KSTAT_NAMED(9S) Data Structures for Drivers KSTAT_NAMED(9S)

NAME

kstat_named - structure for named kstats

SYNOPSIS

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().
