kstat_named - structure for named kstats

illumos DDI specific (illumos DDI) 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.

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().

kstat_create (9F), kstat_named_init (9F)
