= OSSEC, os_regex Library. =


Fast and simple library for regular expressions in C.
Available at http://www.ossec.net/c/os_regex/

This library is designed to be simple, but support
the most common regular expressions. It was design
with intrusion detection systems in mind, where having
all options is not crucial, but speed is.


The following expressions are supported:
    \w  ->  A-Z, a-z, 0-9 characters
    \d  ->  0-9 characters
    \s  ->  For spaces " "
    \p  ->  ()*+,-.:;<=>?[] (pontuation characters)
    \W  ->  For anything not \w
    \D  ->  For anything not \d
    \S  ->  For anything not \s
    \.  ->  For anything

       
Each regular expression can be followed by:

    +  ->  To match one or more times (eg \w+ or \d+)
    *  ->  To match zero or more times (eg \w* or \p*)

    
We also support the "^" to match at the beginning of the text,
'$" to match at the end of the text and "|" to have multiple
expressions.
