XQueryTree(3X11)                     BSD                      XQueryTree(3X11)



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 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.

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