I'm using regex_grep() to search through file contents for matches. I want to read the file in blocks to keep memory use down for large files. What I want to know is whether there is some way of adding the next block of memory to the grep where the last one left off.

I'm not a regex expert, but I think the purpose of the match_flag_type::match_partial flag is to handle exactly the situation you describe. See http://www.boost.org/libs/regex/template_class_ref.htm#partial_matches (Note that partial matches will get their own docs page in the upcoming 1.31.0 release, so the above URL will change.) --Beman
