Re: TCPStream output flush() clears input

[Ian Campbell]

Thanks David,
    At the moment I was calling the flush() method of TCPStream. A bit like
this:

TCPStream *connection;
unsigned char *message;


// Fill message contents
message = new unsigned char[19];
....

// Create connection
connection = new TCPStream(remote_peer,remote_port,512,true);

// Some data appears on input from the TCP connection

// Write message out and flush to peer
for (int i = 0; i < 19; i++) {
    connection->put(message[i]);
}
connection->flush();

// Input data no longer available.

When I try it flush() seems to act exactly like sync() - but as far as I can
see you inherit it directly from std::iostream, but I would be curious to
know your thoughts.

How are you trying to "flush"?  Are you using sync or the flush or endl
stream manipulator?  I think sync() clears both currently.
