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.

Detailed Description

Constant definitions for the std regex library.

This is an internal header file, included by other library headers. Do not attempt to use it directly. Instead, include <regex>.
