If a function has more than one final overrider, the program is ill-formed: structA{virtualvoidf();};structVB1:virtualA{voidf();// overrides A::f};structVB2:virtualA{voidf();// overrides A::f};// struct Error : VB1, VB2// {// // Error: A::f has two final overriders in...
上面是安装了mingw以后在windows的powershell下的help结果,可以知道它专门针对[binary files]二进制文件,主要是展示它的段大小,如果没有给出目标文件,它就会自动查找当前目录是否有a.out文件。来看一下使用: PS D:\Desktop> g++ hello.cpp -o hello PS D:\Desktop> size hello.exe text data bss dec hex fil...
类的多态(运行时多态)一定要看看《深度探索CPP对象模型》这本书,stack overflow上有一个帖子深度讨论了类的多态、虚继承这些,讲到了构造析构过程中vptr的变化,然后可以自己去适当理解为什么虚函数的具体调用依赖于构造析构的当前进度(链接:https://stackoverflow.com/questions/6258559/what-is-the-vtt-for-a-class...

ThreadPool is used as a default task queue, and the default thread count is 8, or std::thread::hardware_concurrency(). You can change it with CPPHTTPLIB_THREAD_POOL_COUNT.If you want to set the thread count at runtime, there is no convenient way... But here is how....

Any other type of pointer will be passed as a pointer directly, which may be what you want, but may not be. For any type that isn't well converted by the library, use uintptr to send its address. Note also that floating points are explicitly unsupported. Note that slices are not well...
While tasks specify what actions have to be executed, executors are worker-objects that specify where and how to execute tasks. Executors spare applications the tedious management of thread pools and task queues. Executors also decouple those concepts away from application code, by providing a ...
🙂 Why does this media codec suddenly affect the operation of the Edge browser in such a dramatic way? And why does it matter it was installed 'manually'? Is it now part of any of the standard MS components?
What is more, with the widespread deployment of ASLR, code pointers are randomized and cannot be determined until runtime. Therefore, the results of these attack-critical operations with code pointers are also random and make program execution unpredictable. These may be a chance that a developer...
