类成员作为线程入口函数

把类成员函数声明为友元函数。函数实现在类外实现。一定要这样。不然用其他奇葩少见的方法获取类成员函数的地址，会造成不可预料的后果。

线程入口函数的上下文参数传入this指针，以便访问类的proteted和private成员。

以下是示例代码:

//ThreadMember.cpp : 定义控制台应用程序的入口点。

#include"stdafx.h"

#include<string>

#include<Windows.h>

#include<iostream>

using namespace std;

class student

{

public:

    student()

    {

         m_handle = NULL;

         name = "Member fun  is ThreadFun.";

         age = 13;

    }

    friend UINT WINAPIprintInfo(LPVOID pvParam);

    void startUp();

 

private:

    HANDLE m_handle;

    int age;

    string name;

};

 

UINT  WINAPI printInfo (LPVOID pvParam)

{

    student * pS = (student * ) pvParam;

    while(true ){

        cout <<"age"<<pS-> age<<endl ;

        cout <<"name"<<pS->name <<endl;

        Sleep (2000);

    }

    return 0 ;

}

 

void student::startUp()

{

    m_handle =CreateThread(NULL,0,LPTHREAD_START_ROUTINE(printInfo),this,0,0);

}

 

int _tmain(int argc, _TCHAR*argv[])

{

   student s1;

    s1.startUp();

    system("pause");

    _CrtDumpMemoryLeaks();

    return 0;

}
