CARD_DATA_PARMS

The CARD_DATA_PARMS structure contains tuple information passed to CardGetTupleData.

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

Specifies a handle to a socket and function pair.

fAttributes

Specify TUPLE_RETURN_LINKS (first bit is one) to return link tuples. (Input)

uDesiredTuple

Specifies the desired tuple code. If 0xFF, then the first tuple encountered is returned. See PC Card Tuple Codes (Input)

uTupleOffset

Specifies an offset into tuple data. (Input)

fFlags

Specifies flags used internally by Card Services. A driver must maintain this value between calls to tuple functions. (Input/Output)

uLinkOffset

Specifies a Tuple link offset used internally by Card Services. A driver must maintain this value between calls to tuple functions. (Input/Output)

uCISOffset

Specifies CIS state information used internally by Card Services. A driver must maintain this value between calls to tuple functions. (Input/Output)

uBufLen

Specifies the length (maximum number of bytes) of tuple data. (Input)

uDataLen

Specifies the length (actual number of bytes) of tuple data. (Output)

Remarks

Because this structure is similar to the CARD_TUPLE_PARMS structure, a driver could potentially use a single CARD_DATA_PARMS structure for all calls to CardGetFirstTuple, CardGetNextTuple and CardGetTupleData.
