## 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>.
