[ENet-discuss] Multicast/Broadcast Addresses

[Giuseppe Greco]

Hallo guys,

I'm wondering what's about multicast and broadcast addresses...

In the following statements it looks like broadcast datagrams
are not discarded:

static int
enet_protocol_handle_incoming_commands (
     ENetHost * host, ENetEvent * event)
{
         ...
         if (peer -> state == ENET_PEER_STATE_DISCONNECTED ||
             peer -> state == ENET_PEER_STATE_ZOMBIE ||
             (host -> receivedAddress.host != peer -> address.host &&
               peer -> address.host != ENET_HOST_BROADCAST))
           return 0;
         ...
}

Would it make sense to modify the statements above like this?

static int
enet_protocol_handle_incoming_commands (
     ENetHost * host, ENetEvent * event)
{
         ...
         if (peer -> state == ENET_PEER_STATE_DISCONNECTED ||
             peer -> state == ENET_PEER_STATE_ZOMBIE ||
             (host -> receivedAddress.host != peer -> address.host &&
               peer -> address.host != ENET_HOST_BROADCAST) &&
               !IN_IS_ADDR_MULTICAST (peer -> address.host) ))
           return 0;
         ...
}

Of course, ENetHost/ENetSocket would need to be modified in order to
let applications join the desired multicast groups...

I'm just trying to understand whether or not ENet would be
suitable for multicasting.
