...ing socket would have blocked. You have to use a separate function such as select or poll to find out when is a good time to retry. But asynchronous sockets (as supported by Windows sockets), or the asynchronous IO pattern used in .NET, are more convenient. You call a method to start an operation, ...

...not happen at the level of generating machine code by the compiler, but by selecting the most effective algorithm: as others mentioned, you do this selection using function std::move_if_noexcept. For instance, the growth of std::vector (e.g., when we call reserve) must provide a strong exception-saf...

The other major issue is that the recursive call will get a different this value, for example: va...

...nges of the server state, and not each its observation, let alone a random selection of 10% such observations. Yes, that takes just a little bit more effort, so let's see some. I can only hope that all this evidence of incompetence, accumulated from inspecting just three lines of code, does not sp...
