lgrp_parents(3LGRP)					 Locality Group Library Functions				       lgrp_parents(3LGRP)

NAME
lgrp_parents - get parents of given lgroup SYNOPSIS
cc [ flag ... ] file... -llgrp [ library ... ] #include <sys/lgrp_user.h> int lgrp_parents(lgrp_cookie_t cookie, lgrp_id_t child, lgrp_id_t *lgrp_array, uint_t lgrp_array_size); DESCRIPTION
The lgrp_parents() function takes a cookie representing a snapshot of the lgroup hierarchy obtained from lgrp_init(3LGRP) and returns the number of parent lgroups of the specified lgroup. If lgrp_array is non-null and the lgrp_array_size is non-zero, the array is filled with as many of the parent lgroup IDs as will fit given the size of the array. For the root lgroup, the number of parents returned is 0 and the lgrp_array argument is not filled in. RETURN VALUES
Upon successful completion, lgrp_parents() returns the number of parent lgroup IDs. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The lgrp_parents() function will fail if: EINVAL The specified cookie or lgroup ID is not valid. ESRCH The specified lgroup ID was not found. ATTRIBUTES

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