SMARTCARD_EXTENSION (Windows Embedded CE 6.0)

1/6/2010

The SMARTCARD_EXTENSION structure is used by the driver to access all the other smart card data structures, and additional information. This structure is passed to all callback functions.

Syntax

typedef struct _SMARTCARD_EXTENSION {
  ULONG Version;
  VENDOR_ATTR VendorAttr;
  NTSTATUS (*ReaderFunction[16])(PSMARTCARD_EXTENSION);
  SCARD_CARD_CAPABILITIES CardCapabilities;
  ULONG LastError;
  struct {
    PULONG Information;
    PUCHAR RequestBuffer;
    ULONG RequestBufferLength;
    PUCHAR ReplyBuffer;
    ULONG ReplyBufferLength;
  } IoRequest;
  ULONG MajorIoControlCode;
  ULONG MinorIoControlCode;
  POS_DEP_DATA OsData;
  SCARD_READER_CAPABILITIES ReaderCapabilities;
  PREADER_EXTENSION ReaderExtension;
  SMARTCARD_REPLY SmartcardReply;
  SMARTCARD_REQUEST SmartcardRequest;
  T0_DATA T0;
  T1_DATA T1;
  ULONG Reserved[25];
} SMARTCARD_EXTENSION, *PSMARTCARD_EXTENSION;
