Function Documentation

pair() [1/2]

template<typename _T1 , typename _T2 >

pair ( _T1  , _T2    ) -> pair< _T1, _T2 >

related

Two pairs of the same type are equal iff their members are equal.

pair() [2/2]

template<class _T1 , class _T2 >

template<typename... _Args1, typename... _Args2>

constexpr std::pair< _T1, _T2 >::pair ( piecewise_construct_t  , tuple< _Args1... >  __first, tuple< _Args2... >  __second  )

inlineconstexpr

"piecewise construction" using a tuple of arguments for each member.

Parameters

__first	Arguments for the first member of the pair.
__second	Arguments for the second member of the pair.

The elements of each tuple will be used as the constructor arguments for the data members of the pair.

Definition at line 1802 of file tuple.

__addressof()

template<typename _Tp >

constexpr _Tp * std::__addressof ( _Tp &  __r )

related

A convenience wrapper for creating a pair from two objects.

Parameters

__x	The first object.
__y	The second object.

Returns

A newly-constructed pair<> object of the appropriate type.

The C++98 standard says the objects are passed by reference-to-const, but C++03 says they are passed by value (this was LWG issue #181).

Since C++11 they have been passed by forwarding reference and then forwarded to the new members of the pair. To create a pair with a member of reference type, pass a reference_wrapper to this function.
