[section:remove_copy_if remove_copy_if]

[heading Prototype]

``
template<class ForwardRange, class Outputiterator, class UnaryPred>
OutputIterator
remove_copy_if(ForwardRange& rng, OutputIterator out, UnaryPred pred);

template<class ForwardRange, class OutputIterator, class UnaryPred>
OutputIterator
remove_copy_if(const ForwardRange& rng, OutputIterator out, UnaryPred pred);
``

[heading Description]

`remove_copy_if` copied all of the elements `x` from `rng` for which `pred(x)` is `false`.

[heading Definition]

Defined in the header file `boost/range/algorithm/remove_copy_if.hpp`

[heading Requirements]

* `ForwardRange` is a model of the __forward_range__ Concept.
* `ForwardRange` is mutable.
* `UnaryPred` is a model of the `UnaryPredicateConcept`.

[heading Complexity]

Linear. `remove_copy_if` performs exactly `distance(rng)` comparisons with UnaryPred.
