C++类中创建线程

​ 经常会遇到需要在类中创建线程，可以使用静态成员函数，并且将类实例的指针传入线程函数的方式来实现。

实现代码代码如下：

/* 类头文件 CTestThread.h */
#include<iostream>
#include<process.h>
#include<Windows.h>

class TestThread
{
public:
	TestThread();
	~TestThread();

	 int StartThread();  // 开线程
	 int SetStopFlag(bool flag); //停止线程

private:
	static unsigned int WINAPI ThreadFunc(LPVOID lpParam);  //线程函数

private:
	bool m_bStopFlag;
};

/* 类源文件 CTestThread.cpp */

#include "CTestThread.h"

TestThread::TestThread()
{
	m_bStopFlag = false;
}

TestThread::~TestThread()
{
	m_bStopFlag = true;

}

int TestThread::StartThread()
{
	HANDLE hThread = (HANDLE)_beginthreadex(NULL, 0, &ThreadFunc, (LPVOID)this, 0, NULL);

	return 0;
}

int TestThread::SetStopFlag(bool flag)
{
	m_bStopFlag = flag;
	return 0;
}

unsigned int WINAPI TestThread::ThreadFunc(LPVOID lpParam)
{
	TestThread* pthis = (TestThread*)lpParam;
	while (!pthis->m_bStopFlag)
	{
		printf("ThreadFunc is running cassid is %d .\n",pthis->m_classid);
		Sleep(1000);
	}
	printf("ThreadFunc return.\n");
	return 0;
}

/* 测试代码 test.cpp */

#include "CTestThread.h"

int main()
{
	TestThread testThread(1);
	testThread.StartThread();

	char ch;
	while (ch = getchar())
	{
		if (ch == 'q' || ch == 'Q')
		{
			testThread.SetStopFlag(true);
			break;
		}
		Sleep(1000);
	}
}
