Function Documentation

◆ align()

void * std::align	(	size_t	__align,
		size_t	__size,
		void *&	__ptr,
		size_t &	__space
	)

inlinenoexcept

Fit aligned storage in buffer.

This function tries to fit __size bytes of storage with alignment __align into the buffer __ptr of size __space bytes. If such a buffer fits then __ptr is changed to point to the first byte of the aligned storage and __space is reduced by the bytes used for alignment.

C++11 20.6.5 [ptr.align]

Parameters

__align	A fundamental or extended alignment value.
__size	Size of the aligned storage required.
__ptr	Pointer to a buffer of __space bytes.
__space	Size of the buffer pointed to by __ptr.

Returns: the updated pointer if the aligned storage fits, otherwise nullptr.

Definition at line 62 of file align.h.

◆ uninitialized_copy()

template<typename _InputIterator , typename _ForwardIterator >

_ForwardIterator std::uninitialized_copy	(	_InputIterator	__first,
		_InputIterator	__last,
		_ForwardIterator	__result
	)

inline

Copies the range [first,last) into result.

Parameters

__first	An input iterator.
__last	An input iterator.
__result	An output iterator.

Returns: __result + (__first - __last)

Like copy(), but does not require an initialized output range.

Definition at line 126 of file stl_uninitialized.h.

Referenced by __gnu_parallel::parallel_sort_mwms_pu(), and std::uninitialized_move().

◆ uninitialized_copy_n()

template<typename _InputIterator , typename _Size , typename _ForwardIterator >

_ForwardIterator std::uninitialized_copy_n	(	_InputIterator	__first,
		_Size	__n,
		_ForwardIterator	__result
	)

inline

Copies the range [first,first+n) into result.

Parameters

__first	An input iterator.
__n	The number of elements to copy.
__result	An output iterator.

Returns: __result + __n

Like copy_n(), but does not require an initialized output range.

Definition at line 872 of file stl_uninitialized.h.

◆ uninitialized_default_construct()

template<typename _ForwardIterator >

void std::uninitialized_default_construct	(	_ForwardIterator	__first,
		_ForwardIterator	__last
	)

inline

Default-initializes objects in the range [first,last).

Parameters

__first	A forward iterator.
__last	A forward iterator.

Definition at line 900 of file stl_uninitialized.h.

◆ uninitialized_default_construct_n()

template<typename _ForwardIterator , typename _Size >

_ForwardIterator std::uninitialized_default_construct_n	(	_ForwardIterator	__first,
		_Size	__count
	)

inline

Default-initializes objects in the range [first,first+count).

Parameters

__first	A forward iterator.
__count	The number of objects to construct.

Returns: __first + __count

Definition at line 914 of file stl_uninitialized.h.

◆ uninitialized_fill()

template<typename _ForwardIterator , typename _Tp >

void std::uninitialized_fill	(	_ForwardIterator	__first,
		_ForwardIterator	__last,
		const _Tp &	__x
	)

inline

Copies the value x into the range [first,last).

Parameters

__first	An input iterator.
__last	An input iterator.
__x	The source value.

Returns: Nothing.

Like fill(), but does not require an initialized output range.

Definition at line 201 of file stl_uninitialized.h.

◆ uninitialized_fill_n()

template<typename _ForwardIterator , typename _Size , typename _Tp >

_ForwardIterator std::uninitialized_fill_n	(	_ForwardIterator	__first,
		_Size	__n,
		const _Tp &	__x
	)

inline

Copies the value x into the range [first,first+n).

Parameters

__first	An input iterator.
__n	The number of copies to make.
__x	The source value.

Returns: Nothing.

Like fill_n(), but does not require an initialized output range.

Definition at line 273 of file stl_uninitialized.h.

◆ uninitialized_move()

template<typename _InputIterator , typename _ForwardIterator >

_ForwardIterator std::uninitialized_move	(	_InputIterator	__first,
		_InputIterator	__last,
		_ForwardIterator	__result
	)

inline

Move-construct from the range [first,last) into result.

Parameters

__first	An input iterator.
__last	An input iterator.
__result	An output iterator.

Returns: __result + (__first - __last)

◆ uninitialized_move_n()

template<typename _InputIterator , typename _Size , typename _ForwardIterator >

pair< _InputIterator, _ForwardIterator > std::uninitialized_move_n	(	_InputIterator	__first,
		_Size	__count,
		_ForwardIterator	__result
	)

inline

Move-construct from the range [first,first+count) into result.

Parameters

__first	An input iterator.
__count	The number of objects to initialize.
__result	An output iterator.

Returns: __result + __count

Definition at line 971 of file stl_uninitialized.h.

◆ uninitialized_value_construct()

template<typename _ForwardIterator >

void std::uninitialized_value_construct	(	_ForwardIterator	__first,
		_ForwardIterator	__last
	)

inline
