[C++ Win32] WSAStartup (winsock)

[gianvituzzi]

Salve,

sto cercando di eseguire il seguente codice:

#ifndef WIN32_LEAN_AND_MEAN
#define WIN32_LEAN_AND_MEAN
#endif

#include <windows.h>
#include <winsock2.h>
#include <ws2tcpip.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{

	WSADATA wsaData ={0};
	int iResult     = 0;

	// Initialize Winsock
	iResult = WSAStartup(MAKEWORD(2,2), &wsaData);



	printf("Hello World!\n");
	system("pause");
	return EXIT_SUCCESS;
}

ma ottengo questo errore:

unresolved external symbol __imp__WSAStartup@8 referenced in function _main

come includo questi simboli? (VC++ EE)

grazie
