NAME

kstat_named_init, kstat_named_setstr - initialize a named kstat

SYNOPSIS

#include <sys/types.h> #include <sys/kstat.h> void kstat_named_init(kstat_named_t *knp, char *name, uchar_t data_type);

void kstat_named_setstr(kstat_named_t *knp, const char *str);

PARAMETERS

knp

Pointer to a kstat_named(9S) structure.

name

The name of the statistic.

data_type

The type of value. This indicates which field of the kstat_named(9S) structure should be used. Valid values are:

KSTAT_DATA_CHAR: The "char" field.
KSTAT_DATA_LONG: The "long" field.
KSTAT_DATA_ULONG: The "unsigned long" field.
KSTAT_DATA_LONGLONG: The "long long" field.
KSTAT_DATA_ULONGLONG: The "unsigned long long" field.
KSTAT_DATA_STRING: Arbitrary length "long string" field.

str

Pointer to a NULL-terminated string.

DESCRIPTION

kstat_named_init() associates a name and a type with a kstat_named(9S) structure.

kstat_named_setstr() associates str with the named kstat knp. It is an error for knp to be of type other than KSTAT_DATA_STRING. This is the only supported method of changing the value of long strings.

RETURN VALUES

None.

CONTEXT

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