csx_GetTupleData(9F) Kernel Functions for Drivers csx_GetTupleData(9F)NAMEcsx_GetTupleData - return the data portion of a tuple
SYNOPSIS
#include <sys/pccard.h>
int32_t csx_GetTupleData(client_handle_t ch, tuple_t *tu);
INTERFACE LEVEL
Solaris DDI Specific (Solaris DDI)
PARAMETERS
ch Client handle returned from csx_RegisterClient(9F).
tu Pointer to a tuple_t structure.
DESCRIPTION
This function returns the data portion of a tuple, as returned by the
csx_GetFirstTuple(9F) and csx_GetNextTuple(9F) functions.
STRUCTURE MEMBERS
The structure members of tuple_t are:
The fields are defined as follows:
uint32_t Socket; /* socket number */
uint32_t Attributes; /* tuple attributes*/
cisdata_t DesiredTuple; /* tuple to search for*/
cisdata_t TupleOffset; /* tuple data offset*/
cisdata_t TupleDataMax; /* max tuple data size*/
cisdata_t TupleDataLen; /* actual tuple data length*/
cisdata_t TupleData[CIS_MAX_TUPLE_DATA_LEN]; /* tuple body data buffer*/
cisdata_t TupleCode; /* tuple type code*/
cisdata_t TupleLink; /* tuple link */
Socket Not used in Solaris, but for portability with
other Card Services implementations, it should
be set to the logical socket number.
Attributes Initialized by csx_GetFirstTuple(9F) or
csx_GetNextTuple(9F); the client must not mod‐
ify the value in this field.
DesiredTuple Initialized by csx_GetFirstTuple(9F) or
csx_GetNextTuple(9F); the client must not mod‐
ify the value in this field.
TupleOffset This field allows partial tuple information to
be retrieved, starting anywhere within the
tuple.
TupleDataMax This field is the size of the tuple data buffer
that Card Services uses to return raw tuple
data from csx_GetTupleData(9F). It can be
larger than the number of bytes in the tuple
data body. Card Services ignores any value
placed here by the client.
TupleDataLen This field is the actual size of the tuple data
body. It represents the number of tuple data
body bytes returned.
TupleData This field is an array of bytes containing the
raw tuple data body contents.
TupleCode Initialized by csx_GetFirstTuple(9F) or
csx_GetNextTuple(9F); the client must not mod‐
ify the value in this field.
TupleLink Initialized by csx_GetFirstTuple(9F) or
csx_GetNextTuple(9F); the client must not mod‐
ify the value in this field.
RETURN VALUES
CS_SUCCESS Successful operation.
CS_BAD_HANDLE Client handle is invalid.
CS_BAD_ARGS Data from prior csx_GetFirstTuple(9F)
or csx_GetNextTuple(9F) is corrupt.
CS_NO_CARD No PC Card in socket.
CS_NO_CIS No Card Information Structure (CIS) on
PC Card.
CS_NO_MORE_ITEMS Card Services was not able to read the
tuple from the PC Card.
CS_UNSUPPORTED_FUNCTION No PCMCIA hardware installed.
CONTEXT
This function may be called from user or kernel context.
