NAME
       XQueryTree - query window tree information

SYNTAX
       Status XQueryTree(display, w, rootreturn, parentreturn,
       childrenreturn, nchildrenreturn)
             Display *display;
             Window w;
             Window *rootreturn;
             Window *parentreturn;
             Window **childrenreturn;
             unsigned int *nchildrenreturn;

ARGUMENTS
       childrenreturn
                 Returns the list of children.

       display   Specifies the connection to the X server.

       nchildrenreturn
                 Returns the number of children.

       parentreturn
                 Returns the parent window.

       rootreturn
                 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 win-
       dow.  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.
