Smart Card Database Query Functions
These functions query the smart card database. They can provide a list of smart cards that are supplied by a specific user, the interfaces, and the primary service provider of a specific smart card.
When you use these functions, you can query the complete smart card database, or you can narrow your search by setting the resource manager context. The resource manager context is set by calling the SCardEstablishContext function before calling a query function.
**Note **Without a specified context, some information still might be inaccessible, due to security restrictions.
The following table shows the smart card database query functions.
