Windows API 封装多线程编程

将Windows 多线程API封装成一个类XThread，

//XThread.h

#pragma once
#ifdef XPLATFORM_EXPORTS
#define XPLATFORM_API __declspec(dllexport)
#else
#define XPLATFORM_API __declspec(dllimport)
#endif

class XPLATFORM_API XThread
{
public:
	bool Start();
	void Wait();
	void Suspend();
	void Resume();
	virtual void Main() = 0;
	XThread();
	~XThread();
private:
	unsigned int thread_handler = 0;
};

//XThread.cpp

#include "stdafx.h"
#include "XThread.h"
#include <process.h>
#include <windows.h>			//只是在cpp中引用
//万一外部有相同的函数名不产生冲突，只在本cpp中有效。
static void ThreadMain(void *para)
{
	XThread *th = (XThread *)para;	
	th->Main();
	_endthread();
}

XThread::XThread()
{
}


XThread::~XThread()
{
}

bool XThread::Start()
{
	thread_handler = _beginthread(ThreadMain, 0, this);
	//直接把this指针传过去，那么就可以访问成员函数了
	if ((int)thread_handler <= 0)
	{
		return false;
	}
	return true;
}

void XThread::Wait()
{
	if (thread_handler == 0) return;
	WaitForSingleObject((HANDLE)thread_handler, INFINITE);
}

void XThread::Suspend()
{
	if (thread_handler == 0) return;
	SuspendThread(HANDLE(thread_handler));
}

void XThread::Resume()
{
	if (thread_handler == 0) return;
		ResumeThread(HANDLE(thread_handler));
}

使用XThread类：

#include <iostream>
#include "XThread.h"
#include "windows.h"
using namespace std;
static char buffer[1024] = { 0 };	

class Mythread :public XThread
{
public :
	void Main()
	{
		for (;;)
		{
			int size = sizeof(buffer);
			for (int i = 0; i < size; i++)
			{	
				buffer[i] = c;
			}
			buffer[size - 1] = '\0';
			cout <<'['<< buffer<<']'<<endl;
			Sleep(500);
		}
	}
	char c;
};

int main()
{
	Mythread s1;
	Mythread s2;
	s1.c = 'A';
	s2.c = 'B';
	s1.Start();
	s2.Start();

	getchar();
	return 0;
}
