[C++]Sock

Ho cercato di farmi una lib socket per Lin-Win e questo il risultato:

 
/// The Os inclusion
 #ifdef WINDOWS
 	#include <Winsock2.h>
    #include <windows.h> 
 #elif
 	#include <sys/types.h>
	#include <sys/socket.h>
	#include <netinet/in.h>
	#include <netdb.h>
 #endif	  

#include <string>

class WinClientSock
{
 std::string addr;
 #ifdef WINDOWS
  SOCKET sock_fd; /// the win socket
 #elif
  int sock_fd; /// the lin socket
 #endif
 struct sockaddr_in temp; /// the sockaddr structure
 struct hostent *h; /// the host structure
 int port;
 public:
 WinClientSock();
 WinClientSock(const std::string addr, int port);
 ~WinClientSock();
 int Open();
 void Exit();
 const char *getHost()
 {
  return addr.c_str();
 };
 const int getPort()
 {
  return port;
 };
 int Receve(char *buf);
 int Send(char * buff);
};

WinClientSock::WinClientSock() 
{
 addr = "localhost";
 /// defining port
 #ifdef DEF_PORT
 	port = 6000;
 #elifdef DEF_PORT
 	port = DEF_PORT;
 #endif	  
}

WinClientSock::WinClientSock(const std::string addr, int port)
{
 this->port = port;
 this->addr = addr;
}

WinClientSock::~WinClientSock()
{ 	
		Exit();
}

int WinClientSock::Open()
{
   int ret;
   #ifdef WINDOWS
 	WSADATA wsaData;
	WORD version;
    int error;
	
    version = MAKEWORD( 2, 0 );
    error = WSAStartup( version, &wsaData );
	
	/* check for error */
	if ( error != 0 )
	{
	 return -1;
	}
	
	/* check for correct version */
	if ( LOBYTE( wsaData.wVersion ) != 2 || HIBYTE( wsaData.wVersion ) != 0 )
	{
     WSACleanup();
	 return -1;
	}
    
	sock_fd = socket( AF_INET, SOCK_STREAM, 0 );
	
	h = gethostbyname(addr.c_str());
	
	temp.sin_family = AF_INET;
	temp.sin_addr.s_addr = ((struct in_addr *)(h->h_addr))->s_addr;
	temp.sin_port = htons(port);
	
	if ( connect( sock_fd, (sockaddr*)&temp, sizeof(temp) ) == SOCKET_ERROR )
	{
     /* could not connect to server */
     ret = -1;
	}
	else
	{
	 ret = sock_fd;
	}

   #elif
  	temp.sin_family = AF_INET;
	temp.sin_port = htons(PORT);
	
	h = gethostbyname(addr.c_str());
	
	if (0 == h) return -1;
	
	bcopy(h->h_addr,&temp.sin_addr,h->h_length);
	
	sock_fd = socket(AF_INET,SOCK_STREAM,0);	
	
	errore = connect(sock_fd,(struct sockaddr*) &temp, sizeof(temp));

	if(errore == 0)
	{
	  ret = sock_fd;
	}
	else
	{
      ret = -1;
	}
   #endif
   return ret;
}

void WinClientSock::Exit()
{
 #ifdef WINDOWS
 	closesocket(sock_fd);
	WSACleanup();
 #elif
    close(sock_fd);
 #endif
}

int WinClientSock::Receve(char *buf)
{
    if(recv(sock_fd, buf, strlen(buf), 0 ) == 0)
	{
		return -1;
	}
}

int WinClientSock::Send(char *buf)
{
    if(send(sock_fd, buf, strlen(buf), 0 ) == 0)
	{
		return -1;
	}
}

Il problema è che provandola:

 
#include <iostream>
#include <cstring>
#include "WinSockClient.hpp"

using namespace std;

int main(int argc, char *argv[])
{
  WinClientSock sk("http://www.ngi.it", 23);
  SOCKET client =  (SOCKET) sk.Open();
  if(-1 != client)
  {
	  cout << "Open Ok \n";
     
	  char * buffer = new char[32];

	  /*
	  if(sk.Receve(buffer) == -1)
	  {
		cout << "Error in recv\n";
	  }
	  else
	  {
		cout << buffer;
	  }
      */
	  
	  if(sk.Send(buffer) == -1)
	  {
		cout << "Error in send\n";
	  }
	  else
	  {
		cout << "Ok\n";
	  }
	  
	  delete[] buffer;
  }
  char c;
  cin >> c;
  return 0;
}

Mi da errore di memoria che doveva essere read

Why???

ho semi risolto, ora pero mi da connection ok ma nientaltro su linux e niente di niente su win:
