STD::_NOT_FN(3)

💖 NAME 💖

okay so bestie, welcome to the manual page for std::_Not_fn< _Fn > from the Library Functions Manual. The official name is std::_Not_fn< _Fn >, and the one-line description is Generalized negator. That’s the whole name section, periodt. ✨

🦋 Detailed Description 🦋

template<typename _Fn>
    class std::_Not_fn< _Fn >"Generalized negator.

That’s the detailed description, bestie. It says the class is a Generalized negator, and the template parameter is _Fn. No extra lore, no secret chapters. 🦋

Sign-off: this page came from libstdc++, and its page name is std::_Not_fn< _Fn >(3). The footer did not give a date, so there’s no date to spill. Bye bestie, go negate something generalized! 💖✨
