NAME

kstat_named - structure for named kstats

SYNOPSIS

#include <sys/types.h>
#include <sys/kstat.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>

INTERFACE LEVEL

illumos DDI specific (illumos DDI)

DESCRIPTION

Named kstats are an array of name-value pairs. These pairs are kept in the kstat_named structure. When a kstat is created by kstat_create(9F), the driver specifies how many of these structures will be allocated. The structures are returned as an array pointed to by the ks_data field.

STRUCTURE MEMBERS

union {


          char                   c[16];


          long                   l;


          ulong_t                ul;


          longlong_t             ll;


          u_longlong_t           ull;
} value;  /* value of counter */

The only member exposed to drivers is the value member. This field is a union of several data types. The driver must specify which type it will use in the call to kstat_named_init().
