    I'm working on a client which forks off some other clients.  I am
    trying to determine how the first program can iconify all of the
    others (ie Iconify Session).  As I understand it, the window state
    is private and cannot be modified by a program other than the
    window manager.  Can another program use the same mechanism??

The WM_STATE property is indeed private and shouldn't be modified by
programs other than the window manager.

However, programs can indeed request state changes of windows that they
didn't create.  All you need is the XID of the windows of the clients you
fork off.  Once you have these IDs, you can call XIconifyWindow() and
XMapWindow() to iconify and deiconify them.

Now, getting your hands on the XIDs of the other windows may be tricky.
If you wrote the child program, one approach is to have it write its
window id(s) into a pipe back up to the parent.
