Strange Winsock2 Errors

[Yegg]

I've trying to get used to using Winsock2.h, however when I try my code out I receive strange errors. Here is the code, below it are the error messages.

#include <winsock2.h>
#include <stdio.h>

int main() {
SOCKET MainSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if(MainSocket == INVALID_SOCKET) {
printf ("Error connecting socket!\n");
return 0;
}
sockaddr_in clientService;
clientService.sin_family = AF_INET;
clientService.sin_addr.s_addr = inet_addr("asia.battle.net");
clientService.sin_port = htons(6112);
if(connect(MainSocket, (SOCKADDR*) &clientService, sizeof(clientService)) == SOCKET_ERROR) {
printf("Failed to connect!\n");
WSACleanup();
return 0;
}
printf("Connected to server.\n");
WSACleanup();
char buf[] = "\x03\x04CleanSlateBot\npasswordhere\n";
send(MainSocket, buf, sizeof(buf), 0);

return 0;
}

Any help is appreciated.

You need to include the winsock library in your project.

The following doesn't work and will always return bad:

inet_addr("asia.battle.net");


See msdn, it says "The inet_addr function converts a string containing an (Ipv4) Internet Protocol dotted address into a proper address for the IN_ADDR structure."

To resolve an internet URL, you want gethostbyname.

You may also need to do the following two things before you can use your socket.

WSADATA SocketData;
WSAStartup(MAKEWORD( 2, 2 ), &SocketData);

Thanks guys but I've already got the problems solved. I added ws2_32.lib to my project and I realized that inet_addr() will only accept the actual server ip. I thought I deleted my post but I guess Im not allowed to.

No need, perhaps someone can learn from this.

Good luck.
