Overview of the Smartcard device drivers technology.
To develop Smartcard device drivers, you need these headers:
For the programming guide, see Smartcard device drivers.
IOCTLs
| IOCTL_SMARTCARD_EJECT The IOCTL_SMARTCARD_EJECT request ejects the currently inserted smart card from the smart card reader. |
| IOCTL_SMARTCARD_GET_LAST_ERROR The IOCTL_SMARTCARD_GET_LAST_ERROR request retrieves the error code of the most previous operation because there is no option to return an error code immediately after an overlapped operation is complete. |
| IOCTL_SMARTCARD_SWALLOW The IOCTL_SMARTCARD_SWALLOW request causes the smart card reader to swallow the card. |
Structures
| SMARTCARD_EXTENSION The SMARTCARD_EXTENSION structure is used by both the smart card reader driver and the smart card driver library to access all other smart card data structures. |
| CLOCK_RATE_CONVERSION The CLOCK_RATE_CONVERSION structure holds a value that determines the duration of a bit of data and the corresponding maximum operating frequency that accompanies the indicated bit length. |
| OS_DEP_DATA The OS_DEP_DATA structure defines the data that is stored in the OsData member of the SMARTCARD_EXTENSION structure, which holds smart card information that is specific to the operating system. |
| PTS_DATA The PTS_DATA structure is used for protocol type selection (PTS). |
| SCARD_CARD_CAPABILITIES The SCARD_CARD_CAPABILITIES structure declaration defines the data that is stored in the CardCapabilites member of the SMARTCARD_EXTENSION structure and holds all information that is specific to the particular smart card that is currently used. |
| SCARD_READER_CAPABILITIES The SCARD_READER_CAPABILITIES structure holds state information about the smart card reader. |
| SMARTCARD_REPLY Describes the reply buffer received from the smart card. |
| SMARTCARD_REQUEST Describes the request buffer that contains data to send to the card. |
| T0_DATA The T0_DATA structure is used by the smart card driver library to process T0 I/O. |
| T1_DATA The T1_DATA structure is used by the smart card driver library to process T1 I/O. |
| VENDOR_ATTR The VENDOR_ATTR structure defines the data that is stored in the VendorAttr member of the SMARTCARD_EXTENSION structure. VENDOR_ATTR also holds information that identifies the smart card reader, such as the vendor name, unit number, and serial number. |
