【c++】线程使用

普通Thread的调用方式，要传递一个方法进去，进行调用，查了下win和linux是如此设计，所以thread也这样。这点与java不同

void pause_thread(int n) {

	this_thread::sleep_for(chrono::seconds(n));
	cout << "pause of" << n << "seconds ended";

thread t(hello);
	cout << "id:"<<t.hardware_concurrency << endl;

	cout << "native_handle" << t.native_handle()<<endl;
	t.join();

	thread a(hello);
	a.detach();


	thread threads[5];
	cout << "Spawning 5 threads...\n";
	for (int i = 0; i < 5; i++)
	{
		threads[i] = thread(pause_thread, i + 1);
	}
	cout << "Done spawning threads.Now waiting for them to join:\n";
	for (auto& thread : threads) {
		thread.join();
	}
	cout << "All threads joined!\n";
