Regular Expression Syntax

There are two types of regular expressions: regex (OS_Regex) and sregex (OS_Match).

Regex (OS_Regex) syntax

This is a fast and simple library for regular expressions in C.

This library is designed to be simple while still supporting the most common regular expressions.

Supported expressions

This is faster than OS_Regex, but only supports simple string matching and the following special characters.
