2. 分析错误消息“use of deleted function ‘std::atomic<bool>::atomic(const std::atomic<bool>&)’” 该错误消息表明在代码中尝试使用了std::atomic<bool>的拷贝构造函数,但这个构造函数已经被显式删除。具体来说,尝试通过拷贝来初始化std::atomic<bool&g
use of deleted function std::mutex 1、基本类 classA { std:mutex mutex; } 2、放入容器 std::vector<A>aa; aa.resize(10); 会报错 3、解决 std::shared_ptr<std::mutex> m_mutex; 长风破浪会有时,直挂云帆济沧海! 可通过下方链接找到博主 https://www.cnblogs.com/judes/p/10875138.html...
使用traits接收来自中间件的变量,调用拷贝构造函数时提示use of deleted function错误。 解释# 仔细检查对应类中定义了移动构造函数,而没有显式定义拷贝构造函数。而问题就出在这: If the class definition does not explicitly declare a copy constructor, one is declared implicitly. If the class definition declar...

error: use of deleted function ‘std::atomic<short unsigned int>::atomic(const std::atomic<short unsigned int>&) 报这个错误的主要原因是原子变量不能使用拷贝构造。 这个限制只在原子变量初始时生效,初始之后时可以使用赋值操作符的。 std::atomic<uint16_t> m_batchNumber; ...
问题分析:在倒数第3行,testPtrFunction(testPtr)会发生题目中的error 原因分析:unique_ptr指向的内存区域只能由一个unique_ptr的对象来指定。把testPtr作为传入参数的时候,就会发现有两个unique_ptr同时指向一个内存区域,实际参数testPtr和形式参数ptrHandle。
