creating a file sliding window

[Ryan]

What I want to do is run tcpdump continuously in the background and dump
to a file. Then, while tcpdump is working, I'd like to grab arbitrary chunks
of the open dump file and parse pieces at the head of the file. After I'm
done parsing I'd like to delete them from the front of the file, creating
a sort of sliding window effect.

What would be the best way to do this?
