Hi,
is a file monitor feature planned for boost.filesystem? I have been looking for a platform independent solution, but there is none (except in toolkits like Qt). Also, so far only inotify (a subsystem in the Linux kernel) can tell me when a file is closed after writing, which is absolutely necessary when watching a plugins/ directory, for example (you don't want to touch the plugins when they're only halfway copied). Several tools watch the plugin directory, but don't care if the plugins are being written or are fully there already. This can lead to instabilities.
I think it is only logical to add this to boost.filesystem, something like set_monitor_callback(pathname, function_object);
any thoughts?
It's an interesting idea.
If you'd care to design such a feature, I'd be very interested in working with you. Right now all my filesystem effort is going into version 3 work and keeping up with bug reports. So I don't have the time to research how it could be specified such that it can be implemented on both Windows and POSIX systems.
At the least, please submit a Boost Trac feature request, so the idea doesn't get lost. Thanks, --Beman
