Thread.h
#ifndef _THREAD_H_
#define _THREAD_H_

#include <pthread.h>
#include <boost/function.hpp>

class Thread
{
public:
	typedef boost::function<void ()> ThreadFunc;
	explicit Thread(const ThreadFunc& func);

	void Start();
	void Join();

	void SetAutoDelete(bool autoDelete);

#endif // _THREAD_H_

Thread.cpp

#include "Thread.h"
#include <iostream>
using namespace std;


Thread::Thread(const ThreadFunc& func) : func_(func), autoDelete_(false)
{
}

void Thread::Start()
{
	pthread_create(&threadId_, NULL, ThreadRoutine, this);
}

void Thread::Join()
{
	pthread_join(threadId_, NULL);
}

void* Thread::ThreadRoutine(void* arg)
{
	Thread* thread = static_cast<Thread*>(arg);
	thread->Run();
	if (thread->autoDelete_)
		delete thread;
	return NULL;
}

void Thread::SetAutoDelete(bool autoDelete)
{
	autoDelete_ = autoDelete;
}

void Thread::Run()
{
	func_();
}

Thread_Test.cpp

#include "Thread.h"
#include <boost/bind.hpp>
#include <unistd.h>
#include <iostream>
using namespace std;

class Foo
{
public:
	Foo(int count) : count_(count)
	{
	}

	void MemberFun()
	{
		while (count_--)
		{
			cout<<"this is a test ..."<<endl;
			sleep(1);
		}
	}

	void MemberFun2(int x)
	{
		while (count_--)
		{
			cout<<"x="<<x<<" this is a test2 ..."<<endl;
			sleep(1);
		}
	}

	int count_;
};

void ThreadFunc()
{
	cout<<"ThreadFunc ..."<<endl;
}

void ThreadFunc2(int count)
{
	while (count--)
	{
		cout<<"ThreadFunc2 ..."<<endl;
		sleep(1);
	}
}


int main(void)
{
	Thread t1(ThreadFunc);
	Thread t2(boost::bind(ThreadFunc2, 3));
	Foo foo(3);
	Thread t3(boost::bind(&Foo::MemberFun, &foo));
	Foo foo2(3);
	Thread t4(boost::bind(&Foo::MemberFun2, &foo2, 1000));

	t1.Start();
	t2.Start();
	t3.Start();
	t4.Start();

	t1.Join();
	t2.Join();
	t3.Join();
	t4.Join();


	return 0;
}

不采用面向对象的编程风格,使用boost bind/function来实现,这就是基于对象的编程风格。
