These functions are necessary to make some smartcard-based programs work. They rely on the "SmartCard Database", which can be found in the windows registry, at \`HKLM\\SOFTWARE\\Microsoft\\Cryptography\\Calais\\SmartCards\`. I have added extensive unit tests and validated the implementation with a real application (an internal program based on Atos CardOS). As this is my first PR here, please don't hesitate to tell me if something's wrong! I was wondering if the database-related code should be moved to a dedicated file `winscard-database.c`? same for the tests?), let me know what you think. -- v4: winscard: Implement SCardGetCardTypeProviderNameA winscard: Implement SCardListCardsA winscard: Implement SCardGetCardTypeProviderNameW https://gitlab.winehq.org/wine/wine/-/merge_requests/10751
