csx_GetFirstTuple, csx_GetNextTuple - return Card Information Structure tuple
#include <sys/pccard.h> int32_t csx_GetFirstTuple(client_handle_t ch, tuple_t *tu);
int32_t csx_GetNextTuple(client_handle_t ch, tuple_t *tu);
Solaris DDI Specific (Solaris DDI)
Client handle returned from csx_RegisterClient(9F).
Pointer to a tuple_t structure.
The functions csx_GetFirstTuple() and csx_GetNextTuple() return the first and next tuple, respectively, of the specified type in the Card Information Structure (CIS) for the specified socket.
The structure members of tuple_t are:
uint32_t Socket; /* socket number */ uint32_t Attributes; /* Attributes */ cisdata_t DesiredTuple; /* tuple to search for or flags */ cisdata_t TupleCode; /* tuple type code */ cisdata_t TupleLink; /* tuple data body size */
The fields are defined as follows:
Not used in Solaris, but for portability with other Card Services implementations, it should be set to the logical socket number.
This field is bit-mapped. The following bits are defined:
Return link tuples if set. The following are link tuples and will only be returned by this function if the TUPLE_RETURN_LINK bit in the Attributes field is set:
CISTPL_NULL CISTPL_LONGLINK_MFC CISTPL_LONGLINK_A CISTPL_LINKTARGET CISTPL_LONGLINK_C CISTPL_NO_LINK CISTPL_LONGLINK_CB CISTPL_END
Return ignored tuples if set. Ignored tuples will be returned by this function if the TUPLE_RETURN_IGNORED_TUPLES bit in the Attributes field is set, see tuple(9S) for more information. The CIS is parsed from the location setup by the previous csx_GetFirstTuple() or csx_GetNextTuple() request.
This field is the tuple value desired. If it is RETURN_FIRST_TUPLE, the very first tuple of the CIS is returned (if it exists). If this field is set to RETURN_NEXT_TUPLE, the very next tuple of the CIS is returned (if it exists). If the DesiredTuple field is any other value on entry, the CIS is searched in an attempt to locate a tuple which matches.
These fields are the values returned from the tuple found. If there are no tuples on the card, CS_NO_MORE_ITEMS is returned.
Since the csx_GetFirstTuple(), csx_GetNextTuple(), and csx_GetTupleData(9F) functions all share the same tuple_t structure, some fields in the tuple_t structure are unused or reserved when calling this function and these fields must not be initialized by the client.
Client handle is invalid.
No PC Card in socket.
No Card Information Structure (CIS) on PC card.
Desired tuple not found.
No PCMCIA hardware installed.
These functions may be called from user or kernel context.
