Member Function Documentation

template<typename _Alloc>

static pointer std::allocator_traits< _Alloc >::allocate	(	_Alloc &	__a,
		size_type	__n
	)		`[inline, static, inherited]`

Allocate memory.

Parameters:

__a	An allocator.
__n	The number of objects to allocate space for.

Calls a.allocate(n)

Definition at line 345 of file bits/alloc_traits.h.

template<typename _Alloc>

static pointer std::allocator_traits< _Alloc >::allocate	(	_Alloc &	__a,
		size_type	__n,
		const_void_pointer	__hint
	)		`[inline, static, inherited]`

Allocate memory.

Parameters:

__a	An allocator.
__n	The number of objects to allocate space for.
__hint	Aid to locality.

Returns:: Memory of suitable size and alignment for n objects of type value_type

Returns a.allocate(n, hint) if that expression is well-formed, otherwise returns a.allocate(n)

__p	Pointer to memory of suitable size and alignment for Tp
__args	Constructor arguments.

Calls __a.construct(__p, std::forward<Args>(__args)...) if that expression is well-formed, otherwise uses placement-new to construct an object of type _Tp at location __p from the arguments __args...
