.SH DESCRIPTION
.sp
.LP
This function validates the Card Information Structure (CIS) on the \fBPC\fR
Card in the specified socket.
.SH STRUCTURE MEMBERS
.sp
.LP
The structure members of \fBcisinfo_t\fR are:
.sp
.in +2
.nf
 uint32_t     Socket;    /* socket number to validate CIS on */
  uint32_t     Chains;    /* number of tuple chains in CIS */
  uint32_t     Tuples;    /* total number of tuples in CIS */
.fi
.in -2

.sp
.LP
The fields are defined as follows:
.sp
.ne 2
.mk
.na
\fB\fBSocket\fR\fR
.ad
.RS 10n
.rt  
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
.mk
.na
\fB\fBChains\fR\fR
.ad
.RS 10n
.rt  
This field returns the number of valid tuple chains located in the \fBCIS\fR.
If \fB0\fR is returned, the \fBCIS\fR is not valid.
.RE

.sp
.ne 2
.mk
.na
\fB\fBTuples\fR\fR
.ad
.RS 10n
.rt  
This field is a Solaris-specific extension and it returns the total number of
tuples on all the chains in the \fBPC\fR Card's \fBCIS\fR.
