CARD_DATA_PARMS

This structure contains tuple information passed to the CardGetTupleData function.

Syntax

typedef struct {
CARD_SOCKET_HANDLE hSocket;
UINT16 fAttributes;
UINT8 uDesiredTuple;
UINT8 uTupleOffset;
UINT16 fFlags;
UINT32 uLinkOffset;
UINT32 uCISOffset;
UINT16 uBufLen;
UINT16 uDataLen;
} CARD_DATA_PARMS, *PCARD_DATA_PARMS;

Members

hSocket

Handle to a socket and function pair.

fAttributes

[IN] Specify TUPLE_RETURN_LINKS to return link tuples. The first bit is 1.

uDesiredTuple

[IN] Specifies the desired tuple code. If it is 0xFF, the first tuple encountered is returned.

uTupleOffset

[IN] Specifies an offset into tuple data.

fFlags

[IN/OUT] Specifies flags used internally by Card Services. A driver must maintain this value between calls to tuple functions.

uLinkOffset

[IN/OUT] Specifies a tuple link offset used internally by Card Services. A driver must maintain this value between calls to tuple functions.

uCISOffset

[IN/OUT] Specifies CIS state information used internally by Card Services. A driver must maintain this value between calls to tuple functions.

uBufLen

[IN] Specifies the length, in maximum number of bytes, of tuple data.

uDataLen

[OUT] 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 could use a single CARD_DATA_PARMS structure for all calls to the CardGetFirstTuple, CardGetNextTuple, and CardGetTupleData functions.
