See the code in attachment
I changed the code a little bit adding the OVERLAP parameter and
events to use the async method.
Now the same function returns error code 6
Error code 6 is ERROR_INVALID_HANDLE (would be nice if you'd mention
the error message as well next time when you're already using
SysErrorMessage). FindFirstChangeNotification returns a notification
handle, but ReadDirectoryChanges requires a directory handle (with
FILE_LIST_DIRECTORY priviledge), so you need to open the directory
yourself.
To add to this, the remarks section on msdn says this:
"To obtain a handle to a directory, use the CreateFile function with the
FILE_FLAG_BACKUP_SEMANTICS flag."
In addition to this you're also passing an OVERLAPPED record to
ReadDirectoryChangesW(), so you'll have to use FILE_FLAG_OVERLAPPED when
you open the directory, too.
This did it. Don't even need FindFirstChangeNotification
Thanks
Antonio.
