Fstream logging
I am trying to figure out how to log data to a plain text file with this code:
ofstream myfile;
logfile.open ("test.txt");
logfile << "Message from " << inet_ntoa(remote_address.sin_addr) << ": " << message << endl;
logfile.close();Except the log is overwritten each time this executes. I know it's something simple, but i can't find it. I'm going to continue to look now..

I think it's something like std::ios::app or something...
Sorry, I haven't done a lot of file input/output.

Try:
ofstream myfile;
logfile.open ("test.txt", ofstream::app);
logfile << "Message from " << inet_ntoa(remote_address.sin_addr) << ": " << message << endl;
logfile.close();ofstream::app stands for append. |

logfile.open ("test.txt", ofstream::app);
logfile << "Message from " << inet_ntoa(remote_address.sin_addr) << ": " << message << endl;
logfile.close();hehe, ya.. i was having an error with that, looks like it wasn't only me who made the mistake though  . Thanks
