c++ program to watch directory for alterations

Question

I am looking for a way to make a program in C or C++ that detects if there was any files altered, renamed, moved or deleted in a specified directory for Linux systems. Is there a way to do that?

Answer 1

You want inotify (and its man page.)

Answer 2

Look into inotify, I think it's still current.

You can also use a wrapping API, such as glib's GIO GFileMonitor.

Answer 3

Program against FAM. On current Linux systems this service is provided by gamin or a similar application.
