Windows程式設計中執行緒同步的主要機制：互斥、事件、訊號量、可等待定時器，不說了，直接上程式碼：

// ThreadSync.cpp : 定義控制檯應用程式的入口點。
//

#include "stdafx.h"
#include <windows.h>

#define TEST_EVENT_NAME TEXT("TEST_EVENT")
#define TEST_MUTEX_NAME TEXT("TEST_MUTEX")
#define TEST_SEMAPHORE_NAME TEXT("TEST_SEMAPHORE")
#define TEST_WATIABLETIME_NAME TEXT("TEST_TIMER")
