1) Constructs a std::regex_iterator object i as if by std::regex_iterator<BidirectionalIterator, CharT, traits> i(first, last, e, flags), and uses i to enumerate through all of the matches m of type std::match_results<BidirectionalIterator> that occur within the sequence [first,last ).

2) Same as (1).

3) Constructs an empty string result of type std::basic_string<CharT, ST, SA> and calls std::regex_replace(std::back_inserter(result), s.begin(), s.end(), e, fmt, flags).

4) Same as (3).

5) Constructs an empty string result of type std::basic_string<CharT> and calls std::regex_replace(std::back_inserter(result), s, s + std::char_traits<CharT>::length(s), e, fmt, flags).

6) Same as (5).

[edit] Parameters

fmt

-

a regex replacement format string

s

-

flags

-

[edit] Return value
