std::terminate_handler(3)

💖 NAME 💖

okay bestie, welcome to the std::terminate_handler page from the C++ Standard Libary manual 💅 this one is literally about the function-pointer type that decides what happens when termination goes down.

✨ Synopsis ✨

Defined in header <exception>

typedef void (*terminate_handler)();

std::terminate_handler is the function pointer type (pointer to function that takes no arguments and returns void), which is installed and queried by the functions std::set_terminate and std::get_terminate and called by std::terminate. no cap, that's the whole vibe 🫶

A std::terminate_handler shall terminate execution of the program without returning to the caller, otherwise the behavior is undefined. periodt — it is not supposed to come back and say "hey bestie, I'm done" 😭 that's undefined behavior territory, fr fr 💀

The C++ implementation provides a default std::terminate_handler function, which calls std::abort(). If the null pointer value is installed (by means of std::set_terminate), the implementation may restore the default handler instead.
