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.
