STD::POINTER_TO_BINARY_FUNCTION(3)

🌸 NAME 🌸

std::pointer_to_binary_function< _Arg1, _Arg2, _Result > — one of the adaptors for function pointers, bestie. That's literally the whole thing. It's giving ✨legacy template✨ energy.

This page lives in the Library Functions Manual, section 3. 💅

✨ SYNOPSIS ✨

okay so first you gotta pull it in:

#include <functional>

and heads up, it inherits std::binary_function< _Arg1, _Arg2, _Result > 🫶

🎀 Public Types

• typedef _Arg1 first_argument_type — first_argument_type is the type of the first argument 💖
• typedef _Result result_type — result_type is the return type, no cap
• typedef _Arg2 second_argument_type — second_argument_type is the type of the second argument 🌸

💫 Public Member Functions

• pointer_to_binary_function (_Result(*__x)(_Arg1, _Arg2)) — the constructor, it takes a pointer to a function that eats two args and hands you back a _Result
• _Result operator() (_Arg1 __x, _Arg2 __y) const — the call operator, this is the moment 🔥

🙈 Protected Attributes

• _Result(* _M_ptr )(_Arg1, _Arg2) — the actual function pointer hiding in here, protected, so don't go poking at it from outside bestie 😭

👑 Detailed Description 👑

template<typename _Arg1, typename _Arg2, typename _Result>
    class std::pointer_to_binary_function< _Arg1, _Arg2, _Result >

"One of the adaptors for function pointers." — that's the official vibe. It wraps up a plain old function pointer and lets it play nice with the rest of the function-object world. Main character energy fr fr. ⭐

💖 Member Typedef Documentation 💖

first_argument_type 🌈

template<typename _Arg1, typename _Arg2, typename _Result> typedef _Arg1
    std::binary_function< _Arg1, _Arg2, _Result >::first_argument_type
    [inherited]

first_argument_type is the type of the first argument 🍓 (inherited, iykyk)

result_type 💜

template<typename _Arg1, typename _Arg2, typename _Result> typedef _Result
    std::binary_function< _Arg1, _Arg2, _Result >::result_type [inherited]

result_type is the return type ✨ (also inherited)

second_argument_type 🦋

template<typename _Arg1, typename _Arg2, typename _Result> typedef _Arg2
    std::binary_function< _Arg1, _Arg2, _Result >::second_argument_type
    [inherited]

second_argument_type is the type of the second argument 🌸 (inherited too, slay)

and that's the page bestie!! it's part of libstdc++, served fresh from the Library Functions Manual, section 3 — Doxygen did the typing, I did the vibes. mwah 💋
