I need to write a C++ application that should read firewall status of Windows, and then need to keep an eye continuously if admin/someuser changes the firewall status (lets say when my program was started firewall was disabled and after sometime Admin enabled it).
To implement this, I have created a thread that periodically(10 seconds) poll the code that checks Windows firewall status, but this doesn't look an efficient solution to me as continuous polling is required.
Is there a way to get event automatically in my program if firewall status changes (for example, FindFirstChangeNotification, using this I can get notification if any change in directory)? This will avoid continuous polling and will make program more efficient I think.
Any help is appreciated.
