.SH DESCRIPTION
.sp
.LP
This function parses the Link Target tuple, \fBCISTPL_LINKTARGET,\fR into a form usable by \fBPC\fRCard drivers.
.sp
.LP
The \fBCISTPL_LINKTARGET\fR tuple is used to verify that tuple chains other than the primary chain are valid. All secondary tuple chains are required to contain this tuple as the first tuple of the chain.
.SH STRUCTURE MEMBERS
.sp
.LP
The structure members of \fBcistpl_linktarget_t\fR are:
.sp
.in +2
.nf
uint32_t   length;
