Both of these methods use polling right, I don't think there's any way to be notified
or block till there's new data or anything... you just have to keep testing the file
for new data. And sleep() or usleep() some amount of time between checks so cpu usage
don't go nuts.
you can popen ("tail -f filename", "r") and get tail to do the polling for you :) I'm
pretty sure tail -f polls..
yeh enough rambling
