- [heading Prototype]
- ``
- template<class SinglePassRange, class Size, class OutputIterator>
- OutputIterator copy_n(const SinglePassRange& rng, Size n, OutputIterator out);
- ``
- [heading Description]
- `copy_n` is provided to completely replicate the standard algorithm header,
- it is preferable to use Range Adaptors and the extension functions to achieve
- the same result with greater safety.
- `copy_n` copies elements from `[boost::begin(rng), boost::begin(rng) + n)` to the range `[out, out + n)`
- [heading Definition]
- Defined in the header file `boost/range/algorithm_ext/copy_n.hpp`
- [heading Requirements]
- # `SinglePassRange` is a model of the __single_pass_range__ Concept.
- # `Size` is a model of the `Integer` Concept.
- # `OutputIterator` is a model of the `OutputIteratorConcept`.
- [heading Complexity]
- Linear. Exactly `n` elements are copied.
