__GNU_CXX::PROJECT2ND(3)

💖 NAME 💖

okay so bestie, meet __gnu_cxx::project2nd< _Arg1, _Arg2 > — it's an SGI extension ✨. That's it, that's the whole vibe of the name. She's a little struct with big main character energy 👑

This page lives in the Library Functions Manual, section 3, and it's part of libstdc++ 🫶

🎀 SYNOPSIS 🎀

#include <functional>

🌸 Public Types 🌸

• typedef _Arg1 first_argument_type — bestie, first_argument_type is literally just the type of the first argument 💅
• typedef _Arg2 result_type — and result_type? that's the return type, no cap 🌈
• typedef _Arg2 second_argument_type — second_argument_type is the type of the second argument, periodt ⭐

🦋 Public Member Functions 🦋

• _Arg2 operator() (const _Arg1 &, const _Arg2 &__y) const — the one and only call operator, she's doing the actual work here 😌

---

✨ Detailed Description ✨

template<class _Arg1, class _Arg2>
struct __gnu_cxx::project2nd< _Arg1, _Arg2 >

She's an SGI extension 🫶 and honestly? iconic. That's the whole description, not me gatekeeping anything 💀

💜 Member Typedef Documentation 💜

• typedef _Arg1 std::binary_function< _Arg1, _Arg2, _Arg2 >::first_argument_type [inherited] — first_argument_type is the type of the first argument 🌸
• typedef _Arg2 std::binary_function< _Arg1, _Arg2, _Arg2 >::result_type [inherited] — result_type is the return type ⭐
• typedef _Arg2 std::binary_function< _Arg1, _Arg2, _Arg2 >::second_argument_type [inherited] — second_argument_type is the type of the second argument 🦋

ngl bestie, all three of these are marked [inherited] — they're coming straight down from std::binary_function< _Arg1, _Arg2, _Arg2 > 💖
