[ENet-discuss] ENet-discuss Digest, Vol 61, Issue 1

[Lee Salzman]

Note, you don't set the client's address to ENET_HOST_BROADCAST (pass in 
NULL for the client's address structure to enet_host_create as usual). 
You attempt to connect to ENET_HOST_BROADCAST, which will send out the 
connection request to the broadcast address, which will just broadcast 
anywhere on the LAN. If there's something on the other end of the LAN 
waiting to accept, it will get a connection from it. If there are 
multiple servers on the other end that pick up the broadcasted connect 
request, then whichever replies back first wins. There should be nothing 
different about it otherwise.

You don't have to do anything special for LAN vs. internet for server 
addresses. Same stuff I described in previous email about IP applies.
