No it'll not return the name of the file that was changed/added. The
underlying API functions do not support that.
The return values will be
+1 The object is signalled
-1 The object is an abandoned mutex
0 Timed out
undef An error occurred
See
perldoc Win32::IPC
So, your process gets notified if something happens in the directory,
it has to find out what was it by itself.

It's just that in the mess on my table ... and in my brain
I can't find it.
