1 std::thread传入引用值需要使用std::ref std::ref的说明: Constructs an object of the appropriate reference_wrapper type to hold a reference to elem. 其实主要是,如果要向thread传参的时候,该参数在线程内会被修改,需要用这个ref作为一个wrapper将对象包裹成为一个引
Thestd::atomic_refclass template applies atomic operations to the object it references. For the lifetime of thestd::atomic_refobject, the object it references is considered an atomic object. If one thread writes to an atomic object while another thread reads from it, the behavior is well-de...
