STD::BINARY_FUNCTION(3cxx)

💅 NAME 💅

okay so this is the 3cxx manual page for std::binary_function< _Arg1, _Arg2, _Result > — the header truncates it as std::binary_fu...Arg2, _Result >(3cxx), but it's the same iconic little struct, no cap. 🫶

✨ SYNOPSIS ✨

#include <functional>

Inherited by these absolute legends:

• std::_Sp_owner_less< shared_ptr< _Tp >, weak_ptr< _Tp > >
• std::_Sp_owner_less< weak_ptr< _Tp >, shared_ptr< _Tp > >
• std::_Sp_owner_less< __shared_ptr< _Tp, _Lp >, __weak_ptr< _Tp, _Lp > >
• std::_Sp_owner_less< __weak_ptr< _Tp, _Lp >, __shared_ptr< _Tp, _Lp > >
• std::_Sp_owner_less< void, void >
• std::equal_to< _Key >
• std::equal_to< _Value >
• std::less< typename _Sequence::value_type >
• __gnu_parallel::_Multiplies< _Tp1, _Tp2, _Result >
• __gnu_parallel::_Plus< _Tp1, _Tp2, _Result >
• and std::pointer_to_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.
• typedef _Arg2 second_argument_type — second_argument_type is the type of the second argument.

🌈 Detailed Description 🌈

template<typename _Arg1, typename _Arg2, typename _Result>
struct std::binary_function< _Arg1, _Arg2, _Result >

So what is it? It's the “Helper for defining adaptable binary function objects.” 💖

💀 Deprecated 💀

Deprecated — deprecated in C++11, no longer in the standard since C++17. Not me pretending this is current, bestie — it's literally a legacy icon. 😭

first_argument_type

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

first_argument_type is the type of the first argument.

result_type

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

result_type is the return type.

second_argument_type

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

second_argument_type is the type of the second argument.
