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

DESCRIPTION
The lgrp_view() function takes a cookie representing the snapshot of the lgroup hierarchy obtained from lgrp_init(3LGRP) and returns the
snapshot's view of the lgroup hierarchy.
If the given view is LGRP_VIEW_CALLER, the snapshot contains only the resources that are available to the caller (such as those with
respect to processor sets). When the view is LGRP_VIEW_OS, the snapshot contains what is available to the operating system.
RETURN VALUES
Upon succesful completion, lgrp_view() returns the view for the snapshot of the lgroup hierarchy represented by the given cookie. Other-
wise, -1 is returned and errno is set to indicate the error.
ERRORS
The lgrp_view() function will fail if:
EINVAL The cookie is not valid.
