The following table shows the smart card reader driver IOCTLs with a description of the purpose of each.

Programming element	Description
IOCTL_SMARTCARD_CANCEL_BLOCKING	This code cancels any calls to the smart card reader driver's XXX_IOControl (Device Manager) call that are blocking, such as IOCTL_SMARTCARD_IS_ABSENT and IOCTL_SMARTCARD_IS_PRESENT.
IOCTL_SMARTCARD_EJECT	This code requests a smart card reader driver to eject the currently inserted smart card from the smart card reader.
IOCTL_SMARTCARD_GET_ATTRIBUTE	This code queries smart card and smart card reader attributes.
IOCTL_SMARTCARD_GET_STATE	This code retrieves the current status of the smart card reader.
IOCTL_SMARTCARD_IS_ABSENT	This code is used to wait for card removal.
IOCTL_SMARTCARD_IS_PRESENT	This code is used to wait for card insertion.
IOCTL_SMARTCARD_POWER	This code is used to issue various power operations on a smart card.
IOCTL_SMARTCARD_RESET_EVENTS	This code is used to clear out any events that may have been set before.
IOCTL_SMARTCARD_SET_ATTRIBUTE	This code sets various attributes in the smart card reader driver.
IOCTL_SMARTCARD_SET_PROTOCOL	This code sets the protocol to be used with the currently inserted card.
IOCTL_SMARTCARD_SWALLOW	This causes the smart card reader to assume there is a non-powered card in the reader and the card is in position for use.
