getaddrinfo win ce 6.0

[Destiniy]

Hallo Leute,

ich sende Broadcasts in Win XP (oder 7)

memset(&hints, 0, sizeof hints);
	hints.ai_family = AF_UNSPEC; // AF_INET or AF_INET6 to force version
	hints.ai_socktype = SOCK_DGRAM;
	hints.ai_protocol = IPPROTO_UDP;
	hints.
	if (!(cError = getaddrinfo((const char *)"255.255.255.255", (const char *)"5123", &hints, &res)))
	{
		if (INVALID_SOCKET != (hSocketSend = socket(res->ai_family, res->ai_socktype, res->ai_protocol)))
		{
			bOptVal = true;
			if (SOCKET_ERROR != setsockopt(hSocketSend, SOL_SOCKET, SO_BROADCAST, (char*)&bOptVal, sizeof(bOptVal))) 
			{					
				SentBytes = sendto(hSocketSend,(char *)pData,uwDataLength,0,res->ai_addr, (int)res->ai_addrlen);		
			}
			closesocket(hSocketSend);
		}
		freeaddrinfo(res);
	}

Dies klappt auch wunderbar. Wenn ich das jetzt in Win CE 6.0 probiere bringt mir getaddrinf den Fehler 11001 (Unknown Host).

Woran könnte dies liegen?

MfG
