recieve signal when file written to

Hi. :) I would like to have my program watch over a particular file, and then recieve a signal (to probably wake a sleeping thread) when that file is written to by any other program.

Something like FileSystemWatcher http://msdn.microsoft.com/library/de...components.asp only in C, would be what I'm looking for.

Look up the function FindFirstChangeNotification() in the win32 API. The documentation of that function, and related ones, should be enough to get you started

Perfect, did exactly what I needed. Thank you :)
