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 num-
       ber 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, lgroup ID, or one of the flags is not valid.

       ESRCH	 The specified lgroup ID was not found.
