[Resolvido] Erro usando multi tarefas.

Estou tentando desenvolver algumas aplicações usando multitarefas para aprender.

Achei muuuita coisa na net que não dá certo de jeito nenhum, até encontrar a forma abaixo:

#include <windows.h>

#include <iostream>

DWORD WINAPI ThreadFn(LPVOID vpParam);

int main(){

	using namespace std;
	//Create the thread and pass in ther function pointer
	unsigned int uiCounter = 0;
	DWORD qThreadID;
	HANDLE hThread = CreateThread(0,0,ThreadFn,&uiCounter,0,&qThreadID);

	//Loop until the user enters 'q'
	char cChar = ' ';
	while (cChar != 'q'){
 printf("isso = %d",uiCounter);
 cChar = (char)getchar();
	}

	//Close the HANDLE to the thread
	CloseHandle(hThread);
	return 0;
}

DWORD WINAPI ThreadFn(LPVOID vpParam){

	unsigned int& uirCounter = *((unsigned int*)vpParam);
	//Increment up to the maximum value
	while (uirCounter < 0xFFFFFFFF){
 ++uirCounter;
	}
	return 0;
}

Porém está dando um erro que não consegui identificar o motivo. Alguém pode me ajudar?
