...

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.

The best solution I can come up with is using some sort of double-buffering scheme, but that would take an awful lot of memory copies and searching some text multiple times. Both things I would prefer to avoid.

What can I do?

Have you looked at the partial match examples - there is one that searches a file in chunks.

Ah, thank you, somehow I had missed that. --Brendan
