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. ATTRIBUTES

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); 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. 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. 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.
