How to watch and read a file that another process is appending to?

can you please answer this question that I posted on
When I add a watcher to read a file and all data has been read
then I do get a call back that there is data to read, but read(2)
returns 0 (EOF). At that point I have to stop the watcher or else it
will continue to tell me that there is something to read. However, if I
stop the watcher and then some other process appends data to that file
then I'll never see it.
What is the correct way to get notified that there is
additional/appended data in a file that can be read when before I
already read till the end?
