NAME

lgrp_resources - get lgroup resources of given lgroup

SYNOPSIS

cc [ flag ... ] file... -llgrp [ library ... ]
#include <sys/lgrp_user.h>
int lgrp_resources(lgrp_cookie_t cookie, lgrp_id_t lgrp,


     lgrp_id_t *lgrpids, uint_t count, lgrp_rsrc_t type);

DESCRIPTION

The lgrp_resources() function takes a cookie representing a snapshot of the lgroup hierarchy obtained from lgrp_init(3LGRP) and returns the number of resources in the lgroup specified by lgrp. The resources are represented by a set of lgroups in which each lgroup directly contains CPU and/or memory resources.

The type argument should be set to one of the following values to specify whether the CPU or memory resources should be returned:

LGRP_RSRC_CPU      /* CPU resources */
LGRP_RSRC_MEM      /* Memory resources */

If the lgrpids[] argument is non-null and the count argument is non-zero, lgrp_resources() stores up to the specified count of lgroup IDs into the lgrpids[] array.

RETURN VALUES

Upon successful completion, lgrp_resources() returns the number of lgroup resources. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

The lgrp_resources() function will fail if:

EINVAL

The specified cookie, lgroup ID, or type is not valid.

ESRCH

The specified lgroup ID was not found.
