{
  DWORD msgType       = 0;

  LONG  errorOccured  = 0;

  // get data from SOME/IP message
  if((msgType = SomeIpGetMessageType(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)
  {
    write("SOME/IP message with Message Type 0x%02x received",msgType);
  } // if
}
