I would like to see it nicely documented like in this other udp library: <a href="http://airhook.ofb.net/protocol.html">http://airhook.ofb.net/protocol.html</a><br><br>They show an image in a format that you would readily see to describe the udp/tcp packet headers...<br>

As someone already mentioned, ENET packs more than one user packet into<br>
a single UDP packet. But I'm not exactly sure how one should handle that.<br>
And the UDP header size is always 64 bits (8 bytes.)<br>
<br>
Also, I think you should take into account the IP protocol header as<br>
well. If you use IPv4, which you probably do, the header size is<br>
somewhere between 160 bits (20 bytes) and 480 bits (60 bytes.) But the<br>
excess header size is due to IPv4 "options" which, AFAIK, are seldom (if<br>
ever) used any more.<br>
If you happen to use IPv6 (does ENET even run on this?) the header size<br>
for that is a fixed 320 bits (or 40 bytes.)<br>
<br>
Hope this helps.<br>
