二 测试
cpp
复制代码
#include "MyThread.hpp"
#include <vector>

}
}

{
std::vector<Thread> threads;
for (int i = 0; i < 10; ++i)
{
threads.push_back(Thread(task));
}
for (auto &t : threads)
{
t.Run();
}
for (auto &t : threads)
{
t.Join();
}
}
// int main()
// {
// Thread t1(task);
// std::cout << "name:" << t1.Name() << " time:" << t1.StartTimeStamp()
// << " isrun?? " << t1.Isrunning() << std::endl;
// t1.Run();
// std::cout << "name:" << t1.Name() << " time:" << t1.StartTimeStamp()
// << " isrun?? " << t1.Isrunning() << std::endl;
// t1.Join();
// }
