template<typename InIter, typename Sent1, typename FwdIter, typename Sent2>
hpx::parallel::util::in_out_result<InIter, FwdIter> uninitialized_move(InIter first1, Sent1 last1, FwdIter first2, Sent2 last2)# Moves the elements in the range, defined by [first, last), to an uninitialized memory area beginning at dest. If an exception is thrown during the initialization, some objects in [first, last) are left in a valid but unspecified state.
The assignments in the parallel uninitialized_move algorithm invoked without an execution policy object will execute in sequential order in the calling thread.
Note
Complexity: Performs exactly last - first assignments.
- Template Parameters
InIter – The type of the source iterators used (deduced). This iterator type must meet the requirements of an input iterator.
Sent1 – The type of the source sentinel (deduced). This sentinel type must be a sentinel for InIter.
FwdIter – The type of the iterator representing the destination range (deduced). This iterator type must meet the requirements of a forward iterator.
Sent2 – The type of the source sentinel (deduced). This sentinel type must be a sentinel for InIter2.
- Parameters
first1 – Refers to the beginning of the sequence of elements that will be moved from
last1 – Refers to sentinel value denoting the end of the sequence of elements the algorithm will be applied
first2 – Refers to the beginning of the destination range.
last2 – Refers to sentinel value denoting the end of the second range the algorithm will be applied to.
- Returns
The uninitialized_move algorithm returns an in_out_result<InIter, FwdIter>. The uninitialized_move algorithm returns an input iterator to one past the last element moved from and the output iterator to the element in the destination range, one past the last element moved.
