lgrp_cpus(3lgrp)
Locality Group Library Functions lgrp_cpus(3LGRP)
NAME
lgrp_cpus - get CPU IDs contained in specified lgroup
SYNOPSIS
cc [ flag... ] file... -llgrp [ library... ]
#include <sys/lgrp_user.h>
int lgrp_cpus(lgrp_cookie_t cookie, lgrp_id_t lgrp,
processorid_t *cpuids, uint_t count, int content);
DESCRIPTION
The lgrp_cpus() function takes a cookie representing a snapshot of the
lgroup hierarchy obtained from lgrp_init(3LGRP) and returns the number
of CPUs in the lgroup specified by lgrp. If both the cpuids[] argument
is non-null and the count is non-zero, lgrp_cpus() stores up to the
specified count of CPU IDs into the cpuids[] array.
The content argument should be set to one of the following values to
specify whether the direct contents or everything in this lgroup should
be returned:
LGRP_CONTENT_ALL /* everything in this lgroup */
LGRP_CONTENT_DIRECT /* directly contained in lgroup */
LGRP_CONTENT_HIERARCHY /* everything within this hierarchy (for
compatibility only, use LGRP_CONTENT_ALL) */
The LGRP_CONTENT_HIERARCHY value can still be used, but is being
replaced by LGRP_CONTENT_ALL.
RETURN VALUES
Upon successful completion, the number of CPUs in the given lgroup is
returned. Otherwise, −1 is returned and errno is set to indicate the
error.
ERRORS
The lgrp_cpus() function will fail if:
EINVAL The specified cookie is NULL, or the lgroup ID or one of the
flags is not valid.
ESRCH The specified lgroup ID was not found.
