cleanup (cleanup_function)

The cleanup attribute runs a function when the variable goes out of scope. This attribute can only be applied to auto function scope variables; it may not be applied to parameters or variables with static storage duration. The function must take one parameter, a pointer to a type compatible with the variable. The return value of the function (if any) is ignored.

If -fexceptions is enabled, then cleanup_function is run during the stack unwinding that happens during the processing of the exception. Note that the cleanup attribute does not allow the exception to be caught, only to perform an action. It is undefined what happens if cleanup_function does not return normally.

Потрудился наславу: создал 2К портов в конфигурации, вручную!

Напомнило историю с МСДН, когда гейдев пожаловался на то, что сапер тормозит: он его создал из 5000 кнопок, которые он поставил на формочку в ВинФормс.

Но самое говно-то не там, а в Кубернетисе, конечно.

предполагалось, что код будет уменьшать cos угла в два раза, но при компиляции выдает ошибки, логику большинства которых не могу понять. Ошибки указал в коде. Подскажите, что не так.

Метушня выходит на новый уровень: полноценный map в compile-time. Поддерживает как ручные функторы с перегруженным operator(), так и constexpr-лямбды. При помощи небольшой модификации возможно реализовать поддержку кортежей с произвольными типами.
