15[heading Description]
16
17`copy_n` is provided to completely replicate the standard algorithm header,
18it is preferable to use Range Adaptors and the extension functions to achieve
19the same result with greater safety.
20
21`copy_n` copies elements from `[boost::begin(rng), boost::begin(rng) + n)` to the range `[out, out + n)`
22
23[heading Definition]

25Defined in the header file `boost/range/algorithm_ext/copy_n.hpp`

27[heading Requirements]
28
29# `SinglePassRange` is a model of the __single_pass_range__ Concept.
30# `Size` is a model of the `Integer` Concept.
31# `OutputIterator` is a model of the `OutputIteratorConcept`.
32
33[heading Complexity]
34
35Linear. Exactly `n` elements are copied.
