C++類中創建線程

​ 經常會遇到需要在類中創建線程，可以使用靜態成員函數，並且將類實例的指針傳入線程函數的方式來實現。

實現代碼代碼如下：

/* 類頭文件 CTestThread.h */
#include<iostream>
#include<process.h>
#include<Windows.h>

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

	 int StartThread();  // 開線程
	 int SetStopFlag(bool flag); //停止線程

private:
	static unsigned int WINAPI ThreadFunc(LPVOID lpParam);  //線程函數

private:
	bool m_bStopFlag;
};

/* 類源文件 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;
}

/* 測試代碼 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);
	}
}
