[Boost-users] Using regex on a file

Hello all, I would like to programmatically search a (large) binary file for a particular text string and get a boolean result back - either the string appeared or it did not. I imagine whatever I end up implementing will be platform-independent, but I'll state anyway that I am using Visual C++. My first thought was to use regex_search and pass it two stream iterators, one pointing to the beginning of the file and one representing the end of the file. Alas, this won't work since regex_search requires bidirectional iterators, which stream iterators are not. I would appreciate any suggestions as to how I can most efficiently and elegantly achieve my goal. Thank you! Dave
