This is exactly what cardlock_cancel.c is doing.

Ievgenii published the complete project at https://github.com/eugmes/cardlock
The samples should work on GNU/Linux, Windows and macOS.

The other process cardlock.c is (just) used to start a PC/SC
transaction and lock the access to the card.

If someone can run the sample codes on Windows and get a working
SCardCancel() that would help.
