可变参数应用（C++并发编程中的joining_thread代码）

代码：

#include "X:\Work\Share\CCode\CPlatform\Base\global_c_all.h" 
using namespace lf;
using namespace std;
 
class joining_thread
{
	std::thread t;
public:
	joining_thread() noexcept = default;

	template<typename Callable, typename ... Args>
	explicit joining_thread(Callable&& func, Args&& ... args) :
		t(std::forward<Callable>(func), std::forward<Args>(args)...)
	{

	}

	explicit joining_thread(std::thread t_) noexcept :
		t(std::move(t_))
	{

	}

	joining_thread(joining_thread&& other) noexcept :
		t(std::move(other.t))
	{

	}

	joining_thread& operator=(joining_thread&& other) noexcept
	{
		if (joinable())
			join();
		t = std::move(other.t);
		return *this;
	}
	~joining_thread() noexcept
	{
		if (joinable())
			join();
	}

	void swap(joining_thread& other)noexcept
	{
		t.swap(other.t);
	}


	std::thread::id get_id() const noexcept {
		return t.get_id();
	}

	bool joinable() const noexcept
	{
		return t.joinable();
	}

	void join()
	{
		t.join();
	}

	void detach()
	{
		t.detach();
	}

	std::thread& as_thread() noexcept
	{
		return t;
	}

	const std::thread& as_thread() const noexcept
	{
		return t;
	}
};


int main()
{

	joining_thread t(std::thread([]() {
		_cout << _t("执行线程代码。");
		}));

	//t.join();

	return 0;
}
