WebC++11 标准引入了两种智能指针:std::unique_ptr 和 std::shared_ptr。 其中,std::unique_ptr 只能拥有一个指向对象的指针,std::shared_ptr 可以拥有多个指向同一个对象的指针。 使用智能指针可以避免手动管理内存,从而减少内存泄漏的风险。 总之,内存泄漏是一种常见的编程错误,可以使用工具和编程技巧进行检测和避免。 开发者需要对内 … WebJan 6, 2024 · lock_guard/unique_lockの例を自作クラス(Wlock)で実現した例.lock_guardはさらにテンプレートを使って柔軟に書いてあるのだと思う.Read-Write Lockパターン. 前に書いたRead-Write Lockパターンを,C++標準のthreadとlock_guard, condition_variableを使って書き直してみた. どうやらC++ではポインタをできるだけ …
