Hi
I’m trying to write a realy simple network game but it doesn’t work.
I read the chatd.c and I can’t see why my code doesn’t work…
IPaddress addr = {INADDR_NONE, GAMPORT};
if (argc > 1)
{
/* client */
SDLNet_ResolveHost(&addr, argv[1], GAMPORT); // port =
3942
sock = SDLNet_TCP_Open(&addr);
if (!sock)
{
printf("%s\n", SDL_GetError());
cleanup();
return -1;
}
SDLNet_TCP_AddSocket(sset, sock);
if (SDLNet_TCP_Send(sock, &argc, sizeof(int)) !=
sizeof(int))
printf(“Cannot send anything to server\n”);
}
else
{
/* server */
TCPsocket server = NULL;
server = SDLNet_TCP_Open(&addr);
if (!server)
{
fprintf(stderr, “Cannot create server : %s\n”,
SDL_GetError());
cleanup();
return -1;
}
SDLNet_TCP_AddSocket(sset, server);
hop:
if (!SDLNet_CheckSockets(sset, ~0))
printf(“error\n”);
printf(".");
if (!SDLNet_SocketReady(server))
goto hop;
sock = SDLNet_TCP_Accept(server);
if (!sock)
{
printf("%s\n", SDL_GetError());
cleanup();
return -1;
}
SDLNet_TCP_DelSocket(sset, server);
SDLNet_TCP_Close(server);
SDLNet_TCP_AddSocket(sset, sock);
}
there is another thing quite funny : if I make the client loop on the
TCP_Open, it connect to the server after hundreds attempts and the send
doesn’t return a bad value, but the server still doesn’t notice that
there is a client and wait at the CheckSocket…
Does anyone has a hint please?
Thanx, bye!

shouldn’t this be htons(GAMPORT)? --^
and why initialize it here since you reinicialize it for the client? why don’t initialize it only at the server block…?
that’s what I found… the rest I can’t check very much 'cose I don’t know about SDL_net… didn’t work with that yet…
Without the htons you’re binding the wrong port at the server, so the client would never reaches it…

was it helpful?

Hi!
IPaddress addr = {INADDR_NONE, GAMPORT};
shouldn't this be htons(GAMPORT)? --^
I’m not sure but I tried and it changed nothing… Actualy, as the
client and the server are initialized with the same value, even if the
port is not the one I expected, it should work…
and why initialize it here since you reinicialize it for the client? why don’t
initialize it only at the server block…?
I changed it.
was it helpful?
Unfortunatly not!
But thanx for trying to help! :o)
Too bad there is still no doc…
Anyone else has an idea?
Thanx, bye!

Where GAMPORT is defined and how?
they are not declared with the same value, since on the client you have to resolv the hostname with the portnumber as parameter… so it will automaticaly htons() the port number for you…
Too bad there is still no doc…
Yes… that’s why I didn’t work with it yet…
