This structure contains tuple information passed to the CardGetTupleData function.
typedef struct { CARD_SOCKET_HANDLEhSocket;UINT16fAttributes;UINT8 uDesiredTuple;UINT8uTupleOffset;UINT16 fFlags;UINT32 uLinkOffset;UINT32uCISOffset;UINT16 uBufLen;UINT16 uDataLen;} CARD_DATA_PARMS, *PCARD_DATA_PARMS;
Members
- hSocket
Handle to a socket and function pair. - fAttributes
First bit set means return link tuples. - uDesiredTuple
Specifies the desired tuple code. If it is 0xFF, the first tuple encountered is returned. - uTupleOffset
Specifies an offset into tuple data. - fFlags
Used by card services, value must be preserved. - uLinkOffset
Specifies a tuple link offset used internally by card services. A driver must maintain this value between calls to tuple functions. - uCISOffset
Specifies card information structure (CIS) state information used internally by card services. A driver must maintain this value between calls to tuple functions. - uBufLen
Specifies the length, in maximum number of bytes, of tuple data. - uDataLen
Specifies the length, in actual number of bytes, of tuple data.
Remarks
Because this structure is similar to the CARD_TUPLE_PARMS structure, a driver can use a single CARD_DATA_PARMS structure for all calls to the CardGetFirstTuple, CardGetNextTuple, and CardGetTupleData functions.
Requirements
OS Versions: Windows CE 1.0 and later.
Header: Cardsv2.h.
