kstat_open(3K)

NAME

kstat_open, kstat_close − initialize kernel statistics facility

SYNOPSIS

cc [ flag... ] file... -lkstat [ library... ]

#include <kstat.h>

kstat_ctl_t ∗kstat_open(void);

int kstat_close(kstat_ctl_t ∗kc);

DESCRIPTION

kstat_open() initializes a kstat control structure, which provides access to the kernel statistics library. It returns a pointer to this structure, which must be supplied as the kc argument in subsequent libkstat function calls.

kstat_close() frees all resources that were associated with kc. This is done automatically on exit(2) and execve() (see exec(2)).

RETURN VALUES

kstat_open() returns a pointer to a kstat control structure. On failure, it returns NULL and no resources are allocated.

kstat_close() returns 0 on success, −1 on failure.
