Webs − It is a string with the target sequence. rgx − It is a basic_regex object to match. flags − It is used to control how rgx is matched. m − It is an object of a match_results type. Return Value It returns true if rgx is matched against the target sequence. false otherwise. Exceptions No-noexcept − this member function never throws exceptions.
