I am having a problem connecting to the battle.net server. When i pass uswest.battle.net:6112 to my open function no connection is made but if i was to pass 63.241.83.8 then connection is successful.
int Connection::open(char *addr, short p)
{
struct sockaddr_in s;
struct hostent *hent;
if(wSock != -1)
closesocket(wSock);
if ((s.sin_addr.s_addr = inet_addr(addr)) == -1)
{
hent = gethostbyname(addr);
if (hent == NULL)
return -1;
s.sin_addr = *((struct in_addr *)hent->h_addr);
}
s.sin_port = htons(p);
s.sin_family = AF_INET;
wSock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if(connect(wSock, (struct sockaddr *)&s, sizeof(struct sockaddr)))
MessageBox( NULL, "CONNECTED","",MB_OK);
else
MessageBox(NULL, "FAILED TO CONNECT","",MB_OK);
Now when i pass uswest.battle.net to this function it exits on this line of code:
if (hent == NULL)
return -1;
Any ideas?
Are you calling WSAStartup anywhere? And try doing if inet_addr() == INADDR_NONE and not -1

Tried what you said:
int Connection::open(char *addr, short p)
{
WSADATA W;
WSAStartup(MAKEWORD(2,0), &W);
struct sockaddr_in s;
struct hostent *hent;
if(wSock != -1)
closesocket(wSock);
if ((s.sin_addr.s_addr = inet_addr(addr)) == INADDR_NONE )
{
hent = gethostbyname(addr);
if(hent == NULL) return -1;
s.sin_addr.s_addr = inet_addr(hent->h_addr);
}
s.sin_port = htons(p);
s.sin_family = AF_INET;
wSock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if(connect(wSock, (struct sockaddr *)&s, sizeof(struct sockaddr)))
MessageBox( NULL, "CONNECTED","",MB_OK);
else
MessageBox(NULL, "FAILED TO CONNECT","",MB_OK);
}Now after making these changes, the socket will connect when i use uswest.battle.net and not 63.241.83.8
Any ideas guys? this was a problem with my last socket as well.
I don't recall DNS lookup's supporting the hostname:port notation. Also, gethostbyname() is out of date, use getaddrinfo().

Connect returns 0 on success...
