lgrp_cookie_stale(3lgrp)

Locality Group Library Functions                      lgrp_cookie_stale(3LGRP)



NAME
       lgrp_cookie_stale  -  determine whether snapshot of lgroup hierarchy is
       stale

SYNOPSIS
       cc [ flag ... ] file... -llgrp [ library ... ]
       #include <sys/lgrp_user.h>

       int lgrp_cookie_stale(lgrp_cookie_t cookie);

DESCRIPTION
       The lgrp_cookie_stale() function takes a cookie representing the  snap‐
       shot of the lgroup hierarchy obtained from lgrp_init(3LGRP) and returns
       whether it is stale. The snapshot can become out-of-date for  a  number
       of  reasons  depending  on  its  view.  If  the snapshot was taken with
       LGRP_VIEW_OS, changes in the lgroup hierarchy from dynamic reconfigura‐
       tion,  CPU  on/offline,  or  other conditions can cause the snapshot to
       become out-of-date. A  snapshot  taken  with  LGRP_VIEW_CALLER  can  be
       affected  by the caller's processor set binding and changes in its pro‐
       cessor set itself, as well as changes in the lgroup hierarchy.


       If the snapshot needs to be updated, lgrp_fini(3LGRP) should be  called
       with  the  old  cookie and lgrp_init() should be called to obtain a new
       snapshot.

RETURN VALUES
       Upon successful completion,  lgrp_cookie_stale()  returns  whether  the
       cookie  is  stale.  Otherwise, it returns −1 and sets errno to indicate
       the error.

ERRORS
       The lgrp_cookie_stale() function will fail if:

       EINVAL    The cookie is NULL.
