5.2 Matching Rules

Matching a regular expression against a sequence of characters [first, last) proceeds according to the rules of the grammar specified for the regular expression object, modified according to the effects listed below for any bitmask elements set.

enum  __match_flag {
  _S_not_bol, _S_not_eol, _S_not_bow, _S_not_eow,
  _S_any, _S_not_null, _S_continuous, _S_prev_avail,
  _S_sed, _S_no_copy, _S_first_only, _S_match_flag_last
}
 
enum  match_flag_type : unsigned int {
  match_default, match_not_bol, match_not_eol, match_not_bow,
  match_not_eow, match_any, match_not_null, match_continuous,
  match_prev_avail, format_default, format_sed, format_no_copy,
  format_first_only
}
 
constexpr match_flag_type operator& (match_flag_type __a, match_flag_type __b)
 
constexpr match_flag_type operator| (match_flag_type __a, match_flag_type __b)
 
constexpr match_flag_type operator^ (match_flag_type __a, match_flag_type __b)
