#include <WinSock2.h>
#include <ws2tcpip.h>

}

if (0 != getaddrinfo(NULL, "6677", &hints, &res))

return -1;
}

SOCKET sk = socket(res->ai_family, res->ai_socktype, res->ai_protocol);

bind(sk, res->ai_addr, res->ai_addrlen);

if (0 != listen(sk, 5))
{
  WSACleanup();
  closesocket(sk);
  return -1;
}

struct sockaddr_storage storage;
int len = sizeof(storage);
memset(&storage, 0, len);

SOCKET newSk = accept(sk, (struct sockaddr*)&storage, &len);
