How to quickly get whether a directory has changed using C++ without a monitoring thread or process?

Question

The change includes adding or removing files in the directory, or changes of its sub-directories. Is there any windows APIs which can get thus changes? I don't have a thread or process to monitor the file system.

Answer 1

I'd try CDirectoryChangeWatcher, it wraps the windows ReadDirectoryChangesW function up so it's easier to use.

Answer 2

• FindFirstChangeNotification
• ReadDirectoryChangesW
