C++ (Cpp) handlePack Examples

Example #1

File: Client.cpp Project: DavidZeni/vcmi

void CClient::run()
{
	setThreadName("CClient::run");
	try
	{
		while(!terminate)
		{
			CPack *pack = serv->retreivePack(); //get the package from the server
			
			if (terminate) 
			{
				vstd::clear_pointer(pack);
				break;
			}

			handlePack(pack);
		}
	} 
	//catch only asio exceptions
	catch (const boost::system::system_error& e)
	{	
        logNetwork->errorStream() << "Lost connection to server, ending listening thread!";
        logNetwork->errorStream() << e.what();
		if(!terminate) //rethrow (-> boom!) only if closing connection was unexpected
		{
            logNetwork->errorStream() << "Something wrong, lost connection while game is still ongoing...";
			throw;
		}
