分析CppCrash(进程崩溃) 进程崩溃指C/C++运行时崩溃。FaultLogger模块提供进程崩溃故障检测、日志采集、日志存储、日志上报的能力,为开发者提供详细的维测日志以辅助故障定位。 本……欲了解更多信息欢迎访问华为HarmonyOS开发者官网
HAP依赖HAR A,HAR A依赖HAR B。HAP能否调用HAR B提供的接口?如果不支持间接依赖HAR,设计的原因是什么? 通过resourceManager.getStringResource接口获取HSP资源文件报“Resource id invalid”错误 HAP/HAR/HSP的关系是什么?是否都可以声明注册Ability和Page?三种类型分别推荐哪些的使用场景?选择原则是什么 如何正确引...

当输入超出了预分配的空间大小,就会覆盖该空间之后的一段存储区域,这就叫Heap Corruption。这通常也被用作黑客攻击的一种手段,因为如果在该空间之后的那段存储区域如果是比较重要的数据,就可以利用Heap Corruption来把这些数据修改掉了,后果当然可想而知了。 在VC里面,用release模式编译运行程序的时候,堆分配(Heap a...

Let’s start with a very simple string class which only holds a pointer to a heap-allocated block of memory: #include <cstring> #include <algorithm> class string { char* data; public: string(const char* p) { size_t size = strlen(p) + 1; data = new char[size]; memcpy(data, p...
