Defined in header <memory>
template< class ForwardIterator, class T > void uninitialized_fill( ForwardIterator first,                          ForwardIterator last,                          const T& value )

Copies the given value value to an uninitialized memory area, defined by the range [first, last). The elements in the uninitialized area are constructed using copy constructor.

Parameters

first, last	-	the range of the elements to initialize
value	-	the value to construct the elements with

Return value

(none)

Complexity

linear in the distance between first and last

Possible implementation

template<class ForwardIterator, class T> void uninitialized_fill(ForwardIterator first, ForwardIterator last, const T& value) { typedef typename std::iterator_traits<ForwardIterator>::value_type Value; for (; first != last; ++first) { ::new (static_cast<void*>(&*first)) Value(value); } }
