NAME
lgrp_fini - finished using lgroup interface SYNOPSIS
cc [ flag... ] file... -llgrp [ library... ] #include <sys/lgrp_user.h> int lgrp_fini(lgrp_cookie_t cookie); DESCRIPTION
The lgrp_fini() function takes a cookie, frees the snapshot of the lgroup hierarchy created by lgrp_init(3LGRP), and cleans up anything else set up by lgrp_init(). After this function is called, any memory allocated and returned by the lgroup interface might no longer be valid and should not be used. RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The lgrp_fini() function will fail if: EINVAL The cookie is not valid. ATTRIBUTES

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 snapshot 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 The snapshot can become out-of-date for a number of reasons depending on its view.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the lgroup hierarchy from dynamic reconfiguration, CPU on/offline, or other conditions can cause the snapshot to become out-of-date.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 processor 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 not valid. ATTRIBUTES
