  if((msgId = SomeIpGetMessageId(messageHandle)) == 0)
  {
    // check if last function was executed correct
    if((errorCode = SomeIpGetLastError()) != 0)
    {
      write("SOME/IP IL error occured: Error code: %d", errorCode);
      errorOccured = 1;
    } // if
  } // if

  if(errorOccured == 0)
