__GNU_CXX::SELECT2ND(3cxx)

🌸 NAME 🌸

okay so this is the page for __gnu_cxx::select2nd< _Pair >, living in the 3cxx manual. The entire NAME vibe is: An SGI extension . — yes bestie, that's the whole flex.

---

✨ SYNOPSIS ✨

#include <functional>

It inherits std::_Select2nd< _Pair >.

🎀 Public Types 🎀

• typedef _Pair argument_type — argument_type is the type of the argument. 💖
• typedef _Pair::second_type result_type — result_type is the return type. ✨

💅 Public Member Functions 💅

Two operator() overloads, both const, both iconic:

• _Pair::second_type & operator() (_Pair &__x) const — the version that takes _Pair &__x and hands back _Pair::second_type &. 🫶
• const _Pair::second_type & operator() (const _Pair &__x) const — the version that takes const _Pair &__x and hands back const _Pair::second_type &. 👑

🦋 Detailed Description 🦋

The template shape is exactly:

template<class _Pair>
    struct __gnu_cxx::select2nd< _Pair >

And the description text is literally An SGI extension . — yep, with that space before the period, and I am not editing the sacred text. 💅

💖 Member Typedef Documentation 💖

Both of these are marked [inherited], and both come through std::unary_function< _Pair , _Pair::second_type >. First up:

typedef _Pair  std::unary_function< _Pair , _Pair::second_type
     >::argument_type [inherited]

argument_type is the type of the argument — that's the whole note. 🌸

Next one:

typedef _Pair::second_type  std::unary_function< _Pair , _Pair::second_type
     >::result_type [inherited]

result_type is the return type — simple, clean, slay. ✨

So don't @ me, @ Doxygen. 😭

okay bye bestie — source/version situation is libstdc++, the footer string is exactly libstdc++__gnu_cxx::select2nd< _Pair >(3cxx), and there is no separate date hanging out on this footer, so I'm not inventing one. That's the whole receipt, periodt. 💅✨
