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.
John.
Ah, thank you, somehow I had missed that.
