SCARD_VENDOR_ATTR (Windows Embedded CE 6.0)
1/6/2010
The SCARD_VENDOR_ATTR structure holds all information about the reader. The driver is responsible for filling in all members.
Syntax
typedef struct _VENDOR_ATTR {
struct {
USHORT Length;
UCHAR Buffer[MAXIMUM_ATTR_STRING_LENGTH];
} VendorName;
struct {
USHORT Length;
UCHAR Buffer[MAXIMUM_ATTR_STRING_LENGTH];
} IfdType;
ULONG UnitNo;
struct {
USHORT BuildNumber;
UCHAR VersionMinor;
UCHAR VersionMajor;
} IfdVersion;
struct {
USHORT Length;
UCHAR Buffer[MAXIMUM_ATTR_STRING_LENGTH];
} IfdSerialNo;
ULONG Reserved[25];
} VENDOR_ATTR, *PVENDOR_ATTR;
Members
- VendorName
Mandatory. Contains the ANSI-coded name of the vendor. Because a length field is provided, no terminating NULL character is necessary.
- IfdType
Mandatory. Contains the ANSI-coded designation of the reader, that is, the reader name.
- UnitNo
Mandatory. This is the number of this unit and should be set to the n if the driver name is "SCRn:". Because it is possible to have more than one reader of this type installed in a system, UnitNo is used to distinguish the readers.
- IfdVersion
Optional. The version number of the reader. This member can be used for support purposes. It should be maintained only if the reader allows the value to be queried.
- IfdSerialNo
Optional. The serial number of the connected reader. This field should only be maintained if the reader allows the serial number to be queried.
- Reserved
A buffer of 25 ULONG values, reserved for future use. Drivers should not use this space.
