NAME
       XQueryTree - query window tree information

SYNOPSIS
       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
       Returns	the  list  of  children.   Specifies  the connection to the X server.  Returns the number of children.	Returns the parent window.
       Returns the root window.  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 (NULL when there are no  chil-
       dren), and the number of children in the list for the specified window. 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.
