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, int Nth, 
const std::locale & Loc = std::locale());

Description

Search for the n-th (zero-indexed) occurrence 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. For negative N, the matches are counted from the end of string.

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
