Win32::ChangeNotification
This module provides access to Win32 change-notification objects, letting you monitor events relating to files and directory trees. The constructor for this class is new, which creates a ChangeNotification object for a specified directory and indicates how it should be monitored:
$ntfy = Win32::ChangeNotification->new(directory, subtree, filter);
The function returns a reference to the object as
$ntfy. directory is the pathname of the directory to monitor. subtree is a Boolean value that, if true, forces the object to monitor all subdirectories of the object's path. The filter parameter indicates what type of events will trigger a notification. It can be one of the following string values:
| Value | Description |
|---|---|
| ATTRIBUTES | Any attribute change |
| DIR_NAME | Any directory name change |
| FILE_NAME | Any filename change (creating/deleting/renaming) |
| LAST_WRITE | Any change to a file's last write time |
| SECURITY | Any security descriptor change |
| SIZE | Any change in a file's size |
The following methods are used on notification objects created by new:
