## Function ierase_first_copy

boost::algorithm::ierase_first_copy — Erase first algorithm ( case insensitive ).

## Synopsis

    // In header: <boost/algorithm/string/erase.hpp>

    template<typename OutputIteratorT, typename Range1T, typename Range2T>
      OutputIteratorT
      ierase_first_copy(OutputIteratorT Output, const Range1T & Input,
                        const Range2T & Search,
                        const std::locale & Loc = std::locale());
    template<typename SequenceT, typename RangeT>
      SequenceT ierase_first_copy(const SequenceT & Input, const RangeT & Search,
                                  const std::locale & Loc = std::locale());

## Description

Remove the first occurrence of the substring from the input. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator. Searching is case insensitive.

Parameters: |
`Input` | An input string
`Loc` | A locale used for case insensitive comparison
`Output` | An output iterator to which the result will be copied
`Search` | A substring to be searched for
Returns: | An output iterator pointing just after the last inserted character or a modified copy of the input
Notes: | The second variant of this function provides the strong exception-safety guarantee
