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 true if a match exists, false otherwise.
