NAME
       XQueryTree - query window tree information

SYNTAX
       Status XQueryTree(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

       root_return

       w	 Specifies the window whose list of children, root, parent,
		 and number of children.

DESCRIPTION
       The XQueryTree function returns the root ID, the parent window ID, a
       pointer to the list of children windows (NULL when there are no chil-
       dren), and the number of children in the list for the specified win-
       dow.  The children are listed in current stacking order, from bottom-
       most (first) to top-most (last).	 XQueryTree returns zero if it fails
       and nonzero if it succeeds.  To free a non-NULL children list when it
       is no longer needed, use XFree.

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