Hello,

This is my problem, the function listed under this text does'nt seems to 
work correctly.

void requestHTTP(char *port, char *adress, char *request)
{
	int  cddbPort,cddbSocket;
	char response[MAX_CHAR];
	
	struct sockaddr_in	addr;
	struct hostent		*hp;
	
	cddbPort = atoi(port);
	cddbSocket = socket(AF_INET,SOCK_STREAM,0);
	hp = gethostbyname((char *) adress);
	if ( hp == NULL ) {
		printf("ERREUR: Nom de serveur inconnu !!!\n");
		exit(EXIT_FAILURE);
	}
	addr.sin_family = AF_INET;
	addr.sin_port = htons(cddbPort);
	memcpy(&(addr.sin_addr),hp->h_addr,sizeof(hp->h_addr));

	/* Connection au serveur décrit dans addr via la socket.*/
	printf("Connecting to server ...\n");
	if ( connect(cddbSocket,((struct sockaddr * )&addr),sizeof(addr)) == -1 
) {
		printf("ERROR: Unable to connect to server\n");
		exit(EXIT_FAILURE);
	}
	
	printf("Sending request : %s\n",request);
	send(cddbSocket,&request,sizeof(request),0);
	printf("Reading response ...\n");
	read(cddbSocket,&response,sizeof(response));
	printf("Response : %s",response);
	shutdown(cddbSocket,SHUT_RDWR);
	close(cddbSocket);
}

When I call the function requestHTTP("80","192.168.0.1","GET\n"), the 
function works fine until the read command (on the screen, there are the 
message "Reading response ..." and nothing else appens.

If I try to connect to my HTTP server with telnet 192.168.0.1 80
, when I type GET and enter, the server give the awaited response.

So I think that there are a bug in my function but I don't see where.

Is it possible to have little help ?

Thanks
