IiopWWIsA( in hIiop       : number,
           in sIdentifier : string ): boolean;

Example

dcltrans
  transaction TWWRequest
  const
    WW_HOST := "192.168.20.35"; // Wonderwall host
    WW_PORT := 16000;           // Wonderwall port
    HOST    := "192.168.20.21"; // server
    PORT    := 1052;            // port
  var
    hDaemon, hBank : number;
    bRet           : boolean;
  begin
    IiopSetMaxGiopVersion("1.2");
    IiopSetByteOrder(IIOP_BIG_ENDIAN);
    IiopWWBind(WW_HOST, WW_PORT);

    // OrbixWeb bootstrapping with Wonderwall
    hDaemon := IiopWWDaemonBind(HOST, PORT);

   // get proxy object reference to bank object
    hBank := IiopWWServerBind(hDaemon, HOST, "bank", "", "bank");
    bRet := IiopWWIsA(hBank, "IDL:bank:1.0");
    ...
  end TWWRequest;
