Re: [Dev-C++] file modification time

[Per W. <pw...@ia...>]

Directory updates are a OS-related thing, and not so much we can do
anything about.

Maybe you should explain exactly why it is important to check the file
modify time. Isn't it enough for the B app to just check size and read the
new information - similar to the "tail" program.

Also, remember that for Windows you can add a supervision subscription for
a file or director and get events when something happens with the file
without constantly polling the file.
