ofxTCPServer in a thread

advanced
#1

Hi,

I try to run the ofxTCPServer in a seperate thread like this:

class ViflowTcpServer : public ofThread
{
public:
	ViflowTcpServer()
	{
		ofxTCPSettings tsettings(12000);
		tsettings.blocking = true;
		server.setup(tsettings);
		server.setVerbose(true);
	};
	ofxTCPServer server;
	void threadedFunction();
};

The threadedFunction looks like this, taken from the example:

void ViflowTcpServer::threadedFunction()
{
	bool forever = true;
	while (forever)
	{
		for (unsigned int i = 0; i < (unsigned int)server.getLastID(); i++)
		{
			if (!server.isClientConnected(i))continue;
			string str;
			string tmp;
			do {
				str += tmp;
				tmp = server.receive(i);
			} while (tmp != "");
			if (str.length() > 0)
			{
				ofLog() << "Received: " << str << "\n";
			}
		}
		ofLog() << "Doing something...";
		sleep(1000);
	}
}

I expected that the ofxTCPServer is blocking until it receives something if I set “blocking” in the settings to true, but this is not the case. How can I setup the ofxTCPServer in a way it waits until a client connects?

Okay, it seems that if I add a

server.waitConnectedClient();

as first command in my loop it behaves as expected.
