+ *  int _DtGetEmbeddedClients (display, root, ppEmbeddedClients, 
+ *					pNumEmbeddedClients)
+ *
+ *
+ *  Description:
+ *  -----------
+ *  Get the contents of the _DT_WORKSPACE_EMBEDDED_CLIENTS property 
+ *  from a root window. This is a array of top-level windows that are
+ *  embedded in the front panel of the window manager. They would
+ *  not be picked up ordinarily by a session manager in a normal
+ *  search for top-level windows because they are reparented to 
+ *  the front panel which itself is a top-level window.
+ *
+ *
+ *  Inputs:
+ *  ------
+ *  display		- display 
+ *  root		- root window to get info from
+ *  ppEmbeddedClients	- pointer to a pointer (to be returned)
+ *  pNumEmbeddedClients	- pointer to a number (to be returned)
+ *
+ *  Outputs:
+ *  -------
+ *  *ppEmbeddedClients	- pointer to a array of window IDs (top-level
+ *			  windows for embedded clients)
+ *                 	  (NOTE: This should be freed using XFree)
+ *  *pNumEmbeddedClients- number of window IDs in array
+ *  Return		- Success if property fetched ok.
+ *		  	  Failure returns are from XGetWindowProperty
+ * 
+ *  Comments:
+ *  --------
+ *  Use XFree to free the returned data.
