CreateThread

1.线程创建API

1. CreateThread，需要调用到CRT库时，不要用这个；
2.  BeginThread，RTL库里的System单元中定义；
3. 在MFC程序中，应该调用AfxBeginThread函数；
4. 在Visual C++程序中应调用_beginthreadex函数；需要调用到CRT库时。

demo

// DemoFunc.cpp : 定义控制台应用程序的入口点。
//
#include "stdafx.h"
#include <stdio.h>
#include <iostream>
#include <windows.h>
#include <strsafe.h>//win2003SDK必须安装　要不无此头文件。此文件是为了实现StringCchPrintf，StringCchLength。

函数

1. WaitForMultipleObjects
2. WaitForSingleObject

多线程同步方法：

• Console input buffers
• Events
• Mutexes
• Processes
• Semaphores
• Threads
• Timers
