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

2) Behaves as (1) above, omitting the match results.

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

4) Returns std::regex_match(s.begin(), s.end(), m, e, flags).

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

6) Returns std::regex_match(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, Template:cpp otherwise.
