kstat_data_lookup
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.
