kstat_open(3kstat)

Kernel Statistics Library Functions                         kstat_open(3KSTAT)



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


       The kstat_close() function frees all  resources  that  were  associated
       with  kc.  This  is  performed automatically on the exit() and execve()
       functions. For more information, see  the  exit(2)  and  execve(2)  man
       pages.

RETURN VALUES
       Upon  successful  completion, kstat_open() returns a pointer to a kstat
       control structure. Otherwise, it returns NULL, no resources  are  allo‐
       cated, and errno is set to indicate the error.


       Upon  successful  completion, kstat_close() returns 0. Otherwise, −1 is
       returned and errno is set to indicate the error.

ERRORS
       The kstat_open() function will fail if:

       ENOMEM       Insufficient storage space is available.


       EAGAIN       The kstat was temporarily unavailable for reading or writ‐
                    ing.


       ENXIO        The given kstat could not be located for reading.


       EOVERFLOW    The data for the given kstat was too large to be stored in
                    the structure.



       The kstat_open() function can also return  the  error  values  for  the
       open() function. For more information, see the open(2) man page.


       The  kstat_close()  function  can  also return the error values for the
       close() function. For more information, see the close(2) man page.

       The  kstat_open()  function  is Safe. The kstat_close() function is MT-
       Safe with the exception  that  only  one  thread  may  actively  use  a
       kstat_ctl_t  * value at any time. Synchronization is left to the appli‐
       cation.

NOTES
       The  kstat_open()  and kstat_close() functions are deprecated. They may
       be removed in a future release of Oracle Solaris. Use the kstat2_open()
       and  kstat2_close()  functions  instead.  For more information, see the
       kstat2_open(3KSTAT2) and kstat2_close(3KSTAT2) man pages.
