<div id="yiv1504995966">No packet is being sent indeed.<br>The peer->data is a local pointer that only 'lives' at the computer that defines it. Nothing is send; you need packets for that. It's just to associate computer-local data with the peer (a peer is a computer, not a packet).<br>

There's no packet size for peer data (at least from what the docs tell me about the _ENetPeer struct), since he's probably not sending a packet. He's just setting the peer's data to the name, not a packet's data.<br>
