Can I catch this event?

[D. Alvarado]

Hi,
Basically, I want to run an action every time I detect a new file
appears in a particular directory. I realize I could poll the
directory every 5-10 seconds or so, but I was hoping there was a more
elegant solution. Is it possible to catch the event that a new file
appears or that the size of everything in a directory changes?

I am writing this program with gcc on a Windows platform.

Thanks in advance, Dave

Events, signals* and mutexes are an operating system issue. You
would have better luck asking in a Windows newsgroup.

*Yes, I know the C supports some signals, but in general, it is
the operating system that generates the signals.

The solution is platform specific and you'd be better served by posting
the question to one of the comp.os.ms-windows.programmer.* groups.
