Jerry:
	Here are the code segments:

/* check the window state, call it when you get a PropertyNotify event */
void checkState(w, cd, event)
Widget w;
char *cd;
XPropertyEvent *event;
{
  Arg args[1];
  Boolean iconic;
  Atom actual_type, atom;
  int  actual_format;
  unsigned long nitems, bytes_after;
  unsigned char *data;
  long     *state;

    atom = XInternAtom(display, "WM_STATE", False);

    XGetWindowProperty(display, window, atom,
		       0L, 1L, False, AnyPropertyType,  &actual_type,
		       &actual_format, &nitems, &bytes_after, &data);

    printf("actual_type: %s, actual_format: %d, nitems: %d, bytes_after: %d\n",
	   XGetAtomName(dpy, actual_type), actual_format, nitems, bytes_after);

    state = (long *)data;
    if (*state == NormalState) printf("NormalState\n");
    if (*state == IconicState) printf("IconicState\n");
    if (*state == WithdrawnState) printf("WithdrawnState\n");

    free(date);
    return;
  }

}


/* to iconfoy a window */
   void IconifyShell(w, d1, d2)
        Widget w;
        caddr_t d1, d2;
   {
     XClientMessageEvent event;
     Window win;
     Display *dpy;

     event.type = ClientMessage;
     event.send_event = True;
     dpy = event.display = XtDisplay(w);
     win = event.window = XtWindow(ApplicationShellWidget);
     event.message_type = XInternAtom(dpy, "WM_STATE", False);
     event.format = 32;
     event.data.l[0] = IconicState;
     XSendEvent(dpy, DefaultRootWindow(dpy), False,
                SubstructureRedirectMask | SubstructureNotifyMask, &event);
     XFlush(dpy);
     sleep(3);
     XMapWindow(dpy,win);
   }


I think you can figure out how to deiconify. yes, change the above
event.data.l[0] = NormalState;
