 kstat_named_init 9F "29 Feb 2008" "SunOS 5.11" "Kernel Functions for Drivers"
 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, const char *name,
 uchar_t data_type);


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


 INTERFACE LEVEL

Solaris DDI specific (Solaris DDI)
 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

Obsolete. Use KSTAT_DATA_INT64.


KSTAT_DATA_ULONGLONG

Obsolete. Use KSTAT_DATA_UINT64.


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.
The string argument must remain valid even after the function that is calling
kstat_named_setstr() is returned. 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.
