|| 我发现一些代码使用std :: shared_ptr在关机时执行任意清理。起初,我认为此代码可能无法工作,但随后尝试了以下操作: #include <memory> #include <iostream> #include <vector> class test { public: test() { std::cout << \"Test created\" << std::endl; } ~test() { std::cout << \"Test...

裸指针(raw pointer):传统的C++指针,直接指向内存中的某个地址,需要手动管理内存的分配和释放。 智能指针(smart pointer):如std::shared_ptr,它自动管理所指对象的生命周期,确保在适当的时候释放资源。 B:保持连接对象存活,传递std::shared_ptr 保持不断 在异步处理逻辑中,连接对象(如connection)可能在多个异步任务...
