need help with sockets in C++

[cool_zephyr]

hey there..i'm a beginner in C++ and i'm written the following code using vc++ compiler..actually i took a little help from a book

#include<iostream>
#include<stdio.h>
#include<stdlib.h>
#include<winsock.h>

#define NETWORK_ERROR -1
#define NETWORK_OK 0

using namespace std;

int main(void)
{
	WSADATA ws;
	int nret;

	WSAStartup(MAKEWORD(1,1),&ws);

	SOCKET commsocket;

	commsocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
	
	if(commsocket==SOCKET_ERROR)
	{
		cout<<"Could not create communication socket"<<endl;
		WSACleanup();
		return NETWORK_ERROR;
	}

	
	//fill a SOCKADDR_IN structure with the information of the server
	SOCKADDR_IN serverInfo;
	serverInfo.sin_family=AF_INET;
	serverInfo.sin_addr.s_addr = inet_addr("209.191.93.53");
	serverInfo.sin_port=htons(80);

	nret=connect(commsocket,(struct sockaddr *) &serverInfo,sizeof(serverInfo));

	if(nret==SOCKET_ERROR)
	{
		cout<<"Could not connect to the server"<<endl;
		WSACleanup();
		return NETWORK_ERROR;
	}

	char sendbuffer[256]="GET / \r\n";
	char recvbuffer[256];
	char str[10000]="";

	nret=send(commsocket,sendbuffer,sizeof(sendbuffer),0);

	if(nret==SOCKET_ERROR)
	{
		cout<<"Could not send GET request"<<endl;
		WSACleanup();
		return NETWORK_ERROR;
	}

	do
	{
		strset(recvbuffer,' ');
		nret=recv(commsocket,recvbuffer,sizeof(recvbuffer),0);
		
		strcat(str,recvbuffer);
	}while(nret!=0);

	cout<<str<<endl;

	closesocket(commsocket);
	WSACleanup();

	return NETWORK_OK;
}

the above code runs alright but when i do the following..

SOCKADDR_IN serverInfo;
HOSTENT *h;
serverInfo.sin_family=AF_INET;
h=gethostbyname("www.yahoo.com");
serverInfo.sin_addr.s_addr= *((unsigned long *)h->h_addr);
serverInfo.sin_port=htons(80);

..this generates an error..could anyone please help me understand where i am going wrong??
