recv() Funktion

Der_Knob

Hi,

ich hab ein Problem mit recv()...

Und zwar bekomm ich nix zurück. Vielleicht sieht jemand von euch den Fehler:

Beim Fenster erstellen:

WSAStartup(MAKEWORD(2,0),&wsa);
s = socket(PF_INET,SOCK_STREAM,0);

//*** fill srv ***//
//empty srv
memset(&srv, 0, sizeof(srv));
//check if ipaddress is a address or dns string
if (inet_addr(IPAddress) == INADDR_NONE)
{
	dnsip = gethostbyname(IPAddress);
	if (dnsip)
		memcpy(&srv.sin_addr, dnsip->h_addr_list[0], sizeof(dnsip));
	else
		return 0;
}
else
{
	srv.sin_addr.s_addr = inet_addr(IPAddress);
}
srv.sin_port = htons(iPort);
srv.sin_family = AF_INET;

closesocket(s);
WSACleanup();

Beim connect:

int	iError_connect;
int	iError_send;
int	recvbytes = 1;
int	iError_recive = 0;
char recvbuf[64];

//*** create socket ***//
WSAStartup(MAKEWORD(2,0),&wsa);
s = socket(PF_INET,SOCK_STREAM,0);

//*** set timeout 1 sec ***//
int lenght = 1;
setsockopt(s,SOL_SOCKET,SO_RCVTIMEO,(const char*)&lenght,sizeof(lenght));

//*** connect to server ***//
iError_connect = connect(s,(struct sockaddr*) &srv, sizeof(srv));

//*** send request ***//
iError_send = send (s, cRequest, strlen(cRequest), 0);

//*** get recive ***//
do
{ 
	recvbytes = recv(s, recvbuf, sizeof(recvbuf), 0);
	if (recvbytes > 0)
		iError_recive++;
} while(recvbytes > 0);

closesocket(s);
WSACleanup();

iPort ist 8080
IPAddress ist 10.101.1.223
cRequest ist GET http://10.101.1.223/index.html HTTP/1.0\nHost: 10.101.1.223\n\n

oh man... ok hab den Fehler

bei:

if (inet_addr(IPAddress) == INADDR_NONE) 
{ 
    dnsip = gethostbyname(IPAddress); 
    if (dnsip) 
        memcpy(&srv.sin_addr, dnsip->h_addr_list[0], sizeof(dnsip)); 
    else 
        return 0; 
} 
else 
{ 
    srv.sin_addr.s_addr = inet_addr(IPAddress); 
}

da war das mit der Namensauflösung falsch!
Nicht:
memcpy(&srv.sin_addr, dnsip->h_addr_list[0], sizeof(dnsip));
sondern:
memcpy( (char *)&srv.sin_addr, dnsip->h_addr, dnsip->h_length);

Jetzt funkt das auch!!!
