Entry Point Not Found?!

Hi, so I'm getting a pop up error message with a title of "Entry Point Not Found" and a message of "The procedure entry point InetNtopW could not be located in the dynamic link library WS2_32.dll". This happens when I run this program, the second I launch it the message pops up, it doesn't even print the first line. Without the inet_ntop function call it will compile/work correctly though. I also tried replacing inet_ntop with a call to inetNtop, and it just does the exact same error pop up. I'm using Unicode character set of that's important (which is default as far as I know).

I took a screenshot for you: http://img79.imageshack.us/my.php?im...goingonzc2.jpg

Here is the code:

Code:

#include <iostream>
#include <winsock2.h>
#include <ws2tcpip.h>
#include <cstring>

using std::cout;
using std::cin;
using std::endl;

WSADATA wsaData;

int main(int argc, char * argv[]) {
	int wsaReturnVal = WSAStartup(MAKEWORD(1, 1), &wsaData);
	if (wsaReturnVal) {
		cout << "Error number: " << wsaReturnVal << endl;
		exit(1);
	}
	char * fpoint = strrchr(argv[0], '\\');
	if (argc != 2) {
		printf("Usage: <&#37;s> <hostname>", fpoint+1);
		exit(1);
	}
	struct addrinfo hints, *res, *p = NULL;
	memset(&hints, 0, sizeof(hints));
	hints.ai_flags = AI_PASSIVE;
	hints.ai_family = AF_UNSPEC;
	hints.ai_socktype = SOCK_STREAM;

	int status = getaddrinfo(argv[1], NULL, &hints, &res);
	if (status == -1) {
		cout << "getaddrinfo error." << endl;
		exit(1);
	}
	
	printf("IP address for %s: ", argv[1]);
	for (p = res; p != 0; p = p->ai_next) {
		void * addr;
		char * ipVer;
		if (p->ai_family == AF_INET) {
			struct sockaddr_in * IPv4 = (struct sockaddr_in *)p->ai_addr;
			addr = &(IPv4->sin_addr);
			ipVer = "IPv4";
		}
		else {
			struct sockaddr_in6 * IPv6 = (struct sockaddr_in6 *)p->ai_addr;
			addr = &(IPv6->sin6_addr);
			ipVer = "IPv6";
		}
		char ipBuff[46];
		inet_ntop(hints.ai_family, addr, ipBuff, sizeof(ipBuff));
		printf("%s: %s", ipVer, ipBuff);
	}


	freeaddrinfo(res);

	if (WSACleanup()) {
		cout << "Cleanup Error." << endl;
		exit(1);
	}
}

Cheers.

It's Vista or Server 2008 only.

So... both inet_ntop and InetNtop are Vista or Server 2008?! Geeze... That's lame. Ahwell, cheers bud.
