Function erase_first

Function erase_first_copy

boost::algorithm::erase_first_copy — Erase first algorithm.

Synopsis

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


template<typename OutputIteratorT, typename Range1T, typename Range2T> 
  OutputIteratorT 
  erase_first_copy(OutputIteratorT Output, const Range1T & Input, 
                   const Range2T & Search);
template<typename SequenceT, typename RangeT> 
  SequenceT erase_first_copy(const SequenceT & Input, const RangeT & Search);

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.

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

Parameters:

`Input`	An input string
`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
