+ *
+ *  Description: returns information about the specified window
+ *  -----------
+ *
+ *  Inputs:
+ *  ------
+ *  window = window for which we are getting properties
+ * 
+ *  Outputs:
+ *  -------
+ *  argv = data returned from WM_COMMAND property (to restart client)
+ *  argc = number of arguments returned from WM_COMMAND property
+ *  clientMachine = which machine is client running on
+ *  xsmpClient = True if the client is XSMP and False otherwise
+ *  screen = window's screen number
+ *
+ *  Comments:
+ *  --------
+ *  All X (except GetWMHints) were not available until R4 and therefore have
+ *  R4 or greater dependencies.
+ *
+ *  BEWARE OF THESE ROUTINES:  The XGetWindowProperty routine returns 0 if
+ *  it succeeds.  These routines (which were derived from XGetWindowProperty
+ *  return 0 if they FAIL.
