PARAMETERS

25       knp          Pointer to a kstat_named(9S) structure.
26
27
28       name         The name of the statistic.
29
30
31       data_type    The  type  of  value.  This  indicates  which field of the
32                    kstat_named(9S) structure should  be  used.  Valid  values
33                    are:
34
35                    KSTAT_DATA_CHAR         The "char" field.
36
37
38                    KSTAT_DATA_LONG         The "long" field.
39
40
41                    KSTAT_DATA_ULONG        The "unsigned long" field.
42
43
44                    KSTAT_DATA_LONGLONG     Obsolete. Use KSTAT_DATA_INT64.
45
46
47                    KSTAT_DATA_ULONGLONG    Obsolete. Use KSTAT_DATA_UINT64.
48
49
50                    KSTAT_DATA_STRING       Arbitrary   length  "long  string"
51                                            field.

DESCRIPTION

59       kstat_named_init() associates a name and a type with a  kstat_named(9S)
60       structure.
61
62
63       kstat_named_setstr()  associates str with the named kstat knp. It is an
64       error for knp to be of type other than  KSTAT_DATA_STRING.  The  string
65       argument  must  remain  valid  even  after the function that is calling
66       kstat_named_setstr() is returned. This is the only supported method  of
67       changing the value of long strings.
68

RETURN VALUES

70       None.
71

CONTEXT

73       kstat_named_init()  and kstat_named_setstr() can be called from user or
74       kernel context.
