NAME
lgrp_view - get view of lgroup hierarchy
SYNOPSIS

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

lgrp_view_t lgrp_view(lgrp_cookie_t cookie);
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 successful completion, lgrp_view() returns the view for the snapshot of the lgroup hierarchy represented by the given cookie. Otherwise, -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.
