Function template ifind_nth

boost::algorithm::ifind_nth — Find n-th algorithm ( case insensitive ).

Synopsis

template<typename Range1T, typename Range2T> 
  iterator_range< typename range_result_iterator< Range1T >::type > 
  ifind_nth(Range1T & Input, const Range2T & Search, unsigned int Nth, 
            const std::locale & Loc = std::locale());

Description

Search for the n-th (zero-indexed) occurence of the substring in the input. Searching is case insensitive.

Parameters

Input

A string which will be searched.

Loc

A locale used for case insensitive comparison

Nth

An index (zero-indexed) of the match to be found.

Search

A substring to be searched for.

Returns: An iterator_range delimiting the match. Returned iterator is either Range1T::iterator or Range1T::const_iterator , depending on the constness of the input parameter.
Notes: This function provides the strong exception-safety guarantee
