win32下線程封裝

首先建立一個MyThread的基類，提供基本的功能：

#pragma once#include <Windows.h>class MyThread{public:MyThread();virtual ~MyThread();bool Start();bool Join();bool Detach();DWORD Self();private:static DWORD WINAPI Run(PVOID pObj);virtual DWORD RumImpl() = 0;protected:static bool m_running;static bool m_detached;private:DWORD  m_tid;HANDLE m_HANDLE;};

#include "MyThread.h"#include <cstdio>#include <cstdlib>bool MyThread::m_running = false;bool MyThread::m_detached = false;MyThread::MyThread(): m_tid(0), m_HANDLE(NULL){}MyThread::~MyThread(){if (m_running){WaitForSingleObject(m_HANDLE, INFINITE);m_running = false;}if (NULL != m_HANDLE){CloseHandle(m_HANDLE);}}bool MyThread::Start(){if (NULL != m_HANDLE){printf("Thread opened.\n");return false;}m_HANDLE = CreateThread(NULL, 0, Run, this, 0, &m_tid);if (NULL == m_HANDLE){printf("CreateThread Error.\n");return false;}return true;}bool MyThread::Join(){WaitForSingleObject(m_HANDLE, INFINITE);return true;}bool MyThread::Detach(){return CloseHandle(m_HANDLE);}DWORD MyThread::Self(){return m_tid;}DWORD WINAPI MyThread::Run( PVOID pObj ){m_running = true;MyThread* lpThread = (MyThread*)pObj;return lpThread->RumImpl();}

然後，定製自己的AllenThread：

#pragma once#include "mythread.h"class AllenThread :public MyThread{public:AllenThread();virtual ~AllenThread();virtual DWORD RumImpl();};

#include "AllenThread.h"#include <cstdio>AllenThread::AllenThread(void){}AllenThread::~AllenThread(void){}DWORD AllenThread::RumImpl(){printf("Yes.It's Allen's Thread.\n");m_running = false;return 0;}

寫的還很粗糙，之後慢慢完善。
