The same thing happens to me if the client does nothing (no events to
send, ect) even when calling enet_host_service() on a regular basis. I
just added an unreliable "ping packet" every once in a while which
solved it.

Hey there.
On your while(true) on the client you must also call enet_host_service
in order for the client to keep its connection alive.

Hello!
I wrote the base client accordingly the tutorial and the client which
read inputting through console characters and send it to the server.
Everything is fine but just first 30 seconds - then happen the
disconnection (message "Client information disconnected" shown).
What is wrong with my code?
Server code:
#include <cstdio>
#include "enet\enet.h"
int main(int argc, int** argv)
{
if (enet_initialize () != 0)
{
printf ("An error occurred while initializing ENet.\n");
goto END;
}
ENetAddress address;
address.host = ENET_HOST_ANY;
address.port = 1234;
ENetHost* server = enet_host_create ( & address, 32, 2, 0, 0);
if (server == NULL)
{
printf("An error occurred while trying to create an ENet
client host.\n");
goto END;
}
ENetEvent event;
WAIT_FOR_AN_EVENT:
enet_host_service(server, &event, 5);
switch (event.type)
{
case ENET_EVENT_TYPE_CONNECT:
printf ("A new client connected from %x:%u.\n",
event.peer ->
address.host, event.peer -> address.port);
event.peer -> data = "Client information";
break;
case ENET_EVENT_TYPE_RECEIVE:
printf ("A packet of length %u was received from %s
on channel %u.
Containings:\n %s", event.packet -> dataLength, event.peer -> data,
event.channelID, event.packet -> data);
enet_packet_destroy (event.packet);
break;
case ENET_EVENT_TYPE_DISCONNECT:
printf ("%s disconected.\n", event.peer -> data);
event.peer -> data = NULL;
break;
case ENET_EVENT_TYPE_NONE:
break;
}
goto WAIT_FOR_AN_EVENT;
printf("host halted.\n");
END:
getchar();
return 0;
}
Client code:
#include <cstdio>
#include "enet\enet.h"
#include <vector>
int main(int argc, int** argv)
{
//where reading console data will be stored:
std::vector<char> buffer;
if (enet_initialize () != 0)
{
printf ("An error occurred while initializing ENet.\n");
goto END;
}
ENetHost* client = enet_host_create ( NULL, 1, 2,
57600 / 8, 14400 / 8);
if(client == 0l)
{
printf("An error occurred while trying to create an
ENet server host.\n");
goto END;
}
ENetAddress address;
enet_address_set_host(&address, "localhost");
address.port = 1234;
ENetPeer* peer = enet_host_connect(client, &address, 2, 0);
if(peer == 0l)
{
printf("No available peers for initiating an ENet
connection.\n");
goto END;
}
ENetEvent event;
if (enet_host_service (client, & event, 5000) > 0 &&
event.type ==
ENET_EVENT_TYPE_CONNECT)
{
puts ("Connection to localhost:1234 succeeded.");
}
else
{
enet_peer_reset (peer);
puts ("Connection to localhost:1234 failed.");
goto END;
}
printf("Input some data which will be sent to server...\n");
INPUT_DATA:
buffer.clear();
while(true)
{
char character = getchar();
buffer.push_back(character);
if(character == '\n')
{
break;
}
}
buffer.push_back('\0');
ENetPacket * packet = enet_packet_create(&buffer[0],
buffer.size(),
ENET_PACKET_FLAG_RELIABLE);
enet_peer_send (peer, 0, packet);
enet_host_flush(client);
goto INPUT_DATA;
END:
getchar();
return 0;
}
