Problem when using WSAConnectByName, alway return socket error #10109
I tried on a Fresh installed Vista and my working Vista, using the sample code from MSDN help.
here is the source:
SOCKET OpenAndConnect(LPSTR NodeName, LPSTR PortName)
{
SOCKET ConnSocket;
int ipv6only = 0;
int iResult;
BOOL bSuccess;
SOCKADDR_STORAGE LocalAddr = {0};
SOCKADDR_STORAGE RemoteAddr = {0};
DWORD dwLocalAddr = sizeof(LocalAddr);
DWORD dwRemoteAddr = sizeof(RemoteAddr);
ConnSocket = socket(AF_INET6, SOCK_STREAM, IPPROTO_TCP);
if (ConnSocket == INVALID_SOCKET){
return INVALID_SOCKET;
}
iResult = setsockopt(ConnSocket, IPPROTO_IPV6,
IPV6_V6ONLY, (char*)&ipv6only, sizeof(ipv6only) );
if (iResult == SOCKET_ERROR){
closesocket(ConnSocket);
return INVALID_SOCKET;
}
bSuccess = WSAConnectByName(ConnSocket, NodeName,
PortName, &dwLocalAddr,
(SOCKADDR*)&LocalAddr,
&dwRemoteAddr,
(SOCKADDR*)&RemoteAddr,
NULL,
NULL);
if (bSuccess){
return ConnSocket;
} else {
fprintf(stderr,"Error Opening socket, error %d: %s\n",
WSAGetLastError(), PrintError(WSAGetLastError()));
return INVALID_SOCKET;
}
}
