  SYNTAX
       Status XQueryTree(display, w, root_return, parent_return,

             Window *parent_return;
             Window **children_return;
             unsigned int *nchildren_return;

  ARGUMENTS
       children_return
                 Returns a pointer to 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.
