Where is a reference to regex header on MSDN?

I can include this file directly now without tr1 in VS 2010 but can't find description of this file anywhere on MSDN. Where is a reference to regex header on 开发者_C百科MSDN?

The regex description on 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

You shouldn't need any specific headers beyond <regex> to include the tr1 functionality. To get start using Regular Expressions in tr1 I suggest reading: http://www.johndcook.com/cpp_regex.html
