与 C++11 多线程相关的头文件

C++11 新标准中引入了四个头文件来支持多线程编程，他们分别是<atomic> ,<thread>,<mutex>,<condition_variable>和<future>。

• <atomic>：该头文主要声明了两个类, std::atomic 和 std::atomic_flag，另外还声明了一套 C 风格的原子类型和与 C 兼容的原子操作的函数。
• <thread>：该头文件主要声明了 std::thread 类，另外 std::this_thread 命名空间也在该头文件中。
• <mutex>：该头文件主要声明了与**互斥量(mutex)**相关的类，包括 std::mutex 系列类，std::lock_guard, std::unique_lock, 以及其他的类型和函数。
• <condition_variable>：该头文件主要声明了与条件变量相关的类，包括 std::condition_variable 和 std::condition_variable_any。
• <future>：该头文件主要声明了 std::promise, std::package_task 两个 Provider 类，以及 std::future 和 std::shared_future 两个 Future 类，另外还有一些与之相关的类型和函数，std::async() 函数就声明在此头文件中。

多线程Hello World!

Example 1：

#include <iostream>
#include <thread>

void sub_task(){std::cout << "hello world" << std::endl;}

int main(int argc, char** argv )
{
	std::thread t(sub_task);
	t.join();

	system("pause");
	return 0;
}

Example 2：

#include <iostream>
#include <thread>

void output(int i,int j){std::cout << i+j << std::endl;}

int main()
{
	for (uint8_t i = 0; i < 4; i++)
	{
		std::thread t(output, i, i);
		t.detach();
	}
	system("pause");
	return 0;
}
