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);
  }
}
