 120 .SH DESCRIPTION
 121 .LP
 122 \fBkstat_named_init()\fR associates a name and a type with a
 123 \fBkstat_named\fR(9S) structure.
 124 .sp
 125 .LP
 126 \fBkstat_named_setstr()\fR associates \fIstr\fR with the named kstat \fBknp\fR.
 127 It is an error for \fBknp\fR to be of type other than \fBKSTAT_DATA_STRING\fR.
 128 The string argument must remain valid even after the function that is calling
 129 \fBkstat_named_setstr()\fR is returned. If \fBKSTAT_DATA_STRING\fR is used in a
 130 persistent kstat the string argument must remain valid even after the module
 131 that created the kstat is unloaded. This is the only supported method of changing
 132 the value of long strings.
 133 .SH RETURN VALUES
 134 .LP
 135 None.
 136 .SH CONTEXT
 137 .LP
 138 \fBkstat_named_init()\fR and \fBkstat_named_setstr()\fR can be called from user
 139 or kernel context.
