Win32::ChangeNotify
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 ChangeNotify object for
a specified path and indicates how it should be monitored:
$ntfy = Win32::ChangeNotify->new(path,subtree,events); $ntfy->wait or warn "Something has failed: $!");
The function returns a reference to the object as $ntfy. path 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 eventsparameter indicates the type of
events that 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.
