As using compiz as a wm, could I get the pointer position on the screen?

I used dbus-inspector to looked into org.freedesktop.compiz, nothing useful.
Should I use C API?
Thanks.

In master (but not in 0.6), there is a mousepoll plugin which can be used to poll the mouse cursor position for another plugin. The mag and showmouse plugins both use mousepoll for this purpose.

If you push a screengrab, you can get MotionNotify event. Have a look at how freewins does it. Resort to mouse polling later as it is costly on the CPU

Thank you all.
I am looking mousepoll's source. While SmSpillaz metioned CPU costs, I would think about it.
I want to make a application (or plugin?) that draw a fancy clock beside (I mean following) mouse pointer. So I need to know every time mouse moved.
Maybe paintCursorProc would help?

You may want to look at show-mouse plugin (which uses mousepoll to find the mouse location)

[Magicloud]

As its name, mousepoll uses a polling mechanism. I do not know if it is better than an "event driven" paintCursorProc.
I have written some code, whic makes my compiz hung. Could someone help me?
pointerclock.c (http://magiclouds.googlepages.com/pointerclock.c.html)
Thanks.

I noticed that you don't use any of the standard structs and macros (which may or may not be related to the problem). Probably the best place to find help would be on IRC - #compiz-fusion-dev on Freenode

[SmSpillaz]

If you aren't pushing screen-grabs (locking the input to compiz) then use mousepoll.
