c++ - 创建 vector

Question

我只是想创建一个 std::vector 线程并运行它们。

代码:

thread t1(calc, 95648, "t1");
thread t2(calc, 54787, "t2");
thread t3(calc, 42018, "t3");
thread t4(calc, 75895, "t4");
thread t5(calc, 81548, "t5");

vector<thread> threads { t1, t2, t3, t4, t5 };

错误:“function std::thread::thread(const std::thread &)”(在“C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\thread”的第 70 行声明) ) 不能被引用——它是一个被删除的函数

thread(const thread&) = delete;

似乎是什么问题？

由于线程不可复制，但可移动，我推荐以下方法:

std::vector<std::thread> threads;

threads.emplace_back(calc, 95648, "t1");
threads.emplace_back(calc, 54787, "t2");
threads.emplace_back(calc, 42018, "t3");
threads.emplace_back(calc, 75895, "t4");
threads.emplace_back(calc, 81548, "t5");
