std::_Func...on_pointer(3)

📦 version 4.4.0, in nixpkgs unstable

✨ okay so hi bestie, welcome to std::_Func...on_pointer(3) — yes that truncated title is real, and this whole page is from the Library Functions Manual. It’s giving deeply niche libstdc++ lore, but we’re keeping every crumb. 💅

🎀 NAME 🎀

std::_Function_to_function_pointer — turns a function type into a function pointer type. That’s the whole plot, no cap. ✨

🌸 SYNOPSIS 🌸

🌟 Public Types 🌟

  • typedef _Tp type — the public type, exactly as listed. No extra seasoning. 🫶

💖 Detailed Description 💖

okay so the actual template situation is this, bestie:

template<typename _Tp, bool _IsFunctionType = is_function<_Tp>::value>
       struct std::_Function_to_function_pointer< _Tp, _IsFunctionType >

And what does it do? It turns a function type into a function pointer type. That’s the whole serve. 🦋

The struct std::_Function_to_function_pointer< _Tp, _IsFunctionType > situation is right there, and Definition at line 242 of file tr1_impl/functional. Very “you are here” energy. 📍
