   *That* is a much clearer question. Thanks!   
      
   I'm not sure, but one of the experts will probably answer.   
      
   I personally do not want to know, because I think using   
   MSG_PEEK is a sign of a bad design. There is usually a   
   better way of solving the problem (whatever the problem is).
