.SH NAME
kstat_named \- structure for named kstats
.SH SYNOPSIS

.SH DESCRIPTION
Named \fBkstats\fR are an array of name-value pairs. These pairs are kept in
the \fBkstat_named\fR structure. When a \fBkstat\fR is created by
\fBkstat_create\fR(9F), the driver specifies how many of these structures will
be allocated. The structures are returned as an array pointed to by the
\fBks_data\fR field.

The only member exposed to drivers is the \fBvalue\fR member. This field is a
union of several data types. The driver must specify which type it will use in
the call to \fBkstat_named_init()\fR.
