XQueryTree(3X11)                                 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 XWIN 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 win-
     dow 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 bot-
     tommost (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.
