How to use \\?PnP?\Notification to get the card status change when calling SCardGetStatusChange API using a card reader

Question

I want to detect card insert/remove event in a card reader without having to poll using VC++.

When I use \\?PnP?\Notification in SCardGetStatusChange API. I get the result as 0x80100009 - the specified reader name is not recognised and the EventState always remains 0.

Also can someone point to some samples on how I can listen to \\?PnP?\Notification event and proceed accordingly.
