.SH DESCRIPTION
.sp
.LP
The functions \fBcsx_GetFirstTuple()\fR and \fBcsx_GetNextTuple()\fR return the
first and next tuple, respectively, of the specified type in the Card
Information Structure (CIS) for the specified socket.
.SH STRUCTURE MEMBERS
.sp
.LP
The structure members of \fBtuple_t\fR are:
.sp
.in +2
.nf
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 */
.fi

.LP
The fields are defined as follows:
.sp
.ne 2
.na
\fB\fBSocket\fR\fR
.ad
.RS 23n
Not used in Solaris, but for portability with other Card Services
implementations, it should be set to the logical socket number.
.RE

.sp
.ne 2
.na
\fB\fBAttributes\fR\fR
.ad
.RS 23n
This field is bit-mapped. The following bits are defined:
.sp
.ne 2
.na
\fBTUPLE_RETURN_LINK\fR
.ad
.sp .6
.RS 4n
Return link tuples if set. The following are link tuples and will only be
returned by this function if the \fBTUPLE_RETURN_LINK\fR bit in the
\fBAttributes\fR field is set:
.sp
.in +2
.nf
	CISTPL_NULL	CISTPL_LONGLINK_MFC
	CISTPL_LONGLINK_A	CISTPL_LINKTARGET

.fi

.RE

.sp
.ne 2

\fBTUPLE_RETURN_IGNORED_TUPLES\fR
.ad
.sp .6
.RS 4n
Return ignored tuples if set. Ignored tuples will be returned by this function
if the \fBTUPLE_RETURN_IGNORED_TUPLES\fR bit in the \fBAttributes\fR field is
set, see \fBtuple\fR(9S) for more information. The \fBCIS \fRis parsed from the
location setup by the previous \fBcsx_GetFirstTuple()\fR or
\fBcsx_GetNextTuple()\fR request.

.sp
.ne 2
.na
\fB\fBDesiredTuple\fR\fR
.ad
.RS 23n
This field is the tuple value desired. If it is \fBRETURN_FIRST_TUPLE,\fR the
very first tuple of the \fBCIS \fRis returned (if it exists). If this field is
set to \fBRETURN_NEXT_TUPLE,\fR the very next tuple of the \fBCIS \fRis
returned (if it exists). If the \fBDesiredTuple\fR field is any other value on
entry, the \fBCIS \fRis searched in an attempt to locate a tuple which matches.
.RE

.sp
.ne 2
.na
\fB\fBTupleCode,TupleLink\fR\fR
.ad
.RS 23n
These fields are the values returned from the tuple found. If there are no
tuples on the card, \fBCS_NO_MORE_ITEMS\fR is returned.
.RE

.sp
.LP
Since the \fBcsx_GetFirstTuple()\fR, \fBcsx_GetNextTuple()\fR, and
\fBcsx_GetTupleData\fR(9F) functions all share the same \fBtuple_t\fR
structure, some fields in the \fBtuple_t\fR structure are unused or reserved
when calling this function and these fields must not be initialized by the
client.
