Where is the regex header link on MSDN?

Question

I can include this file right now without tr1 in VS 2010, but I cannot find a description of this file anywhere on MSDN. Where is the regex header link in MSDN?

Answer 1

Description of regular expressions in MSDN:

http://msdn.microsoft.com/en-us/library/bb982382.aspx

Basically, you create basic_regex objects, then call the regex_match or regex_replace functions

Answer 2

<regex>, tr1. tr1, : http://www.johndcook.com/cpp_regex.html
