Re: [Boost-users] logfile write/poll mechanism

The general technique is to read to the end of the file, then periodically check the file's size to see if it's grown; if so, keep reading (possibly doing an explicit seek to the point you were at when you last saw EOF, to reset any internal flags) until you get EOF again.

This is basically what the Unix command "tail -f" does. If you're on Unix you may want to use it; if you're not you may want to look at the source for ideas.

Thanks Scott. I'm on Unix atm, but it has to be crossplatform eventually. I'll look into the tail source. Thijs
