boost::algorithm::replace_head_copy — Replace head algorithm.

Synopsis

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

Description

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

Parameters

A substitute string

Input

An input string

N

Length of the head
