NAME
      XQueryTree - query window tree information

SYNTAX
      Status XQueryTree(display, w, root_return, parent_return,
      children_return, nchildren_return)
            Display *display;
            Window w;
            Window *root_return;
            Window *parent_return;
            Window **children_return;
            unsigned int *nchildren_return;

ARGUMENTS
      children_return
                Returns the list of children.

      display   Specifies the connection to the X server.

      nchildren_return
                Returns the number of children.

      parent_return
                Returns the parent window.

      root_return
                Returns the root window.

      w         Specifies the window whose list of children, root, parent, and
                number of children you want to obtain.

DESCRIPTION
      The XQueryTree function returns the root ID, the parent window ID, a
      pointer to the list of children windows, and the number of children in
      the list for the specified window.  The children are listed in current
      stacking order, from bottommost (first) to topmost (last).  XQueryTree
      returns zero if it fails and nonzero if it succeeds.  To free this list
      when it is no longer needed, use XFree.

BUGS
      This really should return a screen *, not a root window ID.
