首先,就像在建议的评论中一样,我建议您也使用std::vector,例如,std::vector<std::thread>。下面是一个小例子,展示了它的样子: #include <iostream>#include <vector>#include <thread>using namespace std;void print(int i){ std::cout << i << std::endl;}int main(){ std::vector<std::thread>...
valarray vector ILE C++ supports reentrancy to the extent that you can safely read a single object from multiple threads simultaneously. This level of reentrancy is intrinsic. No locks or other globally allocated resources are used. However, the headers are not reentrant in these cases: A single ...

std::vector<Functor> pendingFunctors_GUARDED_BY(mutex_);// 任务队列 }; Muduo在EventLoop中,使用了Linux系统中EventFd,作为wakeupChannel_的成员。这里主要为了将线程即时唤醒处理回调任务。如果你阅读过sylar的源码应该在这里会有所感知,EventLoop::wakeup()函数其实作用和sylar中的IOManager::tickle()类似。
(c)vector<map<int,string>>? (d)shared_ptr<widget>? (e)mutex? (f)condition_variable? (g)atomic<unsigned>? Hint: This is actually a two-part question, not a seven-part question. There are only two unique answers, each of which covers a subset of the cases. ...
