To get the complete list of active clients inside Xorg

Question

Could someone please point me to a place(PDF) where I can find the detail description about the Xserver(Xorg) e.g DIX Layer, OS Layer etc.

Specifically I am looking for how to get the complete list of all the active clients from inside the Xserver(Xorg). How does Xorg maintain this list? Whenever a new request arrives to Xorg, after accepting the connection where does it put information about that client?

Thanks

Why do you ask? What do you want to achieve? You might use the xlsclients command. – Nam

Answer 1

Run xlsclients.

http://cgit.freedesktop.org/xorg/app/xlsclients

Documentation about Xorg internals:

• http://cgit.freedesktop.org/xorg/xserver/tree/doc
• http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/doc
• http://cgit.freedesktop.org/ -> many apps and libraries contain their own documentation

Still, reading the source code is usually the best way, since the documentation about Xserver internals is not updated regularly.

The xlsclients is simply llisting some properties (pieces of random data attached to windows) set on the top windows. It's completely worthless and unreliable. – Danseur
