問題：
std::thread::thread(const std::thread&):嘗試引用已刪除的函式

 
#include <iostream>
#include<thread>
#include<vector>
#include<algorithm>
#include<functional>

using namespace std;


void func()
{
	cout << "from func: "<<this_thread::get_id
 
()<< endl;
}
int main()
{
	thread::id master_id;
	cout << "master id " << master_id<<endl;


	cout << "max num of thread the system support : " << thread::hardware_concurrency << endl;


	vector<thread> threads;

	thread t1(func);
	thread t2
 
(func);
	thread t3(func);
	thread t4(func);
	// 這裡有個問題一定要注意，Thread 的拷貝建構函式定義成了delete的。就不能直接被訪問，所以只能使用move來創造出一個臨時的變數來填充vector
	threads.push_back(move(t1));
	threads.push_back(move(t2));
	threads.push_back(move(t3));
	threads.push_back(move(t4));

	std::for_each(threads.begin(), threads.end(), std::mem_fn
 
(&std::thread::join));
