线程标识类型为std::thread::id 可以通过调用std::thread对象的成员函数get_id()来直接获取。 如果std::thread对象没有与任何执行线程相关联,get_id()将返回std::thread::type默认构造值,这个值表示“无线程”。 练习代码: #include <QCoreApplication>#include<thread>#include<iostream>structrun{ ...

4.1 this_thread::get_id(): 获取当前进程ID: 4.2 this_thread::sleep_for(): 使当前线程休眠一段时间():不过往往休眠的时间会超过这个数值,可以通过更高精度的计时器验证。 4.3 this_thread::sleep_until(): 使当前线程休眠到某个时间点()。
