kstat_named - structure for named kstats

Interface Level

Solaris DDI specific (Solaris 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.

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().
