How to get the ID of a window according to some particular condition?


I know that in X window programming, if I know the ID of a particular window, I can manage it. For example, I can resize that window by using
XResizeWindow(display, win, 200, 300);

So my question is, how to get the window ID?

Particularly, when I know the PID of a program, how can I get the X window ID of the window in which it is running?

thanks in adv!

You haven't told us your distro.
You haven't told us your window manger.

Some wm's (fvwm comes to my mind) might integrate a way to implement this. However I don't think that the OP was asking about that, since he seems to be talking about xlib programming.

I am not into xlib programming, however I saw this sometime ago and bookmarked it for some reason:

It might or might not be useful, take a look just in case
