other way, from pid to sid, but the information you need is identified in the covered material.

Thank you for the answer, it is more surprising than I thought. But the spid I was looking for was the foreground OS process which I thought should not be shared right? Ie, different foreground process using the same background process in a shared server scenario - correct?
