POCO Simple Thread example using threadpool

thread2.cpp

// sample of using POCO's ThreadPool

#include "Poco/Runnable.h"
#include "Poco/ThreadPool.h"
#include <iostream>

using namespace std;

class Worker:public Poco::Runnable{
	public:
		Worker(int n):_id(n){}
		virtual void run() {
			cout << "i'm worker:" << _id << endl;
		}	
	private:
		int _id;		
};

int main(int argc, char **argv)
{
	Worker work1(1);
	Worker work2(2);
		
	Poco::ThreadPool threadpool;
	
	threadpool.start(work1);
	threadpool.start(work2);
	
	threadpool.joinAll();
	
	return 0;
}

thread 대신 ThreadPool 을 사용
ThreadPool 은 thread 의 container 로써 Thread 들의 lifetime 을 효율적으로 관리할 수 있도록 해준다.
