[ENet-discuss] Problem partailly solved

[Alexaroth]

Indeed it does not send any data... Now I have another issue:



How can I make a function like 

char* updateHost()
{string* b;
while (enet_host_service (server, & event, 100) > 0)
    {   switch (event.type)
        {         case ENET_EVENT_TYPE_RECEIVE:
          
              b=reinterpret_cast<char*>(event.packet->data);

             enet_packet_destroy (event.packet);
             return b;
             break;
}}}
I need to call from the main program the function like this:
if (updateHost()=="connected")
{cout>> Client connected !}

I practically want to return whatever packet a client/server sends me...

No packet is being sent indeed.
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).
