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.

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.

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.

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 200 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.
