| |
| [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. |
