kstat_lookup(3KSTAT)					Kernel Statistics Library Functions				      kstat_lookup(3KSTAT)

NAME

       kstat_lookup, kstat_data_lookup - find a kstat by name

SYNOPSIS

       cc [ flag... ] file... -lkstat [ library...]
       #include <kstat.h>

       kstat_t *kstat_lookup(kstat_ctl_t *kc, char *ks_module, int ks_instance, char *ks_name);

       void *kstat_data_lookup(kstat_t *ksp, char *name);

DESCRIPTION

       The  kstat_lookup()  function  traverses  the  kstat  chain,  kc->kc_chain, searching for a kstat with the same ks_module, ks_instance, and
       ks_name fields; this triplet uniquely identifies a kstat.  If ks_module is NULL, ks_instance is	-1, or ks_name is NULL, those fields  will
       be ignored in the search.  For example, kstat_lookup(kc, NULL, -1, "foo")  will find the first kstat with name "foo".

       The kstat_data_lookup() function searches the kstat's data section for the record with the specified name. This operation is valid only for
       those kstat types that have named data records: KSTAT_TYPE_NAMED and KSTAT_TYPE_TIMER.

RETURN VALUES

       The kstat_lookup() function returns a pointer to the requested kstat if it is found. Otherwise it returns NULL and sets errno  to  indicate
       the error.

       The kstat_data_lookup() function returns a pointer to the requested data record if it is found. Otherwise it returns NULL and sets errno to
       indicate the error .

ERRORS

       The kstat_lookup() and kstat_data_lookup() functions will fail if:

       EINVAL	       An attempt was made to look up data for a kstat that was not of type KSTAT_TYPE_NAMED or KSTAT_TYPE_TIMER.

       ENOENT	       The requested kstat could not be found.
