[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
