Function replace_tail_copy

boost::algorithm::replace_tail_copy — Replace tail algorithm.

Synopsis

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


template<typename OutputIteratorT, typename Range1T, typename Range2T> 
  OutputIteratorT 
  replace_tail_copy(OutputIteratorT Output, const Range1T & Input, int N, 
                    const Range2T & Format);
template<typename SequenceT, typename RangeT> 
  SequenceT replace_tail_copy(const SequenceT & Input, int N, 
                              const RangeT & Format);

Description

Replace the tail of the input with the given format string. The tail is a suffix of a string of given size. If the sequence is shorter then required, whole string is considered to be the tail. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator.

	Note
	The second variant of this function provides the strong exception-safety guarantee

Parameters:

`Format`	A substitute string
`Input`	An input string
`N`	Length of the tail. For N>=0, at most N characters are extracted. For N<0, size(Input)-\|N\| characters are extracted.
`Output`	An output iterator to which the result will be copied

Returns:

An output iterator pointing just after the last inserted character or a modified copy of the input
