std::regex_constants - ISO C++-0x entities sub namespace for regex.
SYNOPSIS¶
5.1 Regular Expression Syntax Options¶
enum __syntax_option { _S_icase, _S_nosubs,
_S_optimize, _S_collate, _S_ECMAScript,
_S_basic, _S_extended, _S_awk, _S_grep,

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 }
This is a bitmask type indicating regex matching rules. enum
