1) Determines if there is a match between the regular express e and some subsequence in the target character sequence [first,last). Match results are returned in m.

2) Returns std::regex_search(str, str + std::char_traits<charT>::length(str), m, e, flags).

3) Returns std::regex_search(s.begin(), s.end(), m, e, flags).

4) The same as (1), omitting the match results.

5) Returns std::regex_search(str, str + std::char_traits<charT>::length(str), e, flags).

6) Returns std::regex_search(s.begin(), s.end(), e, flags).

Parameters

first, last - the target character range
m - the match results
str - a target character null-terminated C-style string
s - a target character std::basic_string
e - the std::regex
flags - the match flags

Return value

Returns Template:cpp if a match exists somewhere in the target sequence, Template:cpp otherwise.
