.SH DESCRIPTION
.sp
.LP
\fBkstat_named_init()\fR associates a name and a type with a
\fBkstat_named\fR(9S) structure.
.sp
.LP
\fBkstat_named_setstr()\fR associates \fIstr\fR with the named kstat \fBknp\fR.
It is an error for \fBknp\fR to be of type other than \fBKSTAT_DATA_STRING\fR.
The string argument must remain valid even after the function that is calling
\fBkstat_named_setstr()\fR is returned. This is the only supported method of
changing the value of long strings.
.SH RETURN VALUES
.sp
.LP
None.
.SH CONTEXT
.sp
.LP
\fBkstat_named_init()\fR and \fBkstat_named_setstr()\fR can be called from user
or kernel context.
