## Function to_lower_copy

boost::algorithm::to_lower_copy — Convert to lower case.

## Synopsis

    template<typename OutputIteratorT, typename RangeT>
      OutputIteratorT
      to_lower_copy(OutputIteratorT Output, const RangeT & Input,
                    const std::locale & Loc = std::locale());
    template<typename SequenceT>
      SequenceT to_lower_copy(const SequenceT & Input,
                              const std::locale & Loc = std::locale());

## Description

Each element of the input sequence is converted to lower case. The result is a copy of the input converted to lower case. It is returned as a sequence or copied to the output iterator.

Parameters: |

`Input` | An input range
`Loc` | A locale used for conversion
`Output` | An output iterator to which the result will be copied

Returns: | An output iterator pointing just after the last inserted character or a copy of the input
Notes: | The second variant of this function provides the strong exception-safety guarantee
