-
- use Win32::ChangeNotification;
-
- Win32::ChangeNotification::FindFirst($Obj,$PathName,$WatchSubTreeFlag,$filter);

- =head1 DESCRIPTION
-
- This module allows the user to create a change notification event object
- in Perl. This object allows the Perl program to monitor events relating
- to files and directory trees.
-
- =head1 MEMBERS
-
- The ChangeNotification module is written entirely in C++. So here is a
- list of the members etc.(Note: no functions are exported)

- FindFirst($Obj,$PathName,$WathSubTree,$Filter)
- This is the constructor for the object. An instantiated object is
- returned in $Obj.
- Args:
- $Obj The container for the created object.
- $WatchSubTree A boolean value defining whether the subtree
- should be included.
- $Filter See the exported values below to see the options
- For this.
